First off, this is a semi cross-post from the AMD Game forums: http://forums.amd.com/game/messageview.cfm?catid=279&threadid=153525&enterthread=y
There has been an ongoing series of problems with the Catalyst 11 series drivers and the OpenGL based game City of Heroes, generally starting for most players around Catalyst 11.5, but with other players expirencing problems across Catalyst 11.3 and 11.4.
I've been able to reproduce many of the reported stability problems under Linux with Transgaming's Game Tree Linux Translation layer, indicating that the problem seems to be with the driver itself.
As of right now the ongoing error continues in the newly released OpenGL 4.2 beta driver. I pulled the error reports taken under Microsoft Windows Operating System Version 7 X86-64, as well as ran a GPUZ logging of my AMD card's sensors:
I don't know if these logs will help effect a solution for this game, but I'm not sure where else to start in poking AMD to fix these problems.
I've still been using 11.3 with City of Heroes since 11.4, 11.5 and 11.6 caused crashes after 15-20 minutes.
I'm not sure where we can start testing, but I do have list of unstable drivers with CoH.
Unstable 10.10 and 10.11 with 5770
Stable with 10.9 and 11.3 with 5770
Stable with 10.6 with 5750
Stable with 11.2 and 11.3 with 6870
Any progress on this? I am really getting frustrated with the random lockups in the middle of a task force - only to get booted from the team, and loosing hours of effort!
