First of all, I know xWayland already does this when in a Wayland session but RPCS3 (PS3 emulator) runs disgustingly bad inside Wayland on my PC, and during an Xorg session the same emulator runs perfectly, and it’s not a FPS issue or framerate, it is a problem that any game is simply unplayable because it suddenly gives stutters that do not exist in Xorg.
KDE Plasma honestly feels extremely buggy and slow on Xorg and so I don’t want to use Xorg, I would like to use Wayland and not have to log into an Xorg session every time I want to use RPCS3.
Now, I am using KDE Plasma 5.27 with Wayland and using Nvidia proprietary drivers (515).
(If Linux4Noobs existed on Lemmy I would have posted this there)
QT_QPA_PLATFORM=xcb is the environment variable you’re looking for, got that from https://wiki.archlinux.org/title/wayland#GUI_libraries
In fact you are right, although unfortunately it didn’t help, and I have a doubt, how can you find so quickly the information of commands or specific variables that solve something?
I mean, of course, before asking in a community I try to investigate on my own but many times I don’t find anything useful and that’s why I have to ask.
I have had to force xwayland a number of times, so, I was familiar with it beforehand, it took me forever to find the first time!
In this case, you’re going to want to post a bug report to the rpcs3 issue tracker, this sounds like something they need to resolve on their end.
