Is a rx 6800xt in VR workable in DCS World ?

[Flying_Egg]

 

Hi all,

I am a little lost here and I would appreciate a little  info.

I just purchased a new 6800xt thinking it would work great in DCS since the digital combat simulator website states that the recommended gpu for DCS in VR for 2.8 is a “Discrete video card NVIDIA GeForce GTX 1080 / AMD Radeon RX VEGA 64 or better “ But After reading many of the posts on here I am not so sure.

 

From reading posts on this forum, it seems there are many add ons or other apps to help bring up the FPS but most comments seem to say , they work well for Nvidia but not so well with AMD

 

I have only really seen two Members on here who say they have AMD in VR running great. One of which is Ted who is still active in the forum but I see has now shifted from a 6900xt to the 4080. Maybe there are more players using AMD with good results but they just aren't posting?

I also am seeing other members who are saying since the new 2.8 their VR frame rate has become unacceptable for them to the point of them discontinuing play.

 

So Is there anyone on here in VR running off a Rx 6800xt with acceptable performance not on steam? Is it any better on Steam?

 

Are there actually other helpful apps to bring AMD performance up to acceptable levels.

 

Thanks in advance

Both the steam and non steam versions of the game are identical.  It just changes where you launch and update the game from.

As of the last update you do have a choice between which VR API you use, steams (openvr?) or OpenXR (native WMR).  Most believe openxr is superior regardless of GPU, but YMMV.

 

Been running a 6800xt for the last 2 years now.  It works ok.  I get between 40-60fps avg pending on what module, map, and units are on the screen.

YMMV pending your DCS settings and CPU's ability to feed it.  

This may all change with the upcoming multi-thread update (maybe this year??? who knows for sure).

Right now, Nvidia cards and drivers work better in VR, not just DCS.  I've used a 4080 and a 1080ti and both gave a better experience across VR.   The good news (for you) is a 6800xt with the current drivers is better then the new 7900xt with it's current drivers in VR.  The new gen AMD stuff has been a huge let down on the VR front.

I run a X570 gamer x MB with a Ryzen 9 3950x 16 core 64GB mem with VR I am just now (I'm old) getting to Underclocking My Red Devil RX6900xt I am on the Stable Version DCS Stand Alone NOT STEAM I run WMR settings 90 FPS set for Quality Open xr Developers Toolkit with Motion Reprojection Always OFF on Custom Settings with a Custom Render Scale of 50% for (HP G2 VR headset) Then in the Open XR Toolkit Companion Program is set up for Turbo and Open Companion to stop Steam VR.

I have been getting 30 to 45 FPS with Motion Reprojection Always on BUT tonight after the above setup with the Underclocking on the GPU and Turbo on in Open XR Toolkit Companion My FPS has jumped to 60 to 70 in my Only before 30 to 45 FPS Missions and my 45 FPS Missions to 70 to 90 FPS in my other missions WOW I am late to the Game doing this but Make sure you underclock the GPU AMD cards work good this way. Do Not think it will hurt the card it will not. Good Videos on YouTube on how to do it. I and running on HIGH settings in DCS and all of the sliders are set to about 80% full right side. 

I can't Show Open XR Toolkit Composite Menu because it is only viewable in the VR headset but under Performance is Turbo Mode ON or OFF it is ON

Thank you Strong.

Have you  under clocked your  6800xt?  Getting a better experience with a 1080ti is worrisome.  With DLSS "coming " to DCS that would be a game changer since that the increase will only benefit Nvidia cards and further diminishes AMD (does FSR work in here at all.)   I doubt Radeon Super Resolution (RSR) is going to be a player anytime soon so that won't help.   I was thinking about picking up a 7900 xt but it's over priced for the value, and I just refuse to pay soooo much for the 4080 and the 7900xtx on principle alone.

Thank you DishDoggie,

 

 I am planning on under clocking both my cpu and my Card.  It reduces both the heat problems and allows for a little more performance at the same time. the 7900x has a tendency to run a little hot.  Looks like you got a decent increase with your new settings.Are you running SAM or does that even help in VR ? How much does your  Custom Render Scale of 50%  reduce your images?  Do people with 3080's have this much trouble getting good frame rates.  Are you getting results comparable to what a 3080 would get.

SAM sorry don't know what that is so no. 50% on the Custom Render scale I run and to me it has a Small amount of reduced Image but not that bad and the only reason I do that is because I want to run Shadows On (BIG FPS KILLER) and only 2 of the 3 on because I love the look in the Huey with Shadows in the Cockpit and low to the ground. With Shadows on I get 40 to 47 FPS but only at 50%. With Shadows off and 100% I am still at 50 to 60 and 60 to 90 I am still testing things. One other thing I did because I want to record my VR screen is to manually set my Screen resolution in DCS to 2160x2160 using the one eye for VR with the Vr Mask Removed/off by editing the Shader file for the VR desktop Screen in the core DCS install.

Best of luck to you.

I'm undervolting, which actually increases performance.  Jays2cents has a good video on how to do this.

 

Apologies if I wasn't clear, the 6800 XT is absolutely a better performer in VR then a 1080 ti for DCS.  However, the drivers (motion smoothing/reprojection) is better for Nvidia, and just generically speaking I have found that Nvidia cards support VR better which includes the 1080 ti (even though it will be significantly slower then a 6800 XT).

Hi, Yes the more I am reading the more Nvidia seems to have over AMD in 4K and VR.   I have a couple of days left to return this 6800xt. You probably have already set your settings to what TED in here has suggested with setting lower frame limits.  and Doggie seems to be getting some decent numbers. I was already thinking of upping to a 6900 or even a 6950xt.  I am also looking at used 3080's 3080ti's and even 3090's since they are under or around the same prince as  6900/6950's  I don't think the new lower end 7000's series will do any better than the 7900's or the 6900's or even the 3080ti in VR .  I've been sitting on this new build now since Nov. of last year gathering dust with no GPU  lol. I think6900 series GPU prices will drop a little more soon, and I can take another look and also keep my on some of the used Nvidias. Luckily/Unluckily I am too busy right now to be playing as it is, but my current job is coming to an end and I will go working part time and become  semi- retarded  I upgraded to the AM5 platform knowing I will probably upgrade from the 7600x to the 7800x3d a little while after it comes out.  

 

Do you play multipler on DCS or solo with your 6800xt frame rates?

I'm currently getting pretty good performance with my 3080ti, GPU frametimes around 13ms on Syria. Running 60hz on the G2 so really smooth.

I didn't understand you as clear as I thought. If you wonder if you should go with a Nvidia over the AMD Card I thought it was a done deal, I would go with the 3090 after having the AMD I like it it is a good card but when I did my build upgrade you could not find a 3090. lol I picked a bad time to upgrade. If you can and still have the ability to do so. It would be a better pick. Sorry I thought the AMD was all you had. Still Whatever you do Best of Luck.

There really isn't much difference between a 6900, 6950, and 6800 xt. Talking maybe 5% or best case 20% better. The 12Gb 3080 got nearly identical performance to the 3080ti.

 

I'm running openxr with motion smoothing off.  PD set to 1 in game and 100% in open XR tools.  No frame limiters either, just the undervolt and a slight bump in GPU freq.  I am running with SAM on, I did briefly try a 7900 and SAM actually reduced frames (I returned the 7900 because the performance was worse then my 6800xt).  I've tried reducing render scale/PD and I immediately notice the difference in cockpit.

 

I got the 6800XT because that's all that was available (purchased 2 years ago).  I would take a 3080 12gb, ti, or 3090 (pending the price isn't outrageous) over the AMD cards any day.

First of all, to be clear I'm the owner of the RTX 3080.

From my experience, all this fuzz about Nvidia or AMD is exaggerated. So I could tell you your 6800XT is almost the same performance as my 3080.
In practice, there is no difference at all. The real bottleneck is not GPU or CPU. The real bottleneck in DCS is the core engine itself. Without real changes, there will be no noticeable progress.
My 3080 sometime works great but sometimes has all these problems that they claim are only experiencing with AMD. This is simply not true. Problems I experienced have only at DCS everything else works perfectly.

Changing your 6800XT for something similar is not worth it. Change it right now for something better like 4080/7900XTX is questionable.
That will be great uplift but not worth that much you need to invest in this. AMD and Nvidia's new generation is highly overpriced so the last generation is still better value.
In general. I'm talking about the value, not performance.

Right now your 6800XT is good for waiting a little bit longer when offer and demand will stabilize the GPU market like it was with CPU for example. AMD is a good quality card but if the price is the same as Nvidia I will buy Nvidia. If the price difference is noticeable no doubt I will buy in this case AMD. For example, if we compare it with MSRP prices if you want the best beast 4090 is worth the price. If you want a budget more friendly beast then 7900XTX is a better value than 4080. I will buy 7900XTX over 4080 no doubt.
7900XT is a different story because the 4070Ti is a better value even is slightly lower performance but not that much so the 4070Ti always before 7900XT even right now maybe the 3090Ti /6950XT is a better value same as all other models.

Be patient, till the summer GPU market will be stabilized, and then see what is the best option for you with new prices relation.

[Flying_Egg]

DishDoggie, No, you read it correctly. I jactually bought the 6800xt but I still have a day or two to take it back. The box is still actually unopened. If the play-ability would have been good enough , i was thinking on keeping it, but I might as well save the cost of this card and get something with better performance in VR and if DLSS is "coming down the road", that is just one more thing to go for Nvidia. Maybe I will pick up a used 3090 for just a few more hundred than what the 6800xt cost me and or wait until summer for bigger cost drops (good luck with the manufacturers now cutting out the scalpers to make the money themselves lol. Or maybe even just pick up an old crappy card so the machine has a gpu and wait till summer.

I haven't even started playing DCS yet so I don't really know how much I am handicapping myself with the card choice. I'd use the card I have in my other machine, except it is an older amd chip with no onboard graphics, and I still need that machine for business.

[Flying_Egg]

RE the current 7900xt , I am only hearing poor results with it in VR. If they can't get the drivers working better then its a waste, and it is definitely overpriced for the amount of increased performance dollar for dollar. I understand there has been an increase in manufacturing cost, but sheer greed is hitting Nvidia and AMD.

If I find I love DCS and can't live without it then I might go ahead and buy a 4090. Some of the reviews I have seen make it look enticing, but I am just not happy with the manufacturers right now. Their attitude seems to be FU sit down and shut up lol And yeah, the prices are still way to high for these cards, but it looks like that may be the norm.

[Flying_Egg]

Wormeaten,

Thank you. I seem to be reading a lot of how the DSC engine needs changes. I am hoping the 7800x3d will make a difference in DCS world. We'll have to see. If DSC adds more features but doesn't fix the engine I think that may become a problem and not such great marketing. There is a youtube vid out there with someone with a new 4090 were it looks like it is handling things very well.... . I will put on my Halloween Dr. costume and act like I have a lot of patients :)

Thanks again
