Performance Optimizations

Every developer who creates real-time applications that use three-dimensional (3-D) graphics is concerned about performance optimization. This section provides you with guidelines about getting the best performance from your scene. 

• Keep the textures small. 
• Only set needed textures in material
• D3D Effect (Shader Text) heavy debase performance, especially work with multi-texture. Only use shader when really needed (if possible, instead of it by checking object's styles like Alpha Test, Alpha Blend, Color Add...); if a material include shader text, assign it to objects as less as possible.
