Re: Does the FX5200 has hardware fragment-shader support?
Doom 3 on a fx5200 can use the ARB2 path but it's 20-30% slower than using legacy NV20 path (which uses NVidia own fragment extensions for PS1.1)
Edit: I checked with a friend... the driver says that it supports GL_ARB_fragment_program/shader and GL_ARB_Shading_Language_100.
This should answer your questions
Pentium Dual E2180 (2GHz, 200MHz FSB)
Abit L95C (The one and only mATX with dual PCIe slots!) + 2x1 Geil Black Dragon PC6400
XFX 9600GSO 384MB
Little freak wonder
