VR Hardware Benchmark late 2020 - Ryzen 2000/5000 - 1080ti vs 3080 vs 6800XT

Recommended Posts

So I have changed:

- Default SteamVR app motion reprojection mode to SteamVR perr-app setting

- Force DX11 mode - ON

 

Motion Reprojection works MUCH better for me and its actually holding to 45 FPS at 14-15 ms. There are however still frequent instances when FPS goes up to 50-60 and I see reprojection indicators changing (switching constantly Blue - Red, so GPU / CPU bound - Off), but smoothing also seems to be working and so overall experience is like Nvidia.

On the other hand it did not cure on my side issue like text warping. There is also visible shimmering on power lines, cockpit edges (MiG-21 most noticeable on gunsight frame) and even a bit on fps VR window. 

 

I cranked up settings in game, set few different things in driver and overclocked GPU. Now I will take it online and see how it compares to my yesterday experience with Nvidia.

Cool! Good to hear! 

So you set motion reprojection on auto or motion vector in wmr and in steamvr you set it to per app? Do I understand that correctly? 

 

If so, you could try to set it on motion vector as this should lock it to 45fps and you should not see the jumps up to 50-60fps.

Did you notice blurrier overall image compared to forcedx11mode off?

I just set motion reprojection to SteamVR perr-app setting in OpenVRSettingsUX.exe (can be found in Steam folder).

 

I can try changing it to Motion Vector.

No, not particularly. But than again, I wear glasses and until my lenses from VROptician arrive, I am not the best judge of how blurry or not things are.

I just hope we get a fix real soon, because I`m already considering returning this pos card.

Well, card is not pos, it has performance in it. It's software that sucks. I went with indicated above config online. Well, its playable but there are still reprojection errors related to warping (text, gunsight) and shadows flickering. And reprojection is Valve concern if I'm not mistaken.

@Habu_69 No. There are some issues with AMD RX6000 and WMR. But there are easy work arounds and the AMD´s are way faster (in DCS!).

If you play a lot of other games, the RTX might be the better choice. But again it depends on usercase.

 

My current settings for MP:

 

SteamVR non Beta

WMR for SteamVR Beta

Steam SS 80% (for HP G2)

DCS 1.2

with no MSAA

Steam motion smoothing to Auto

 

I get pretty much all of the time 45fps with reprojection on busy servers.

DCS Supersampling to 1.2 increases the sharpness a lot and since i set it there, i have no issues with warped texts (just some times the chat) but no artefacts

in the cockpit or the world.

Maybe interesting for some, because I have tested the 3080, 6900XT and the 3090 with DCS too. My 3080 kept crashing, so I was looking for an alternative. I was most excited about the 6900XT, but I have to say that when I tested it, I was really disappointed. My own benchmarks weren't really much better than my 3080 and the "feel" (and fps, ms,..) in DCS was the same. The card that ended up staying in my PC is the 3090. First DCS run with it and I was grinning like a kid. It's interesting that it might just be a driver problem, but for now I'm really happy with the 3090. Even if it is overpriced.

Having followed all this testing, results appear to indicate that for now with current drivers and software, for DCS in VR, the RTX 3080 performs consistently better than 6800XT. Right?

Hard to tell. The raw data indicates that Amd is the better card. If you don't use motion smoothing and looking for 90 fps I would recommend amd. 

If you need motion smoothing (most likely in VR), then I would maybe wait. There are issues right now. They could possibly be fixed with the next driver update or maybe never. We don't know yet. 

If it's gonna be fixed I am pretty sure, that the 6800xt will be one of the best cards you will find for DCS.

Jatrock, what's the reason behind SS at 80% and PD at 1.2?  I thought that leaving PD at 1 and manipulating the Steam SS was the better way to tune performance/visuals?

Thats what people say who havent tried different settings. You shouldnt go with DCS SS below 1.0. But the SS of DCS is sharper than Steam SS...but is heavier on your hardware.

With my Odyssey i went for Steam SS 150% and DCS SS 1.5 which gave me a very good clarity. I could read read all gauges in the cockpit from my normal seated position.

 

The 80% SS on Steam is just for the G2. With the G2 not 100% is the native resolution but 50%. So the 80% would be the 150% on the Odyssey.

If that makes sense?

 

Try for yourself and find settings that suit you and your maschine.

Do you think that it is the lack of VRAM on the 3080 that is the issue?

I am not really sure if it was a VRAM problem, but with the 6900XT and the 3090 the problems were gone immediately. Multiplayer now works without problems and most importantly I am no longer afraid to open the f10 map. With the 3080 I had several problems (reverb bluescreens, SteamVR crashes, ...) as discussed in the other thread. In my opinion, something strange was going on with the VRAM usage of the 3080. But maybe it's just a driver problem or something else.

Please read the difference of frametimes and frames per seconds.

 

But as stated in other threads nvidia improved their VR experience with 460.79 a lot. 

 

I tried to find the difference but most reference FPs and refresh rate. I was trying to understand why people refer to frame time. can you explain or giver me a link.

 

thanks

Because frametime matters most in VR.
To maintain 90fps you need to be in the land This is impossible even for the most beefy hardware. So the next goal becomes to be under 22ms to have a smooth experience with ASW/Motion Smoothing.
Frametimes are the time that the cpu uses to prepare a frame for the GPU and the time that the GPU uses to render it.
1000 milliseconds/90 frames = 11.2 milliseconds.

Thank you for the explanation!!!! I’m frame time is 20-25 when I happen to look for it earlier. I have spend hours already trying to figure out what my next hardware setup should be. This tread has helped a lot.
