If you have too much money and want to sponsor a new car for Jensen Huang, thank feel free. 3080Ti coming in a month or two will be far better investment providing the same performance as 3090 for 500 $ less.

Smilodon, if you still have any issues please provide accurate description, logs and track. Especially track. We keep looking for any input from users to be sure about the fix and absence of any additional bugs.

I might, but its always a risk with older drivers. Also, 20.12.2 should not differ from JayRoc's 20.11.3 in other way than by adding Cooler Master RGB LED utility for AMD Radeon™ RX 6800XT and RX 6900XT cards, as stated in driver highlights. Edit: Exil, we could also try this: "If you would like to check out the current state of this, you can set the following environment variable: STEAMVR_MOTION_AMD to 1. Then fully exit Steam and relaunch, and opt into the SteamVR[beta]. If the env var got picked up properly, when you navigate to Video in the SteamVR desktop settings, you should have a checkbox to enable Motion Smoothing. Verify you are in the beta by checking the version number is 1.3.1 or greater." This is obviously one year old thing so it might not work at all but perhaps its worth checking.

Well which driver did you use in given comparison ?

Will try.

Not stutters, lack of smoothness. This isnt the same even though it may appear. Anyway, Exil, I use SteamVr non beta and WMR for SteamVR beta. And yes, those are my observations too. Nvidia support for VR is generally better by the looks of it and that is signified by a number of features in Control Panel like max pre-rendered frames which you can adjust. AMD does not have anything like it in Adrenalin software. The main issue we have though is related to either motion re-projection or actually motion smoothing. I've read threads on steam, regarding newest AMD and Nvidia gpus. It seems that Valve completely neglected release of RTX 3xxx / RX6800 series GPUs. One thing to do, even when returning 6800XT Exil, would be to use bug reporting tool within AMD Adrenalin and SteamVR support to report all this issues.

Motion smoothing doesnt work for me unfortunately. It still consistently sits at around 60 FPS, going down / up depending on fight. And when frametime goes up above 14 ms, motion reprojection just doesnt work (red indicator appears).

SteamVR settings menu controls motion smoothness which is not the same as reprojection. Reprojection can be changed in files or from within SteamVR Dashboard. As for smoothness, I have mine set to enable. I will try setting it to Force-always On and see if it changes anything. Ok, glad we're on the same page with warping. I saw this warping also on a gunsight pipper when flying P-51 over Normandy the other day so it can get annoying and should be removed. In any case, I have reported issues to SteamVR support and await their response. Will later look for a proper place to reach out to AMD.

So I turned on reprojection indicator in SteamVR and put FPS VR indication as close to it as possible, so all information are visible exactly as I see it in VR. I see it differently as mentioned above. First With reprojection off there is obvious lack of smoothness though image is not stuttery, its just not ... smooth. When I turn on reprojection issues appear, first the mentioned above text warping: Here is MiG-21 flying on Caucasus and Syria (I'm sorry if recording is not clear, I was using phone and trying to fly, keep controller to display data in one hand and somehow keep phone to record all that in the other. I thought of using phone to record image from lense instead of anything from desktop as that would be exactly as I experience it. For me reprojection switches off or is GPU bound at much lower frametimes than 22 ms: It even turns off at 15 ms when I tried on Syria: Except when fixed at 45 FPS / around 11 ms (green GPU bar) it is also not as smooth as when I was using RTX 3080. RTX worked much better at holding that spot and even when framerate / frametime went up or down, smoothness was unaffected. On 6800XT smoothness is noticeably reduced for me.

Asus Crosshair VII X470 motherboard, bios: 4007. I will switch PBO ON, though if I recall correctly I left it on AUTO.

Oh I thought because of DCS Ground Crew ... alright, no worries and thanks for stopping by Flappie

Will do, thank you.

I would love to climb into F-8 cockpit some day

Not on my side. On my side re-projection or at least smoothness that it is supposed to provide are not working correctly. If GPU goes below / above 45 FPS smoothness decreases noticeably. I just feel around me that picture is not smooth. I did not have similar experience with Nvidia. It held 45 FPS firm and smoothness was perfect for VR flying. But you might be right about details, I havent tried to look at it that way. Well thats why I hope Bignewy / Flappie will respond. Users should not be asked to deal with this kind of problems. I know that VR users playing with Ampere / Navi architectures are spearhead of VR crowd, but we cant replace developers and desperately need their assistance.

Reprojection works perfect with 3080 I have. Its smooth even above and below specified FPS, except when you really dive below 30 FPS which generally does not happen. But GPU usage thing is worth checking. Shame I didnt try that out last night as I've spent 5 hours testing 3080 in VR online. One thing is though that FPS VR indicated a much more stable usage of GPU than it does with Radeon.

Yes, tldr is that Radeon can be faster than Nvidia. And can reach 70 FPS despite such a high resolution. But its a matter of forcing DCS / SteamVR to use all resources properly. I still need to workout reprojection and text warping though. Perhaps its time to start making tickets for AMD / Microsoft / Valve to get their attention. Our problem is that we are niche of a niche and if we wont be loud enough nobody will care about VR folks.

Absolutely no idea mate. And I'm not sure if its 2d image itself, or the fact that DCS when you shift focus back to the App reduces the usage of GPU and CPU resources. Perhaps its a matter of incorrect resource allocation. As a matter of fact on my system there is at least a few % more that could hold 70 FPS almost locked when Alttabbed. But why on earth when I get back to DCS is usage of resources so ... bad. On flat screen GPU usage is 99 %. Is it DCS ? Is it SteamVR ? What controls resource allocation when playing DCS in VR ? I'm going to bother @Flappie and @BIGNEWY because they are the closest we can get to devs

Sooo I got you're 70 FPS with default 6800XT settings and VR preset in DCS. But there is a caveat. I can obtain those only when Alt+tab'ed and window is Out of Focus. Basically I repeated all your steps save for DDU'ing Nvidia drivers since I swap those GPUs back and forth for testing. It shouldn't make a difference as Nvidia processes dont run in the background anyway. I switched to SteamVR beta and WMR for SteamVR lkg. Not a thing changed: Although resolution scaled back, so I had to manually move the slider to 204 % to get 3160x3092 (which is my default one). But thats not a problem. Now I kept switching windows, repeating trials and than I noticed something ... I had more FPS when window was out of focus than when I clicked on DCS and was "in focus". Window "in-focus": Window Out of Focus: And FPS result: I must be crazy but why would DCS draw less resources from PC "in-focus" than "Out of Focus" ? Look at CPU usage, it drops from 5.8 % to 3.4 % and GPU usage, from 75-83 % to 55 - 60 %. This is the reason why I cant get OPs result. I dont know whether this is SteamVR issue or DCS issue but its clear that in either case, but especially "in-focus" DCS is not using system resources properly.

Describe the steps please, I'd like to follow and try all that as well to see the difference. Just for reference please also post Adrenalin settings (since I presume for benching you used ingame VR preset).

Ags has 6900XT so we can all keep comparing. I also dont think 6800XT would be that different. Less streaming processors but that is not an issue here, lack of memory bandwidth is.

This. I see exactly the same. At default resolution of G2 the GPU usage is inconsistent and fluctuates. I did OC my 6800XT to 2650 Mhz, turned on SAM, put Power Limit at 115 % and increased VRAM clocks to 2120 Mhz. Gains in DCS were minuscule, I got closer to 60 FPS. But nowhere near JayRocks 70 FPS.

Another one attached. And no, I disabled Nvidia share. Didnt change a thing. list.txt

Since when did ED claim to be using DLSS and Nvidia Raytracing ? Those are proprietary technologies and so far DCS never supported anything like that. Since DCS is going to change API to Vulkan, its likely that we will get some day Khronos open ray tracing stuff as well. And OpenXR support. Anyway, I quickly swapped back to 3080. My stutters are back but they can be cured with simple alt+tab. However reprojection works flawlessly on RTX 3080 and it holds those 45 FPS much better than 6800XT. And even going below / above it does not affect smoothness. Re-projection must have some issues with AMD. Second thing is that text warping I had in DCS settings / controls with 6800XT is also gone.

Alright, here it comes. Be advised, any time I ALT+TAB it gets fixed and stutters stop. Its bizarre. I hope this catches it before the stop as I have to alt+tab every time to get those lists. list.txt list2.txt list3.txt list4.txt
