Scaling windowed games to full screen using state-of-the-art spatial scaling algorithms, sharpening algorithms and machine learning.




ReShade is a generic post-processing injector for games and video software developed by crosire. Imagine your favorite game with ambient occlusion, real depth of field effects, color correction and more ...
IntegerScaler is a free utility for pixel-perfect integer-ratio scaling (a.k.a. integer scaling) of games with no blur. For example, at the Full?HD (1920×1080) resolution on a 4K monitor (3840×2160), each logical pixel is displayed as a square group of four (2×2)...
