I completed the Xbox 360 version of Read Dead Redemption on Xenia Canary some months back with the only enhancements being a 60 FPS unlock patch (I don't think my rig ever really hit 60, in empty wilderness scenes I got around 40-55 FPS and in towns and heavy combat I got maybe 22-30) as well as some antialiasing and smoothing filters applied to hide jaggies since I didn't think my RX 6600 could've handled resolution upscaling.
I still have Undead Nightmare to beat, but the PS4 and Switch versions got announced while I was getting to the end of the main game, and now that they're out I'm wondering if I should try Switch emulation for the DLC.
I did some quick googling and it seems emulating the Switch version on RyujinX has better performance visuals and less graphics glitches than Xbox 360 emulation, but I'm not sure if my Ryzen 5 5600 and RX 6600 are enough to make it a better option than the 720p with unstable FPS and lighting glitches you get on Xenia.
Huh, didn't know the switch was that powerful! Never mind then I guess.
The Switch is very emulatable at this moment, which annoys Nintendo to no end
It's the PS4 that's still very much in its infancy when it comes to emulation, but it'll probably be more and more of a thing in the coming years
