Some games, like Drakengard 3, play like a dream in RPCS3 PS3 emulation; while others, like The Last of Us or, unfortunately, RDR, play like ass stank. Some classic PS3 games ie Infamous, don't play at all in emulation. If you want to play RDR on an emulator, play using the Xbox 360 one. Fairly smooth 40-60 FPS experience if your cpu is decent enough. I have it in my curated launchbox collection, and only the good stuff gets a place of honor in there.
I'll keep that in mind. Thanks.
It never occurred to me to see if there was an Xbox 360 emulator. I never owned that console and had zero interest in it since there weren't any exclusives I wanted to play.
