So I recently downloaded Spiral Knights through steam after having not played it since around the time of launch. There were few issues at first, aside from some characteristic low framerate, though after a while the game began crashing at random intervals. The game will freeze for a few moments, the screen will go black and then back to normal, and then Windows displays a help bubble in the lower right saying "Display driver has stopped responding and has recovered successfully." At this time the game window has gone completely white and has to be closed manually and started up again. Initially it would only occur after over an hour but it has become far more frequent in recent days. It should also be noted I never had this issue before picking the game up again, so it's a recent occurrence and not something caused by my pc hardware.
I've tried a few things so far to fix the issue though none have helped. I've updated my display drivers (Radeon 4870 X2 is the card), I've updated java, I've attempted running it with 64-bit java and no steam overlay, and I've tried reinstalling the game. I did a little reading on the issue but nothing definitive was reported, generally just redirects to the tech support sticky. One post seemed to mention there being an issue with the AMD drivers which, if true, really leaves me in a bit of a bind. :<
Anyhow, if anyone could shed some light on the issue I'd be very appreciative. Thanks in advance.
Have you tried toggling Catalyst A.I. to Standard? That will disable any dual GPU settings that could cause hiccups.
