The availability of the Render Method 2D Textures, 3D Textures, and Paletted Textures is a function of your video graphics card and driver. Different cards and drivers have different features available. Some features are emulated in software and are much slower than features enabled by hardware. Newer graphics cards sometimes come with additional rendering features and improved performance.
