screen tearing in games.

[Ashleyyyy]

so in Ubuntu on my main pc (specs in signature) i get screen tearing even though vsync is on in the games. 

 

i already tried updating the kernel to the latest one because i have an amd gpu, and that did help with a bit of stuttering that was also occurring, but not with the tearing.

Does your game have vsnyc option enable?

Are you running those games in fullscreen?

Are you sure you don't have some global option enabled for disabling vsync? You could try to force it with this command before the game you would like to run

vblank_mode=1

If you want to enable that for a single steam game

Or just run vblank_mode=1 steam

Also make sure you are running X instead of Wayland. X is better for games.

You could also try to enable the vsync globally if that didn't work with the TearFree option in Xorg
The fastest way is to edit an Xorg amdgpu/radeon file in /etc/X11/xorg.conf.d/20-radeon.conf with that option inside, something like that

Section "Device"
	Identifier  "Radeon"
	Driver "radeon"
        Option "TearFree" "on"
EndSection

I don't know if the "Radeon" identifier is correct, maybe it is amdgpu. I don't have an amd card in linux since a lot of time honestly

You could try this identifier instead if that doesn't work, and make sure DRI3 is enabled with that option (Just try it if you need it)

 

Section "Device"
     Identifier "AMD"
     Driver "amdgpu"
     Option "DRI" "3" 
     Option "TearFree" "on"
 EndSection

(the file name doesn't matter)

If you have problems just use an editor or delete the file from a tty with CTRL+ALT+F3

Also make sure you are running X instead of Wayland. X is better for games.
