RPCS3 is running fairly well in my experience. It can be a bit hit or miss on what games work, but a lot of the most popular games run fine. There’s even upscaling to 4K and getting games to run a 60 FPS that originally only did 30.
Poke around on here and see if what you’re looking for is playable. You’ll even find workarounds and optimizations for specific games (MGS4 is a big one for this)
