What's your go-to-method for upscaling old low-res games when playing on large monitors? I prefer to play windowed because full-screen feels overwhelming on a 43" screen (doesn't help that some games shit themselves and get stretched out on widescreen displays on fullscreen) but 480p games feel really underwhelming when windowed and I wish I could make it 4x or so larger without changing my display settings just to play the game. Is there any program that can magnify native Windows games, in a similar way that some emulators can blow up the pixels of the games they play (pic related)? Is mirroring the game on OBS really the best option?
