Thanks for feedback. Sounds about right, and you could reduce screensize in options menu if needed more speed (assuming that helps).

Yea its running pixel doubling which is vulnerable to visual glitches... you could disable pixel doubling but then youd have to squint to see 400x240 instead of zoomed.

Very rarely i will see similar flashing (using pixel doubling on 800)when picking up item or taking damage... you see that every time? I looked and couldnt find option (like config variable) to disable flash, maybe someone else knows of one. Also do you have same issue when no other programs/windows/icons are running in background?
