What is the shader model in the video card?

Shader model (commonly referred to as SM in 3D graphics) is "Optimizing the rendering Engine mode". Shader (rendering or coloring) is a program that can operate on 3D objects and be executed by the GPU. With these programs, programmers are able to get the most desired 3D graphics effects. In a 3D scene, it typically contains multiple shader. Some of these shader are responsible for processing the surface of 3D objects, and some are responsible for processing the textures of 3D objects.

The role of Shader model:

Shader (rendering or coloring) is a program that can operate on 3D objects and be executed by the GPU. With these programs, programmers are able to get the most desired 3D graphics effects. Great convenience for programmers to write code and more high-speed implementation of various effects.

Version of Shader model:

When Microsoft releases DirectX 10.1, Shader model already has five versions: Shader Model 1.0 (DirectX8.0), Shader Model 2.0 (directx9.0b), Shader model 3.0 (directx9.0c), Shader Model 4.0 (DIRECTX10), Shader Model 4.1 (DirectX10.1) and Shader Model 5.0 (DIRECTX11) are still being updated in the future.

The development of Shader model:

SM 1.0 to SM 2.0: In the true sense of the technological revolution, SM2.0 gives the ability to display chips, people in the game also enjoy unprecedented visual experience, such as water surface lighting and atomization and other effects of the appearance of the game scene more real.

SM 2.0 to SM 3.0:SM 3.0 in addition to supporting 32bit floating-point operation is a bright spot, other special effects with SM 2.0 can also be completed. is equal to the optimized version of SM 2.0.

SM 3.0 to SM 4.0: Maximum number of instructions increased from 512 to 64,000, temporary registers increased from 32 to 4,096, and 128 texture allowed to operate at the same time; the material texture format becomes the RGBE format supported by the hardware. Eliminate the need to specifically decoding processing HDR rendering process, greatly improve HDR efficiency. 8192X8192 's highest texture resolution is 4 times times higher than the original maximum 2048x2048 resolution.
