一些图形修复，顶点缓存的性能改进和画面清晰的优化。
Some graphical fixes, a vertex cache performance improvement and a screen clear optimization.
唯一的要求是用于软件顶点处理的顶点缓存必须在系统内存中分配。
The only requirement is that vertex buffers used for software vertex processing must be allocated in system memory.
在这点之后，驱动可能会分配一个更大的缓存，或者你可能需要降低你的顶点数量。
The driver might allocate a larger buffer after this point, or you might need to reduce your vertex count.
