Video While the official system requirements list:3D Accelerator card with 16 MB VRAM (*32-128 MB VRAM RECOMMENDED) 16 MB TNT2-class DirectX® version 6 compliant video acceptable, you would be pretty much insane to try running UT 2003 on a TNT2 card. We know, we tried. It's not pretty. This game expects a lot from your video system, and if you want to really enjoy it, you'd be well-advised to upgrade to even the lower tier of nVidia cards, or a Radeon. The demo, as released, did not work properly with Voodoo cards, but is expected to be fixed in the first patch. The game looks and plays beautifully on Radeon cards (you might want to Google up the Radeon Tweaker to further enhance performance).We found the game to be more graphics card sensitive than processor sensitive. Playing the game on computers ranging from low-end Celerons to cutting edge Athlon systems, everyone reported good results. No, this doesn't mean 125 FPS. Our gameplay ranged from about 30 to 100 FPS, but was fairly consistent, with one notable exception.Linux performance varied widely. It would appear that there is still a lot of work to do in this area. UT Linux pretty much flies off your screen, while UT 2003 Linux has some problems, including hard crashes, generally lower frame rates than in Windows, and major slowdowns in firefights. We were able to fix our crashes by setting NvAGP in XF86Config-4 to '1' from the installation default of '3', at no small sacrifice of performance. Even with an Athlon 1800 XP/Ti4600 combination, 1 gb of PC2700 DDR RAM, we were relegated to a mere 20-40 FPS in Linux.You also need to experiment around with what works best for your hardware. We saw better D3D performance on nVidia cards, and better OpenGL performance on a Radeon 8500. That's right, OpenGL! Even though Epic does not officially support OpenGL, the improvements they have made in this area are staggering. Go ahead. Try it. You might be pleasantly surprised at the performance, and how stunning it looks.
