i just got a new computer, and am trying to run a game that is telling me that my graphics card has to support pixel shader v1.1 or above. i think im running an asus motherboard, and the graphics adaptor is an SiS 661FX. the driver is v6.14.10.3611. how do i fix this? i can't find/ don't know if there is a newer driver, and can this gfx card run pixel shader at all? what is pixel shader???
