If anyone here doesn't know what "Pixel Shader" is, I can show them exactly what it means.
However, it doesn't appear that the -use20 function does anything as Halo is centered around some very specific effects (the proper name for shaders)

Edit: Xbox has Model Shader 2, 360 has Model Shader 3 - Parallax Occlusion ftw!
... no it doesn't. The only DirectX10 cards in existance are the GeForce8.

Yes I know DXDIAG says you're using DirectX10. You're not, you're using 9L until there's DirectX10 hardware installed. DXDIAG just lists the largest DirectX version installed on your computer... not necessarily the version you're USING.
