All you need is to put +mat_forcehardwaresync 0 and it fixes it. You may also want to put -dxlevel 70 as it helps alot. HOWEVER, some servers require your dx level to be 80.00000, but not many. After you have run the game using the the advanced launch options, YOU MUST REMOVE THEM! If you do not, all of your ingame settings will reset to how it likes.
Thanks to that command I can play css even on my netbook. INTEL 9xx SOLDIERS SANS FRONTIERS
