Also getting this error message
Crossfire 2x HD6950 2GB. Happens frequently when video settings are set to Ultra, and about once or twice an hour when set to a mix of High and Ultra (no post-processing, some other options turned down). I've been experiencing it every single day since launch and barely anyone is talking about this error code. The last patch which claimed to address some stability issues did nothing for me, and it's beginning to feel like this is a hopeless situation. I've tried beta and stable drivers, I have the latest version of DirectX, and no other games have given me this problem before.
Additionally at launch whenever I had MSI Afterburner open, the game would crash within minutes. Really unacceptable conditions.
