How the game runs this days with a RX580 8G any feedback for some1 who have it and play all the game ?!?!
I played the entire base game with an RX 480 8GB, though I've since upgraded to an RTX 3060.
With the Emu Scaler Enabler mod I was able to go as high as 3x resolution, without the 60 fps mod, and maintain 30 FPS in most areas, with nowhere really dropping below 20-25 fps once all the shaders for an area were compiled.
The 60 FPS mods weren't worth it, since I couldn't really get more than 35-40 FPS with them, and it introduced some graphical stuttering in game-engine cutscenes (not pre-rendered). I think this may have actually been a CPU bottleneck though, as I still get the graphical stuttering if I try to use the 60 FPS mod in Future Redeemed with my 3060. My CPU is an i5-7600K (not overclocked).
I played with Yuzu using Vulkan, though in the Pentalas region I needed to switch to OpenGL in Ryujinx (as pretty much all AMD GPU users did), as the extreme graphical glitches make that area completely unplayable with Vulkan (so I had to deal with 10-15 FPS in that area in Ryujinx). It's possible Pentalas has been fixed since then, but some of the issues I've been hearing from AMD users in Future Redeemed leads me to think not.
You may get some audio desync in pre-rendered cutscenes, but some playing with the settings should fix that up (look at the audio engine setting, and test the different settings out if you get this issue). Alternately the desync should be gone on a second watching of the cutscene (it's caused by shader compilation).
TLDR: You should be fine, and easily able to get a smooth 30 fps, but if you try the 60 FPS mod keep an eye on the actual FPS you're getting (remember, a smooth and consistent 30 FPS is better than an FPS that is higher but constantly jumps around), and if you start getting graphical stuttering drop that mod. You may need to jump emulators in the Pentalas region though (if you get to the point where there's a Colonly under a giant waterfall, then you know your in the area that had the graphical problems).
