The directx exampile program Sprite Animate in the Microsoft DirectX 8.1 SDK gets 15fps on my old pc that has: 1MB graphic card,40MB of DRAM, 200MHZ CPU, and has directx 8.0 on it.
Now the vary frist C&C that uses directx looks like its getting about 30fps. So how would i set up my programs to get more fames per sec on old pcs?
