Edit: Video removed.
Thank you for the quick reply!
This is my currently unlisted test video that I am sharing with you. I am editing it as of now.
Most of the time I am getting 90Hz in my HMD but in the video it is obvious to me when it slips back to 45Hz. I am OK with the performance in this video but:
I would very much like to know your input on why I get pop in textures and very bad shimmering whilst flying along the beach looking at the thin line of wooden docks made for small fishing boats etc.
In the video at 22:38 you can see a building that is being constructed from bottom to top in real time. Very strange!
This is raw footage from a cropped 'window capture' to hide the VR lenses shape. I am also using the default resolution in OpenXR which says (something close to) 3100 x 3100 I believe. Even though the Reverb G2 is a 2160 x 2160 resolution HMD. I don't understand that. I am not using any OpenXR post processing.
DCS pixel density is set to 1.0.
Information as copied from the video description:
Testing OpenXR CAS & Turbo Mode, Over The Landing Beaches In a Reverb G2 V2 Also testing the new Nvidia AV1 Live Stream Encoder with OBS at 2560x1440p (16:9) with Window Capture and custom cropped settings. Constant Bitrate of 18Mbps. OpenXR Turbo: on. With CAS sharpening at 100%.
DCS: High & Ultra settings. All DCS in game AA settings switched off. If the frame rate looks higher than 45fps in the video, then the frames are 90fps in my HMD. 5/22/2023

PS.
I have heard that in IL-2 GB's. People have had good results in VR, setting their Texture Filtering - LOD bias to -500 in the Nvidia Profile Inspector.
I am yet to try this in DCS.
My Nvidia Profile Inspector 2.3.0.13 version seems to have removed all BAR settings. But I remember forcing it on a couple of years ago. New Drivers maybe?
I am also running no Anti Aliasing in DCS. So maybe a simple OpenXR upscale of 10 to 20% would be enough for the shimmering? Instead of the DCS 'MSAA x 2' switched on. It is very heavy on my performance.
