Due to recent increases in performance netted by better hardware, I've been playing with quality settings on my video adapter. I've found I can increase AA to 4x with very liveable frame rates, and even up to 8xs without losing too much more. I'm comfortable with the 4x though. The problem I have is when I try to engage AF. For some reason, when I try to start AH after engaging AF, the screen will flash back and forth between the desktop and the AH log in screen uncontrollably. I can ctrl+alt+del and wait for the processes menu to pop up, and then kill aceshigh.exe and I'm fine. It doesnt matter if AA is running or not. I can have AF set for "application controlled" and it's ok, but as soon as I turn it to "ON" and try a setting, I get the same problem.
