To hide timewarp glitch overflowing the FOV with upscaling. Maybe SSAA optimization
If fov is 90° upscale image to 100 or 110 when timewarp activates for put glitch outside the fov
I mean the black border of the fov when you are moving the head fast
Is it possible to upscale to 2x as fake downsampling for help with the problem of the distortion for the lens?
I mean, about 1.8x does not give improvements to increase even more the SSAA, but is important for to read text clearly, minimum 1.5x
Today there are better algorythms than bicubic. DLSS gives worst results with RTX 2.*** series in a few games than standard upscaling
