Fonts look weird at higher resolutions (1080p and above)

I suspect that D2GIBlitter::Blit is not accounting for the Half-Pixel Offset - is it? vScreenPosRect.zw has shifts by half a viewport pixel (1.0 / width) but I'm not sure this in the end results in a proper half-pixel offset. Maybe that constant + 1.0f at the end knocks things off balance.

OK, half-pixel is accounted for, I now confirmed it properly. Fonts looking squashed is something else then, perhaps they are nearest-filtered and they inevitably look bad when scaling to non-integer factors. If those draws can be detected, perhaps a "sharp bilinear" or "pixel scaling" approach can be used in the shader.

Here's an illustration of what I'm describing. This is from D2GI V2 so pinging @aleko2144 too. Compare those two screenshots at 1600x900 and 1920x1080 - at 1080p, the fonts in the list of drivers become somewhat uncomfortable to read, IMO much worse than what you would expect from a normal bilinear upscale.

(top bar is blurry not because of scaling specifically, but because of #12).
