Fixed foveated rendering cull (elimination) #15

This is not a bug request, this is a feature request/question. I have been using OpenXR (native) with iRacing, and the thing that improved the performance the most for me was having Fixed Foveated Rendering CULL, which effectivelly eliminates part of the image from rendering. I can safely eliminate around 20% of rendering without actually losing anything from my view (PSVR2). Turning the same 20% down in resolution (to 1/16) does not have the same effect.

I would like to know if it would be possible to have a similar setting in this tool (cull). I read that it uses Nvidia Variable Rate Shading, but I'm uncertain cull is achievable. What do you think?

You can reduce the rendered FOV in SteamVR, which effectively accomplishes this.
