Hardware Acceleration and Software RenderingFastgraph's DirectX libraries offer three types of 3D support: Direct3D hardware acceleration, Direct3D software rendering, and Fastgraph's own 3D software rendering. For video cards with partial or no 3D hardware support, Direct3D emulates the operation through software rendering. As you might expect, Direct3D hardware acceleration is very fast, but its software rendering is rather slow, often unbearably slow. Fastgraph's 3D software rendering is only slightly slower than Direct3D hardware acceleration (and sometimes even faster). This lets you write a DirectX application that will use Direct3D hardware acceleration if available, but if not, use Fastgraph's 3D software rendering without sacrificing too much in terms of 3D performance.
