The test code I’ve written is not particularly optimized, but it’s doing nothing but drawing meshes so it has an unfair advantage anyway.

• 955,000 triangles
• Phong shading from one light source
• 4x antialiasing samples
• Covering most of a 1080P display
• 60FPS running on an XBox 360

Once I get to around 1 million polygons it starts to slow down, but I’m quite happy with this.  I know that adding texture and normal map will slow things down, as will adding multiple light sources. However, I don’t think it will slow it down so dramatically that I can’t handle at least 20,000 polygons in the final system. That should be plenty for my purposes.

There are still more tests to do for sure, but I’m feeling very optimistic.
