You’re not utilizing the amdgpu driver but the radeon one as expected from Yochanan’s message.
I can suggest something to try to force using the amdgpu driver, but it is a 50/50 if you’ll boot back easily or not after that so… do as you want, if you know how to go to another TTY to type commands or if you know how to chroot your installation in case of issues… here is the tip: try to install the amdgpu-experimental package, so it will apply some modifications in the system to enable some experimental stuff (and force amdgpu if possible in the process). There might be better solution like blacklisting the radeon driver, or other manual intervention, but my tip is as simple as clicking install in Add/Remove Programs, and rebooting.
PS: I don’t know anything about your video card, didn’t research, and just made a random suggestion.
Bro thanks very much
I have tried it and it worked
but the game is working like hell
even a game of 18.6 Mb is working horrible/awful
the game the walking zombie 2 is taking very much time to open and load
and after loading I am getting only 8-10 fps
whereas in windows I used to get 30 fps second on the same hardware and on the same laptop
I have tried many games,
many low-end games, all are working very bad
if it boots to a black screen, come back on the forum with something else. in theory sudo pacman -R amdgpu-experimental from a TTY (CTRL ALT F3 from the black screen) and rebooting should be enough to get back to where you were.
