Not sure which is weirder, that Rockstar would put effort into making an official goofy zombie mod or remembering that they used to do singleplayer expansions :thinking-about-it:
It's peak 2010's zeitgeist either way.
Since I don't trust my rig to be able to handle upscaling in Xenia, I'm stuck with the native resolution and oof, the 7th gen might have been one of the nastiest looking console generations out there outside of early 3D on the PS1/N64/Saturn.
Something about relatively advanced effects being rendered in horrible blotchy sub 720p resolution and the unsteady <30FPS framerates is... not good.
If your PC is better than my RX6600 and Ryzen 5 3600, you can try it out yourself with better results.
From the looks of it, RDR on RPCS3 requires a beefy CPU and mine is only B tier in the official RPCS3 tier list. I might give it a shot though, since RPCS3 is far nicer to actually use than Xenia which still feels pretty primitive.
