I suspect you are confusing OXR (OpenXR DevTool) render scale (which I have set 1at 100% and I do not touch it) and OXRTK (OpenXR ToolKit) Resolution Override. I think the original value of OXRTK Resolution Override was around 4100 before I modified it the first time, but I’m not sure. This is more than OXR 100% resolution, if I understand correctly, this is because of this figure is taken before the barrel distortion correction (so not the final image), so it needs to be higher resolution to retain definition in the center of the image.
Normally there are optimal multipliers that give the least artifacts when upsampling or downsampling an image. Because I don’t know the original resolution in OXRTK and I don’t want to reset all settings to find out, I’m asking what it is. Then, this needs to be multiplied by something: ideally 200% but that’s too much to handle, even for 4090. So my second question is what would be the best multipliers to try for least artifacts…
