A pixel shader is a software program that is used when processing graphics and it computes color and other graphic attributes of a pixel. It is possible to identify the pixel shader version of the graphics card installed on a computer system. Pixel shaders play an important role in determining which video games can be played on the system. There are various versions of pixel shaders available from two leading manufacturers, nVidia and ATI. As the pixel shader version is directly proportional to the capabilities of the graphics card, it is important to know the pixel shader version on the installed graphics card.
Identify the Pixel Shader version of your graphics card
Games will be compatible depending on the version of Pixel Shader implemented in your graphics card.
Therefore it is important to determine the limits of your graphics system.
A Pixel Shader is a graphics function that calculates effects on a pixel level. Depending on the desired resolution, several million extra pixels may be necessary to achieve what is required. This takes a lot of computing power.
Here are the different versions of Pixel Shader with the Direct X version corresponding to the two leading manufacturers, ATI and nVidia, and also for the integrated chips from Intel (although their capacity for gaming is limited):
