I have a ATI Radeon 9800pro but display options available are only 800x600(max). Is there any way to raise the resolution to 1024x768? I know it is not my computer with the limitations as I can play Half Life 2 etc on 1244x68 at max details. Help appreciated. A forum search shows this topic has been discussed but no solution to the problem of adjusting to resolutions not included in the in game display options offered.
