New iMac, Mac OS X Lion (10.7), AMD Radeon HD 6770M graphics card. Crashes constantly. Does a little better when I play offline, with resolution lowered and with basic RGB color profile. But still crashes in the same place after a few minutes (versus under a minute or at startup with standard settings).
Based on the error log (attached), it appears to be an issue with attempting a graphics boost during a render, but I'm just basing that on where the actual crash occurred, and of course there could be something else going wrong earlier and this may just be where it gets in trouble. But it always crashes in exactly this spot.
Please change the title if it looks like I've diagnosed this incorrectly, and any suggestions for settings to get around the problem until it's fixed would be greatly appreciated.
