AMD 7900xtx and Reverb G2

[Falken06]

Hi everyone,

Hope you all doing great. I need some help for my new config. I recently got into VR and bought my first headset (reverb g2). 

Didn't test it yet, i'm actually far from home due to work but i want to fully enjoy vr and want to upgrade my config. For the moment I have a 2070 8gb, amd ryzen 5 3600x, 32gb ram. 

The idea is to upgrade gpu and cpu and i was thinking of buying a full amd setup, with a 7900xtx gpu. 

But i read couple months ago, there was issues with Vr and 7900xtx. 

Just wanna know if the issues still there ? 

 

Is this worth it to buy a 7900xtx for vr or stay on Nvidia extravagant prices ?

 

Thanks in advance for the help. 

 

Have a nice day

I have a G2 and an AMD 6900XT and it works fine. However, the overriding consensus seems to be that NVIDIA is the way to go when it comes to VR. I haven't tried an NVIDIA card with VR yet myself but that's what I'll be switching to when I next upgrade, to see what the difference is.

Thanks for the reply, seems that the issues occurs with 7xxx series. Wanted to know if that still the case. 

 

I'm still hesitating between Nvidia and AMD.

Your two [realistic] choices are either 6950XT or pay the Nvidia tax

If reprojection is not something that you value and you are not looking to spend three thousand kangaroos then AMD is the clear choice. If your butthole is not something that you value then Nvidea is the way to go. Both ways will leave you wanting sadly*

7000 series is a huge disappointment and runs VR worse than 6000 series does. There is a frame issue with the multi-dye that was reported by Broken Silicon a while back, I have lost hope that it will be fixed. Which is a shame

Good Luck

*Unless you're rich in which case just buy the 4090 and be done with it. It's the only good card this generation for VR so far

Thanks for all the informations, you makes my choice easier. 

I'm gonna apologize to my butthole and make the Nvidia choice. 

Can already see the face of my banker

Are you using the Pico? Because if so ironicly the pico is one of the only VR headsets which preforms quite well with the 7900XTX. This is due to it not interfacing directly with the DisplayPort connector. Any VR headset which connects via USB or wireless will work great with the 7000 series

I am.

It sill demands a lot of firepower, my GPU is O.Ced and I play in MT/VR, the GPU is running at 100% nearly all the time while the 8 Cores are more often in idle waiting for it to process the frames, especially because I use quite high DCS settings and test low/fast in rich environment (between hills in a forest)...

This is where I really can see what my system can cope with, and lately I have been tweaking both the CPU with PBO2 Tuner, lowering the Voltage by -30, and the GPU with an increase in both VRAM frequency and GPU frequency + Under Voltage.

The system runs smooth and cool, I reduced the Pixel density from 1.6 to 1.2 and changed a few things, it looks as if Steam VR is having somewhat unwanted effects on the image quality too, so I'm still experimenting with setting so as to find the best compromises between FPS and image quality.

Power limit setting that you cannot see bottom right is at 15.

Mirage 2000C Map Caucasus Free Flight Test starts. I break right and dive at tree top from there, following the valley curves.

In the valley where the system have to work the hardest.

I haven't managed to gain much at this point but the play is smooth with no or very little flickering in the side, I'm trying to figure how I can improve my frametime without further GPU tweaking, I think I should consider myself lucky the GPU is taking it without a glitch.

Ah just read your bio, we have identical system specs. Do you experience any frame time deltas on the pico at all? (ill show a picture of what that looks like) and have you ever owned a G2. Because if the pico doesnt exhibit any of these issues that WMR has i might just sell my G2 and get one. Would you say the visual quality is sufficient? 

PS the PBO2 tuner will have great affects on your X3D. My bios recently got an update where I can do it there instead, so i dont have to use the windows program anymore. Maybe check your bios updates to see if that is also an option for you.

I had a G2 but it packed up, so I used the money from the refund to buy my first G.Skill Cl14 kit.

Not sure what you mean by frame time deltas, if it is peak in frametime, then no, in my case it is fairly stable and stays low as you can see from my screenshots, in the worst condition possible, the issues I have with this setup are not directly related to the headset but rather what it needs to run it on a PC, namely Steam VR and Virtual Desktop.

Yes I think setting up under-voltage in BIOS might be a good idea. Thanks for the suggestion.

About the Pico4 before you jump to conlusion, here are a couple of things you might want to take into consideration:

The G2 sweetspot is slightly sharper but way smaller, in terms of visuals, the Pico relies on settings and image quality changes accordingly but you have a much larger sweetspot and don't need to turn your head to see things clearly around you where with the G2 it is the only way, it helps in the cockpit.

I think Steam VR and Virtual Desktop needs to be kept as discreet as possible, I experienced a slight fogging in the middle of the screen during very low/fast phases, and it doesn't show in replays, so I turned all Virtual Desktop off and am experimenting with Steam VR so as to make sure there is nothing between the headset and the GPU...

Its battery has limit in durability but if you take breaks to spare your eyes and recharge it when you do you'll be fine, it's just a matter of taking the habit.

I also play Elite Dangerous with it and graphics are stunning, but as usual it depends on settings, if I use my O.C profile, I can notice the improvement, mostly anti-aliasing and image clarity.

Thank you for your information, I think i might sell my G2 and upgrade to a PICO after hearing this information. I have owned a G2 since they came out and have had 3 over the years as they always keep breaking. And now (admittedly isnt there fault due to amd drivers) my 7900xtx has a horrible experience while using it. I have talked to several members of the community and all have the same issue with the XTX and the G2. If possible can you please send a picture of the in game DCS frame time graph like the one i sent? just in case you don't know its right CTRL + Pause Break. Im looking forward to seeing how the pico works once i get it as the G2 has been nothing but trouble over the last few years, time for a refresh.

I'll do it when I restart, right now I'm in a lunch break, I'll PM it to you but as far as I know, my frametimes are low to moderate, nowhere near the value you posted in your screenshot.

I just restarted. I had to ask Support for setting up the full screen mirror so I can record with the overlay.

I'm trying your procedure now.

I can't get it to work or it doesn't show on screen, is there a folder if it is a screenshot where I can see the result?

It should show up inside dcs in your view, its the inbuilt performance graph. Right control plus pause break. If you are looking for screenshots they will be in your saved games folder under dcs.openbeta

I tried Right control + pause break, it doesn't work, I'll try again next time I do another test flight.

New driver's are out for AMD graphic cards . I have a RX6800 and pico 3 link . Love VR now . Got rid of my quest 2 . And went AMD . Next step 5800X3D.

I have a friend in Germany that flies co-op with me and his 7900 XT is getting 90 fps with a G2.

So, despite all of the bad VR reports, I pulled the trigger and just go a 7900 XTX.

I have tried using his approach, but no matter what I do, the 7900 XTX causes the FPS to drop to 45 fps or lower and stutters horribly when you turn your head (like it is turning on reprojection). If I switch to DCS default VR settings, I can get my fps up to 70-75 with no stuttering.

My 6900 XT will do 60-65 fps with default VR settings but will do 45-55 fps with very high quality settings including MSAAx2 without any stuttering.

I should return the 7900 XTX and save up to get a 4090. But I am stubborn. AMD knows there was a problem from the very beginning and are still "working on it". In May, their forum admin claimed they were close to a driver fix, but here it is mid-June and still no fix. It seems it is a hardware issue that can't be fixed with a driver update. But the 2d performance is through the roof: I have a TCL 49" 4k TV as a flat panel monitor which is limited to 60 fps. Unlike the 6900 XT, the 7900 XTX can run DCS with maxed out DCS graphics settings and remain locked at 60 fps with a reported theoretical frame rate of 130 to 150 fps. So, if I had a better monitor, I could probably lock at 120 fps at maxed out quality settings. If I could stand reverting back to 2D flat panel/TrackIR, the graphics quality is amazing along with the steady frame rate.

For the record, I use a Reverb G2 VR headset, but have also tried DCS with a Quest 2. Despite not using the DisplayPort, the Quest 2 looks and performs horribly as well. I tried some tweaks from YouTube that were supposed to make things right, but I saw no improvement. So, since I am too lazy to return the 7900 XTX and don't want to pay nearly double the price for a 4090, I have three options:

1. Use the 7900 XTX in 2d for amazing graphics at 4K at 60 fps but lose all the amazing effects of flying in VR.

2. Use the 7900 XTX in VR with 70-75 fps at low quality settings.

3. Revert back to the 6900 XT for VR and get really good graphics at 45-55 fps.
