--- Comment #2 from Vadim Girlin ptpzz@yandex.ru --- Please attach the output with "R600_DEBUG=sb,ps,vs", gdb backtrace might help too.
I tried some training modes and connected to some servers and so far I don't see any crashes. I never played TF2 though, so please decribe how exactly it can be reproduced, perhaps it's also specific to some map or video settings?
