Almost all games look blurry and pixelated on RPCS3

Hello guys, If a game has a 720p default resolution (almost all games), it looks pretty pixelated/blurry on my monitor (1080p) no matter what I do (set resolution scale to 300% or turn on FSR upscaling). If a game is default 1080p everything looks pretty.

Is there any way to make 720p games look as good as 1080p games? Thanks
