my dad is trying to play some game on his PC but when started a box comes up with "video card does not support pixel shaders." can anyone tell me what they need to get as far as i was aware the onboard graphics would do the job?
Just for interest,Graphics cards have two types of shaders, pixel and vertex, in varying numbers of shaders. I think that most manufacturers use mostly pixel shaders with a few vertex shaders thrown in! the number of shaders a card has is called pipelines. Vertex shaders are the ones that draw the straight lines, ie indoors/corridors etc and the pixel shaders do the rest so you can see that you need more pixel shaders in games as there are more "other things" to draw than straight lines. nVidia has broken the mold by using a unified shader arcitecture, ie no pixel/vertex shaders, just 128 pipelines of unified shaders that can do either. this does away with having some shaders sitting doing nothing if the scene it is drawing is predominantly pixel/or vertex. I'm sure someone will correct me if i'm wrong!!!
