You basically need a Graphic Card supporting at least Shaders 2.0 to run Shaders. Obviously, a better graphic card is good too, since I'm experiencing problems with my Ati Radeon 9600, supporting Shaders 2.0. I can't run Shaders in Toribash 3.8, even after having updated my graphic card's driver.
Sup,
