Really?!? Oh man, this means Ati sucks big time. For them to provide drivers which don't even support the main functions of that card the driver is meant for is shocking to me, I thought they were professionals. This is probably why all the L4D players on ubuntu I see use Nvidia, must truly have better support...o dang it ( smash smash smash ) Just to be sure, where can I find information on what the Ati Drivers actually do support? You seem very knowledgeable in the matter, please provide me with some references :) I don't believe the ati website has the information ( or at least I can't find/locate it, I've searched for quite some time) Plus: does this mean there is no workaround for Ati cards for L4D? ( in terms of whats missing in the driver )
