- One thing is the parallel port, another thing is gfx.
-
- Imagine this.. I need a fast small polygons routine, and call the API.
- When the polygons are 2, it's ok, but when they're 20000, 99% of CPU time is
- wasted just only in the function call.
-
- Avoiding it and using inline code is already hardware banging.
