Some more info on the DX11 problems I've been seeing with my system. Sorry if these are already well known, I haven't seen anything on these exact symptoms (do these forums have a search? I can't see it...)
Symptoms: In DX11 rendering, an intermittent whole system freeze when loading a savegame or transitioning to a new area. The previous load has finished fine and all cores are being used. This problem goes away when I switch to DX9. It gets *worse* if (in DX11) I disable Aero or switch fro AA 2x to no AA. Very odd...
Also, often get a driver crash (BSOD) on exiting from DA2 to desktop via the main menu. This is cured by switching from DX11 to DX9.
I haven't yet tried DX11 on High.
