Windows 7 - hat is pixel shader and can we increase pixel shader virtually

hi guys i just want to know what is pixel shader and can we increase pixel shader virtually

Pixel shading is what makes computer graphics seem so real. It works on a pixel by pixel basis, determining the lighting, shading, and color of each pixel - bringing infinite possibilities.

If I'm correct, anti-aliasing, anisotropic filtering, etc will affect pixel shading. For ATI, this can be done through Catalyst. NVidia settings should do the same.

Not sure what you mean by virtually...
