ATI users

There aren't currently any VDrift developers using ATI graphics cards on our Linux development systems, and we're interested to know how well VDrift works/performs on ATI cards.

well, i have an ati card (iFireGL 9000) n my laptop (a thinkpad t40) running linux. since i run the display at 16bpp i had to apply this patch to get vrdift running:

Code:

the comment about 16 bits not being enough is nonsense actually. the program is a lot slower than my desktop and the video card has problems when there are a lot of objects/textures but i normally get about 10-15 fps and the game is very playable.
