I would recommend using a tool - don’t rely on your operating system or the game for upscaling. Lossless scaling works incredibly well for this. I’m currently playing FTL (720p pixel art game) on my 1440p screen and it looks magnificent with this tool set to integer scaling. Razor-sharp pixels instead of the blurry, mushy ones that it suffers from with its built-in upscaling.
None of this makes any sense with 3D games though, of course. You have to be blind to play 3D games at 720p on a modern display.
