I have an Abit KT7 motherboard with a 900mhz T-Bird CPU and an ASSUS V6800 32ddr video card.When I run Unreal in 1024x768x32 mode I get lousy performance. When I run it at 1024x768x16 it is just OK. With the Pentium 3 660E setup I had it ran fine in all settings. How can I improve performance? Is AMD that bad?
