The previous implementation of HPO adds an offset on vertex position. It doesn't always work beside it moves the rendering window. The new implementation will add a texture offset so that instead to sample the middle of the GS texel, we will sample the middle of the real texture texel. It must be manually enabled with * UserHacks_HalfPixelOffset_New = 1 (keep a small offset as intended by GS effect) * UserHacks_HalfPixelOffset_New = 2 (no offset) v2: always apply a 0.5 offset in case of float coordinates (Tales of Abyss) Might break other games but few of them uses float coordinates to read back the target
