Using Different shaders for different LOD for assets

HelionDark

Is it Generally better to have same shader for all LOD of objects or its more viable to use multiple shaders with different size of texture maps?

Depends.  Different shaders = more drawcalls.  Different shaders also breaks batching.  But if the lower LOD shaders are significantly faster then it could improve performance.  You would need to test and profile it.  I have used this technique on a racing game where I turned off nearly everything, even removing textures, for things in the far distance that were just silhouettes in fog. 

Different size texture maps is already done through mip-mapping.

Just read about mip-mapping, i think will stick with one good texture and use mip-maping. tnx
