I just format my hd and reinstall everything. When I try to play SOF2, the game told me it cannot load the OpenGL subsystem. My video card is ATI Radeon 9700 Pro and I download the latest driver from ATI website. I also tried to update SOF2 and remove/reinstall SOF2, but not work.

This is the complete message:

many people have had this problem. the only solutions ever suggested was update drivers, reinstall game or maybe you just need to enable openGL on your card.
you say you "tried to update sof2".. but the console is reading 1.0 .. how did you update it? get the 1.03 gold patch from sof2files.com
I also notice the CPU detected is unknown.. Im not quite sure about that one. I just know mine say "amd 64".

but if you google this issue, you will find that most people, if not all have solved this with simple driver updates. Try again

find wiser2 and run it.

you need open GL drivers! a common problem in al Q3 engine games!
