GeForce FX and DirectX 9 Half-Life 2 Performance

It turns out that the console command we used “mat_dxlevel 90” doesn’t work properly with GeForce FX cards. Instead, Valve recommended we use the switch “-dxlevel 90” at the command line to force GeForce FX cards to run the DirectX 9 path. Armed with this knowledge, we set out to re-run our benchmarks and take new screenshots with GeForce FX running the video stress test in DirectX 9. Valve was also kind enough to provide a listing of the differences between the various APIs.
