Issues with screen tearing during gameplay.
Issues with screen tearing during gameplay.
On your main PC running Ubuntu with an AMD GPU, you experience screen tearing despite using VSync in games. Updating the kernel helped slightly with some stuttering but not the tearing issue.
Verify if a global setting is active that turns off VSync. Consider using the command before launching the desired game to set vblank_mode=1. If this doesn't work, try enabling it in your Steam installation or globally with TearFree in Xorg. The quickest method involves modifying an Xorg amdgpu/radeon configuration file located at /etc/X11/xorg.conf.d/20-radeon.conf and adding the specified option. You might need to check if "Radeon" is the right identifier—perhaps it should be "amdgpu"—and ensure DRI3 is enabled with that setting. If issues persist, use an editor or remove the file via CTRL+ALT+F3. Remember, X is generally more suitable for gaming.
