I have a strange problem with Garry's Mod.
There's a delay between my mouse/keyboard movement and the real movement in-game.
I can fix this problem on other Source Games with the gl_finish command, but Garry's Mod doesn't offer support for it.
How I can force the GPU to sync with the CPU?
I don't have this problem with integrated MESA drivers provived by X.Org.
