RTX 4080 & 7900 XTX/XT benchmarks DCS

Sorry to disappoint, but from initial testing and troubleshooting for the past two days with a friend of mine with a 5800X3D, 64 GB of RAM, a Reverb G2, and his new ASRock 7900 XTX Phantom Gaming, VR fps in both OpenXR AND SteamVR is utterly garbage. Running the G2 @ 90hz at around native resolution, on F/A-18C Free Flight Caucasus on medium-high settings (we tried low settings, not much difference), he's only managing 30-45 FPS, SOMETIMES 50-60 but doesn't even matter because Motion Reprojection (MR) is broken on both. MR simply doesn't work on either Mixed Reality + OXR, or Mixed Reality for SteamVR. It doesn't matter if it's forced on or automatic. It simply doesn't work. We have tried both the old 23.2.1 and new 23.2.2 drivers using both the AMD cleaner utility or DDU to remove the drivers before installing the other.

For reference, I have a 12600k, 3080, and Reverb G2 @ 90hz and I am getting SIGNIFICANTLY better performance than him on the same exact medium-high settings and near native resolution, sometimes even maxing out at 90 FPS on in F-18 Caucasus free flight when uncapped, and basically not budging at the MR 45 FPS target. We were wracking our heads trying to figure out if his GPU was somehow defective or if we had messed up the driver installation somehow. We uninstalled and reinstalled nearly every VR related program short of reinstalling DCS and Windows. Same performance stated initially or worse depending on what we did. SVR saw the worst performance which wasn't surprising but I still recommended trying SVR over OXR because the motion reprojection implementation is still leagues better.

My guess, is that AMD's support for VR at the driver level for the 7900 XTX is simply not there right now, and there's no telling when there will be.

 

Unfortunately I second this. I am running a AMD 7900XTX + 5800X3D + 32GB +NVME +Samsung Odyssey + headset and the FPS is between 30-45 most of the time. Sometimes I get 50-60 but that is rare. I saw that the MSAA impact the performance a bit but it is pretty same with a different combination of settings. My headset is an old one, so the resolution is even lower than G2. 

On flatscreen, the performance is great though. Everything full on a 34 inch 21:9 display I get 80-100 FPS easily. 

The VR is clearly broken on the 7900XTX at the moment. I think it is a driver issue because changing the settings even does not have a huge impact. And you can see that high resolution headsets like G2 and lower resolution headsets like Odyssey+ have the same performance with different combination of settings.

I would not recommend 7900XTX for VR at the moment.  I don't know about the streaming headsets like Q2 or Pico 4 and the performance on those may be different.

I've also read a lot in the AMD forum over the past few days and in my opinion the latest state was that there is a bug with all directly connected headsets with AMD cards of the RX7000 series.

That includes the reverb.

It would be interesting if you have a Quest 2 or Pico 4, or if you can find one to test it against.

Because with these headsets there shouldn't be this one bug.

There was talk, with reverb performance well below the RX6900 and with a Quest 2 significantly faster than the 6900XT.

As a Pico 4 user, there have been much more damage done for VR by the DCS update than AMD drivers.

Those drivers are holding the performance of the GPU by about 9.3% at 4K MSAA in 3DMark test, but this issue appeared after the DCS update and the image quality + FPS I obtained when I tested my GPU before the update were really good, I managed 4 test videos before the DCS update destroyed my VR performance.

It is possible that people with slower AMD GPUs can experience issues in VR because of drivers that I don't see, from my PoV, on top of the loss of performances, we have some mesh-maps distortion in Elite Dangerous, making the moons where the engineers are based look cracked like nuts, making it impossible to access them and engineer our ships/systems.

Now my visuals are of much lower quality, better than a month ago but I can't see the electric lines as I did when I flew this test on the same map (Nellis AFB) with the same A-C, and much lower settings, the side image is jerky, I pay particular attention to this and it is the reason why I fly at three top then look on the side.

So both RX7000 are suffering from AMD drivers but in DCS also from the update, particularly those using the Pico4.

Not only, I had issues in VR shortly after I uploaded this video, before I updated my drivers.

That's got nothing to do with the 7900XTX itself, but in the case of Picoi 4 users, the DCS update first and foremost, AMD released 3 drivers in  2 month, proof that they know there is a problem and it didn't make things any better, by your reasoning I wouldn't recommend Pico 4 either but both are great.

Since I was lucky enough to start testing my GPU before both the DCS and AMD updates I know exactly what it is capable of and it's a great card let down by terrible drivers, as for the DCS update, well we all expect a good, solid update bringing a significant boost in performance, even if it's late, it will do.

There are some solutions for AMD users, and also those with lower specs PCs HERE I now have a much improved cockpit view with readable, sharps instruments, but no real improvement in environment, for example I can't see the electric lines before I got my nose on them, now good for three top flight and side image is jerky.

Just in passing, in any serious (and not drivers biased) tests, the RX 7900 XTX is faster than the 4080 at 4K, that's enough to justify my choice for this card since my requirements were VR at 4K 2 X MSAA.

I forgot: At the time of the last video, my GPU bandwidth was reduced by 50%, because I couldn't use the PCI_E1 slot, issue resolved now but it says a lot about the capability of the card.

Good morning,

Maybe you can really screenshot your settings and measure your fps, maybe with FpsVR.

That would give people here a clear picture of how the 7900XTX is performing.

And I also think it's important now, with update problems, and wouldn't just wait for things to get better again.

Well, actually I did when I started my first tests, for the story, I used (or tried to) afterburner and the FPS you see in one or two of those videos is not that of the actual game but screen recording of the replay... I didn't know about FpsVR despite the fact that it is already in my Steam library, thanks for the tip.

The goal was to push the card to its maximum and see how to improve the visual, to achieve this, I flew very low level where the terrain details redraw is more demanding than mid or high altitude, I came close to something very smooth with high level of details in the last video before I was able to find Afterburner settings so I don't know the FPS but it was smooth.

With the Pico4, the clarity of the visual obtained was indiscernible to that of my screen, the difference is just that you can see the grid, like playing with your nose on the screen, resolution was at its maximum, Display set to Ultra, Bitrate 150Mbps, Codec HEVC and Refresh Rate 90Hz, I was able to see the electric line from much further away than today.

Sapphire Radeon RX 7900 XTX Nitro+ Vapor-X 24GB GDDR6 first run.

I was also setting my BIOS, made back-to-back performance comparative between my PC configurations (upgrades) and the PCI_E1 slot was causing trouble, setting itself back to default causing the card not to output any signal.

With the help of MSI support, I was able to solve the problem by using PCI_E2 and setting the BIOS back to PCI_E1 Gen 1 but it happened after I made the last videos, so all I can say right now is that with the right driver, the card seems to be very strong at 4K.

We all hope for AMD to pull their finger out and provide with a proper driver (unless they are committing commercial suicide)...

From my 3DMark Pro tests, I lost minimum 9.3% in Combine Score  at 4K 2 X MSAA Firestrike Ultra, and when I say minimum it is because I lost the previous tests results but I'm sure it was gone well above 20 000.

The best result I obtained after driver update is with manually under-volt with 19 040, in default settings, it's more like 18 495, then again, the last two drivers causes the card to crash when under-volt is selected, manual of automatic. there is absolutely no improvement with the last driver release, some people are sending their GPU back which is perhaps a bit overdone but I understand why.

This card has a huge potential but is hold back by bad drivers, especially with 10% loss plus <> 3% you can expect from under-volting it, the RX 7900 XTX Nitro+ Vapor-X  runs cool under load and never did throttle back due to thermal limits, if it haven't been for those issues, I would have enjoyed my VR experience a lot more and be able to provide with proper tests including FPS.

So I'm not blaming the GPU but the bozos who released 3 drivers in two month, made the one that worked unavailable to players, all of which with no positive results to show for their (and our) troubles...

Setting " Pixel Density" as 1.6  is very interesting,  I guess theoretically it should increase the clarity if it is shifted from 1.0.   However, what I understand is that change can affect many "add-on" programs and we have been always reminded to leave the number as 1.0.

I flew 3 different aircraft, the Mirage F1 and 2000C and the F-15, what this first Pixel Density setting did was to give me a good clarity at the cost of more jerky play, in fact it was the first setting I started to lower to get a smoother game, then everything not affecting the clarity and cockpit instruments readability too much.

From 16 to 13/14 there is little difference visible with the Pico4, there could more noticeable differences with a high end headset, I can't tell.

Setting the screen resolution using: / Saved Games / DCS / Config/ Options.lua ["graphics"] 800 to 100 and 10280 to 320 leaves me with a very small repeater in the middle of the screen, it did reduce the load on the card enough for me to notice an improvement in the readability of the instruments after all the losses with Driver and VR update, not so much with environment...

It's OK as long as you start the game with your mouse cursor inside the screen and disable the option "cursor confined to game windows", or the cursor can go AWOL.

It takes some time until the HD version is up, it was mentioned 45 min.

I just tested everything again, everything identical except a new driver version and the new Multi Threading. See by yourself:

Where it went down below 60 FPS before, it now is in the 70s for a very short period of time, mostly higher. Overall the FPS are higher or at least more consistent.

I'm wondering if anyone has run into this issue with a 7900XTX.

 

Mid-flight the game hard locks to 65 FPS which is 60% gpu utilization (1440UW mostly high settings.) If I pause the game, GPU util goes to 100% with 175 FPS. CPU seems to be running the exact same either way. Any ideas?

 

Edit: Did a little more googling, either iUFC or DCSDTC make an export.lua modification that limits FPS. Commenting out those lines fixed the issue. See this thread for more details:

Microsoft Automatic Updates have a lot to do with the XTX loss of performances, AMD also messaged me regarding Microsoft replacing their native drivers with their own.

After an update, I lost <> 10% score in 3DMark Pro scores; Firestrike 4K 2 X MSAA, the date corresponded with the DCS "VR" update so I thought all the troubles I had running my gear in VR after the first tests came from it, but it was only partly true, same for AMD drivers, I tested 4 of them including the last one (Release Date 4/27/2023), they are not the source of the  problem.

My system runs DCS MT in VR perfectly today but not before I bumped into some article explaining how Intel CPU users were falling victim of settings embedded in one of Microsoft Updates, the culprit is MPO, ansd there is a fix. mpo_disable.reg

After updating to NVIDIA Game Ready Driver 461.09 or newer, some desktop apps may flicker or stutter when resizing the window on some PC configurations

Updated 09/29/2021 01:16 PM

When I tried to OC my GPU it crashed with mention "Driver Time Out", so I investigated and find this solution used by an AMD user, it seems to work at many levels but I am sure it is not the only thing in Windows 11 holding GPU performances.

Here are my actual settings:

The card runs smooth, no crashes, no flickering, image quality and clarity are good, performance is <> a few % of what I had before losing to whatever it was, but this app seems to be working, note that I have a very good case cooling (5 case fans + 1 CPU fan) and the temperature of the GPU stays within reasonable limits (max 81°C Junction under heavy load).

I didn't conduct further testings after taking those screenshots, with high settings in DCS MT, it managed to run smoothly and cool: 99% GPU usage at 2823MHz vs "Up to 2450 MHz" stock, so definitively, there is a lot more potential in this GPU that what one can get with those hurdles still holding it, as I figured during my first tests.

[Thinder]

Just a remark in passing.

Unless you fly at tree top level, you are not pushing your system, the best test in my case is flying the Mirage 2000 in the Caucasus map in the valley surrounded by trees, that's when your system has to pull the gloves off to get you the performances at 4K, not above the sea or at 500Ft, it doesn't have to redraw all the environment details the same way.

This GPU has a huge potential but many things holding it down, I'm still trying to figure a few things to improve performances further, but it is as I thought it was when I first tested it, a strong GPU.

That has been the hope for years. The closest thing that came to it in recent history was the 6800/6900/6950. People thought the 7900XTX was going to be a killer product up until the day testing went live, and even when that balloon was popped, people still thought it was going to get better with drivers (it had slightly, yes). 

I really hope AMD gets back to the days of 290X and 5870s, I loved those cards and they were fantastic performers. But my last two purchases were Nvidia (1080ti and now 4090) just because they provide a superior, no-compromise solution that will tick away for at least two generations.

That ‘s true. I bought their 280X, 290 and Vega64. Sucks Vega64 especially. Now 3090… and failed to get one 4090 in a few months of its launch date then decided to skip it. Hate to buy anything inflated from its already-extremely-high price tag.

And that was caused exactly by lack of effective competition which I was referring to. Make a wish that red team could make some major overhaul on their roadmap and next gen structure in 2024. Just a wish.

[Thinder]

I think thee is a misconception about what the RX 7900 XT/RX 7900 XTX are really, it first started with all the AMD bashing we've seen in Youtube done by guys who make their money with selling bad news to get moneytized, as it turned out, it was all mishandled GPU which were the subject of this topic.

Then we had people complaining about AMD drivers, including myself when I didn't know better, I was provided with a link to a pool of 4 different AMD drivers for those GPUs and tested them, there were absolutely no difference between them, but once I figured the MPO issue then I realized that there were more than Drivers involved in this.

If you look at my signature you'll see than I inform players of a message I received from AMD through their Adrenalin interface, they were warning us that Microsoft were replacing their native drivers with their own, instead of ignoring it, I decided to investigate and figured it out thanks to some NVIDIA users, because the fix was not designed for AMD GPU first, nobody in the AMD forum actually paid attention to it.

Now it seems that Microsoft have stepped up their little war with AMD and PC users, because their triggers are embedded all over Windows 11 (in my case) and no matter what, if you have Windows Automatic Update and Automatic Update Medical Service disabled, after a given number of cycles (booting I guess), one of them is going to open the door for some data you don't want in your system.

This is mainly why the RX 7900 XT/RX 7900 XTX have been under-performing just like the NVIDIA cards which suffered the effects of MPO setting did before them.

So if you're still sceptical, here is the latest: Despite Update supposedly disabled, if I boot with the internet connection ON my PC will still collect tons of cr@p from Microsift and it does affect the AMD driver, only this time, Microsoft overdone it, their replacement driver doesn't work (it did previously and you'd not notice apart for a loss of performances) and I end up with a black screen (a reboot with internet connection off solve the issue).

AMD Software Failed to Launch Because Windows Update Has Replaced the AMD Graphics Driver

>>>

Now if we look at the actual performance of my GPU after this little glitch was sorted, I compare to my 3DMark scores to that of 4080 users, I realize that those above me in ranking are ALL Watercooled with a huge level of O.C, other than that I walk all over them, especially at 4K.

Just a reminder, my RX 7900 XTX is air-cooled and can run at 2823MHz cool-no-problem, since there are still more than a few little issues to sort out, I guess this GPU can only get better, but here is your reality strike, the. RX 7900 XT/RX 7900 XTX are not the slouch we read about all the time...

And oh, I nearly forgot, until I figure where those retards at Microsoft hid their triggers, I'll use an internet cable kill switch, boot with the connection off until the AMD driver kicks-in and clean the directory. STUFF Bill Gates.

@Thinder thanks for all of your very informative posts regarding the 7900xtx. I've beennreading and following closely as I'm on the fence at the moment about upgrading my 6900xt. 

I went through a lot of the same processes as u when I got the 6900xt and found it to be a really excellent card once I understood it. I actually had both a 3080 and 6900 at the time and tested both side by side for several weeks using a reverb g2. In the end I sold the 3080 as I found the 6900 to be just better. As my g2 is getting tired it will soon also face retirement and the pico 4 has been in the shortlist but I'm doubtful i will get a decent enough performance on the 6900 to warrant that yet. The plan now will be to get a 7900xtx at a decent price and wait till the autumn and see what new headsets are available, possibly a q3. 

In the meantime i will apply much of the same tuning and tweaking to the 7900xtx as I did with the 6900. As you rightly point out, much is also to do with windows settings and updates. I also got the little windows update (sabotage) surprise but managed to fix it for now. My PC is already fairly well tuned to amd so I would like to think there is not a huge amount more. I will oc the card and add a small undervolt as well as a bit more cooling in the case. 

Keep up the testing and good posts. I do actually have quite a bit of faith in amd from my own actual experience and quite sure this card can and will deliver what I require.

I tried the recent preview driver and the VR performance gains are significant. I was getting 45-50 fps in the F14/Syria/Turkey quick action and now get around 70fps. This is a preview driver, so not even a beta but it looks promising.

This sounds very promising indeed. Let us know how u get on and if and when it releases.

I run a 5900X with a 6900XT, 1440p.

I can get quite low frame rates, now with the new F-15E, not even maxed out everything and using MT...

To start with the useful info bit; add your complete system stats to your signature, because there are some important aspects of it missing, like which O.S, what RAM are you running etc.

Then we are talking about the most demanding game I've played so far when it comes to system performances, especially in VR, so OK, you don't do VR but you still live under the same limitations as everyone else.

1) O.S. Windows will take a fair chunk of your memory if you don't optimize your system for gaming:

2) Disable/uninstall every single app you don't need, or else they keep running in the background and that's as much your game can't use.

3) Disable Automatic Update.

4) Disable MPO

If you don't trust the app here is the regedit address. Setting goes from 0 to 5, if the key doesn't exist create one.

All I know about the 5900X is that it can be O.Ced, the best you can do to improve performances for this CPU  is to bound a DDR4 BDie Cl14 kit to it is make sure it comes in one 4 X sticks kit, the 3200MHz can easily be O.Ced top 3600MHz, just make sure your CPU and case cooling are TOP.

My recommendation for AMD DDR4 CPU is this kit: G.SKILL TridentZ RGB Series 32GB (4 x 8GB) 288-Pin PC RAM DDR4 3200 (PC4 25600) Desktop Memory Model F4-3200C14Q-32GTZR, it comes on 3200 or 3600MHz. Anything equivalent from Corsair will do as well just don't mix two 2 X 1 sticks together, this can cause incompatibility issues even from the same batch, they need to be factory-tested and approved.

The way your GPU and CPUs are mounted on your motherboard can result in a cumulation of calories, a hotspot at the back of the CPU if the airflow is not exhausted fast enough, I strongly recommend mounting a high airflow fan at the back of the case.

I personally use the Noctua NF-A12x25 PWM, you got 102,1 m³/h from it, I have two, one blowing IN, the other OUT, the CPU is cooled by an Artic 7X, I have a total of 6 case fans + CPU fan.

About your 6900XT, see 3) and 4), then you can start thinking about OCing it, I can't tell you much about gains in frequencies and VRAM frequencies for this GPU but I know that it will O.C properly IF you cool it properly and of course, depending on model and maker, some are better cooled than other and it all depends on your thermal limits...

Don't panic if your O.C settings crashes after a driver update, I experienced that as well, You got to do it all over again, progressively until you reach the acceptable limits of your card, mine have reached 3000MHz running DCS in VR/MT but I'm pleased with a little less than that for as long as it is stable with the latest driver.

In short, increased Maximum Power Limit, RAM and GPU frequencies, lower Voltage, my settings are now different from thew previous one, values are only the maximum given to the card, not what it will reach under load.

Jigfio makes very good tutorials but unfortunately they are in French, what you can do is watch it and emulate what he is doing with his max figures as goal.
