Is it too much to render 900 triangles in papervision ? I know the CPU model also affects, I'm using a core2duo 1.7GhZ. But rendering 900 triangles, as 5 cylinders seems too much, and drops the performance when rotating them for examples each frame... The FPS at normal is ~30FPS, but it drops when rotating or spinning the cylinders to 14~FPS. I'm really surprised about that performance, as Quake or Doom they were purely software rendering engines, and they had much more polygons than my application and they had a better performance of course.
That's roughly the limit that you're going to get with Papervision, as it's not taking advantage of hardware acceleration. If you're looking to take advantage of some of that hardware you're throwing at the problem, look into Away3D (http://away3d.com/).
