CaptainFlint42 Posted October 28, 2022 Posted October 28, 2022 (edited) Reverb G2, and using OpenComposite and OpenXR, in the System tab in OpenXR overlay there is an "FOV Percentage" adjustment that reflects what you can physically see in the eye in the headset. This adjusts the rendered square around the headset and can be reduced somewhat in my case before I start noticing ill effects. I can get it down to 85% before I notice that there is a square image being shown. This is nice because 0.85 * 0.85 = 0.72, or basically the same as the FSR/NIS scale factor I'm currently using. So I get a performance boost because I'm rendering less pixels that I can't physically see due to headset fit limitations, but I get to keep the original quality rather than having to upscale and sharpen. In IL2 this works properly and "crops" the FOV of rendering in the headset. So I have turned off FSR and NIS upscaling, and get good images and good performance. In DCS, this is not working for me. The image shown gets smaller, but the same 100% cockpit image is "shrunk" rather than "cropped." I have tried correcting by using World Scale or Zoom but neither one of those is adjusted. I would love for this to be fixed (and many other VR improvements) but this seems like an easy one to fix since removing pixels being rendered seems like a great way to better performance for low effort.
