JoWooD and Phenomic would like to inform you that we are aware of the problems if you forcing the Anti Aliasing option through the control panel for your ATI videocard.
We are in contact with ATI to solve this problem to which they responded:
"ATI has already addressed the driver problems seen when forcing AA through the control panel. A solution will be provided in one of the next driver releases, most likely in December but possibly in the very early new year."
