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.
If it can emulate PS4, it'll handle Switch like a breeze. Your specs are overkill for that level. Switch runs on what is effectively potato hardware compared to most new entry level PCs and it's a couple generations behind consoles.
That said, I unironicly think it's the best system ever built.
I don't think anyone is emulating PS4 in any meaningful sense currently- AFAIK PS4 emulation only runs homebrew and maybe 2D indie games at the moment.
The Xbox 360 is even farther behind than the Switch and it's not trivial to run on my system. Then again, Switch emulation has much more interest and work put into it, so it may even out
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
