I forget what the cure is for this problem. Is it the FR the game is capped to or the driver version I am using? I run AH in 1024x768x32. I am deliberately running slightly older drivers so that I keep some display functions which were left out on newer versions.
System:
P3 733MHz 190MB SDRAM
Win 98SE
GeForce 2 MX400 AGP 64MB Vid card with older Nvidia drivers (21.83?)
