Lee Dove Posted October 23, 2023 Posted October 23, 2023 (edited) I had a problem in early 2.8 MT with running VR. It would become CPU bound and run at 5-6 fps. In ST it would run fine 60 FPS. I thought it had been fixed in later 2.8 patches but I am not sure as I used ST a lot of the time. In 2.9 (MT) I get the same problem - CPU bound in VR. In 2d I get 200+ fps and in VR I get 6. In ST 2.9 I get 90fps. Any ideas ? Edited October 23, 2023 by Lee Dove

wakeup Posted October 23, 2023 Posted October 23, 2023 I would start with reducing the pixel density option in the VR tab down to 1.0 and re-testing.

Thanks - I reduced the PD and now works. I can get the PD up to approx. 1.3 but above that the problem returns. Strange that I can run 1.8 and higher cloud settings in ST though. In ST I seem to be GPU/CPU bound with both working but in MT it is solid CPU bound and the GPU has plenty of capacity left. It would seem that FD have moved a lot of rendering load to a single thread and now overload it in MT. Probably gone a bit to far with the load redistribution. Edited October 24, 2023 by Lee Dove
Lee Dove Posted October 27, 2023 Author Posted October 27, 2023 This has now returned . Even with the reduce settings MT is 10 fps and ST 45 fps.

My advice for now, turn pixel density to 1.0 and disable DSR and test for frame rate with power setting change. Forum rules - DCS Crashing?

My adivce for now, turn pixel density to 1.0 and disable DSR and test for frame rate. I reduced the PD down to 1.0 as per an earlier post. I was getting the same performance in ST and MT. Today after 1 mission I loaded and MT was down to 7-10 fps. I tried in ST and it was back to 45 fps. I will try with DSR disabled. Update: I disabled DSR and it seemed to help. I will keep track over the next few days. Edited October 27, 2023 by Lee Dove
ED Team BIGNEWY Posted October 27, 2023 ED Team Posted October 27, 2023 power setting in NVIDIA control panel is important also thanks and good luck Forum rules - DCS Crashing?

Lee Dove Posted November 14, 2023 Author Posted November 14, 2023 The issues seems to have been with the Oculus App. I have moved to Virtual Desktop VR and now get great performance. I think the Occ. App and the DCS rendering thread are fighting for the same processor. 1

The quest will run without the occulus app , both 2 and 3 if you use Virtual Desktop. The only limitation is that it has to use a wireless link not the wired. I get better performance from VD wireless compared to Occulus wired Link. In fact when I got my Quest 3 I had issues with the Link which made me try VD. Best thing I ever did 1
