This reprojection ghosting is definitely something inside DCS engine. Oculus, SteamVR and WMR all have this ghosting. Even settings supersampling to super lower value, so low that frametime is about 2ms, and forcing motion reprojection results in ghosting. So it's definitely not CPU problem. Not to say that other games don't have that.

It happened to me as well, 3090's performance was garbage. Doing clean reinstall of Nvidia Drivers and also resetting MSI afterburner settings did the trick.
-
SteamVR supersamling affects that. Make sure that you have global 100%, per-application for dcs 100% and 1.0PD in game. See if this fixes your problem
-
I think its an issue with nvidia drivers. Rolling back drivers helps, but for 3080 is not an option...
-
I didn't believe this could happen, but the day has come. DCS runs at 90 fps in VR, doesn't have any jaggies and I can read every single thing in cockpit. These were truly wonderful times!
-
It was addressed multiple times that modern tools can not detect actual VRAM usage and display reserved ram instead. It is one of those misleading readings that don't actually affect performance at all.

Also try to measure FOV with facial interface removed. I get 20 degree better horizontal FOV with facial interface removed My only hope is that VR Cover will release some improved facial interface for g2

My first impressions on the HP Reverb G2 for DCS
VitS replied to simon3554's topic in Virtual Reality
Great, thanks. We still have hope! I am testing Quest 2 while waiting for my G2. And to get good picture with Q2 I need to bump PD all the way to 1.7, it looks like shit otherwise. -

VitS replied to simon3554's topic in Virtual Reality
Thanks for reply! Can you please also check, does picture look much better with high SteamVR SS (like 200% for example). I was expecting that with such high resolution HMD SS won't be needed. Just like on flat 1440p monitor. Difference between having 4xMSAA and having no MSAA at all is really minor. -
My first impressions on the HP Reverb G2 for DCS
VitS replied to simon3554's topic in Virtual Reality
Can you confirm that shimmering is really gone? It looks like despite high resolution we still need to use high levels of Super Sampling (like 150% steamvr ss) to have 1:1 pixel mapping in the center of the screen. -
Legacy reprojection mode is simply locking fps to 45, without trying to predict in-between frames.
-
Only CPU optimization that really works is removal of shitty RGB control software. Everything else is placebo

HP Reverb - less FPS and Hz for better experience???
VitS replied to Adam's topic in Virtual Reality
Saying "The human eye cannot detect more than 24 fps" is same as saying "in US earning more than $7.25 per hour makes no difference" ( 7.25$ minimum wage according to wiki) -
PD 2.0 with 52% SS is same as 208% SS with pd 1.0. No magic here, just leave PD at 1.0 and change SS.

Opinion requested: Upcoming Facebook account requirement for Quest 2
VitS replied to Fri13's topic in Virtual Reality
Ok. But ask yourself why they even do that? Only reason for that is to show damn targeted ads in facebook. They are not selling your data to anyone, why would they do that? It's most valuable resource they have. Either way, compared to what Google does it's just nothing. -
Opinion requested: Upcoming Facebook account requirement for Quest 2
VitS replied to Fri13's topic in Virtual Reality
Why would anyone use Facebook in 2020 for anything anyways? You can have account in FB but just never login. Don't like any posts, don't open links. FB can try to track all they want, but they just don't get any meaningful data. This facebook login scandal is blown out of proportion
