Cthulhus Posted June 19, 2021 Share Posted June 19, 2021 Hello, I have a strange bug on DCS VR mode. I'll try to explain it ... First, I have this PC : I9-9900k, 32 Gig of Ram and RTX 2080ti, Win10 Pro. I have 3 VR headset : HTC Vive Pro, G2 and Vive Pro 2. Same issue on all VR helmet. I have something like lags/judder. I have this issue from the game menu to the in game/in the plane, anywhere. (Setting the game in low setting don't do anything ! (so it's not a PC issue). Without VR all is fine and can play the game at 150 fps on high setting. And the tricky part : If I set the game is out of focus, (with the red indication : Out of focus) all become fine in the VR headset ! (but ... as the game is out of focus, I can't use it ...) I have the issue since 2/3 months and I found a partial fix but now not longer working. The trick was to switch from Beta to Normal version of Steam VR. (I had to switch each time I wanted to play. But now, it's not working anymore...) Any idea ? I tried : • Full re-installation • Steam VR re installation / full reset. • Deleted the game data (settings etc) • Updated the GPU driver • Use other VR headset I don't try yet : • Windows reinstall Thanks Specs: Win10 64bits Pro, Intel i9-9900K | 32Go | RTX 2080 Ti | M.2 SSD 850go x2 Hardware: HTC Vive Pro + X56 Maps : Normandy + Assets | Gulf | Nevada DCS Modules: FC3 | UH-1H | Mi-8MTV2 | A-10C | F/A-18C | Ka-50 | SuperCarrier | F-14A/B | F-5E | F-86F Sabre | MiG-15bis | Mig-19 | MiG-21bis | AV-8B | Fw 190 D-9 | SA342 | P-51D | Bf 109 K-4 | Spitfire LF Mk.

Convexrook Posted June 19, 2021 Share Posted June 19, 2021 it is the 9900K, I had the same issue and it wasn't resolved until I tried a different CPU. After that I upgraded to 11900K Sorry but re-installing windows won't fix it. Link to comment Share on other sites More sharing options...
Cthulhus Posted June 19, 2021 Author Share Posted June 19, 2021 (edited) Ouch, hope I'll found a solution (or ED), the 11900K is expensive : 689.99€ on my local store... and their is no indication that i9900k isn't compatible in VR.

Cthulhus Posted June 19, 2021 Author Share Posted June 19, 2021 realistic with your settings? It's not a perf issue, I still have the bug from the ingame main menu with low settings.

speed-of-heat Posted June 19, 2021 Share Posted June 19, 2021 Hardware-accelerated GPU Scheduler do you have motion smoothing enabled correctly? and if its not a perf issue, why did you think a new cpu would fix it?

Convexrook Posted June 19, 2021 Share Posted June 19, 2021 (edited) Like I said, it was a CPU microcode issue with my 9900K the 9700K is fine. This I have tested on my other 2 systems 8700K 6600k and my wife's computer 9700K. To be honest it could be a multitude of issues, I was giving my experience with the issue and my solution.

Cthulhus Posted June 19, 2021 Author Share Posted June 19, 2021 I disabled Hardware-accelerated GPU Scheduler and I still have the issue... I contacted the support and they don't know what's is wrong... I have this only with DCS, I play lot of VR games and no issues...

I don't think it's a settings issues, for example, I have the same issue if I set the game in extremely low settings.

I'll install a temporary Windows 10 on another drive to see if it change something. The next Windows 11 will be free. I'll make the update and see... Or maybe that will be fix when ED will move on Vulkan. Something broke my VR and maybe that will be fixed alone with an update of something... But now I can't use DCS ...
