This one is for the retro enthusiasts. Integer scaling is mathematically "lossless" in the truest sense. If you have a 1080p screen and a 540p game, IntegerScaler maps one logical pixel to four physical pixels (2x2). The result is sharp, chunky, and exactly like playing on a CRT or a Game Boy Advance screen.
Because it is open source, the community has ported AMD’s FSR 1.0 (which does not require ML cores) into Magpie. It isn't as good as DLSS, but on a low-end GPU, turning 540p into 1080p with Magpie can mean the difference between 25fps and 60fps. lossless scaling gratis
After all, a pixel is just a pixel. It should not cost a dime to make it fit your screen. This one is for the retro enthusiasts
