Updating pixel shaders

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. Here are the different versions of Pixel Shader with the Direct X version corresponding to the two leading manufacturers, ATI and n Vidia, and also for the integrated chips from Intel (although their capacity for gaming is limited): n Vidia Ge Force 3 series n Vidia Ge Force 4 Ti/ 4200 Go series ATI Radeon 8500-9250 series ATI Radeon 9500-9800, X300-X600 series Intel GMA 900/950/3000/3100 series n Vidia Ge Force FX 5000 series ATI Radeon X700-X850 series ATI Radeon X1300-X1950, n Vidia Ge Force 6 et 7, Intel GMA X3000 series ATI Radeon X2400-X2900, n Vidia Ge Force 8 et 9 and GT200, Intel GMA X3100, X3500, X4500 series ATI Radeon HD 3000-4000 series and Nvidia GT 300, GT 220, GT 240 series ATI HD 5000/,6000 n Vidia GT400 and GT500 series This document, titled "Identify the Pixel Shader version of your graphics card," is available under the Creative Commons license.It is very similar to the Nvidia Cg shading language, as it was developed alongside it.HLSL shaders can enable profound speed and detail increases as well as many special effects in both 2d and 3d computer graphics.

There are various versions of pixel shaders available from two leading manufacturers, n Vidia 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.

When a group of vertices (normally 3, to form a triangle) come through the vertex shader, their output position is interpolated to form pixels within its area; this process is known as rasterisation.

Using D3D10, I am drawing a 2d rectangle and want to fill it with a texture (bitmap) that should change a few times every second (like displaying video).
