Hello. I'm new and need some help.

gfx cards dont hold any bearing on the speed of games, as long as your card supports opengl 2.x and pixel shader 2.x (which it does) then youre fine

make sure dual core is enabled in the config, and other audio in the hle settings is disabled

if thats already done theres nothing u can do but upgrade your cpu (ie get an intel core2duo 3.0 ghz or an i7)
