Well i got an Intel Chipset Family 82945G, I know that it supports Pixel Shader 2.0 and I've read that Toribash needs as minimum 2.0

Is this happening because my Graphics Card is Intel?
Maybe Intel shaders aren't compatible... but if somebody knows a solution, please help me...

Well a few intel cards dont support shaders, but that card should be able to supprot it.

But I think that version only has a good driver for Vista, so it wont support shaders in XP.

Anyways, you might wanna update your drivers to the latest.

Am on XP and my drivers are the latest and in Vista ir didn't work either :/...

Hmm then its probably your card.

I have a geforce 5500, that supports pixel shader 2.0, but the framerate is 0, so you cant actually play with shaders.

I guess pixel shader 2.0 wont run shaders well, you would need 3.0 at least.
