I've been pondering on how to get vsync on 800x600 resolutions for my HL mods? By editing the xorg.conf I got the Hertzs right (100), the only thing missing is vsync. For some reason I can't really play without it, just get's annoying..

Shouldn't this do the trick?
# 800x600 @ 100hz
Modeline "800x600@100" 71.71 800 832 1104 1136 600 610 620 631  +vsync
It doesn't seem to work in the game, since I definitely can recognize clipping on walls etc. when moving?
