The usual drill? Update drivers, DirectX? Check Event Log for application log errors? Did you do it?
well dxdiag shows I'm running directX 11 and there are no problems reported on display, sound or input tabs. All other games programs work fine. debug.err is a long file and I wouldn't know what to look for unless it leaped out at me with something like "ERROR" ...." which is doesn't. There are a number of "file not found" type warnings, that's all. My card driver is not the latest version, which is 12.10 and has just been released, because it causes display flickering in Skyrim and I'll wait for a fix. I reverted back to 12.8.
All other programs seem to work fine. If someone could tell me what to look for in debug.err I'll turn on anti-aliasing again and check, but this looks on the face of it like a FE specific issue which should be known.
