--- Comment #196 from Evan Goers megatog615@gmail.com 2010-10-10 02:56:51 CDT --- One more thing to note is that despite what everyone is saying, it appears to happen much more often on ATI. When I switched from an NVIDIA Geforce 8800GTS to an ATI Radeon HD 5770, Counter Strike Source immediately began crashing at random(when it never did on NVIDIA). I had not updated or otherwise changed versions of wine after installing the new card.
