I'm using a warped cube to model a planet in DarkGDK and the framerate is extremely low because the planes that are facing away from the camera are not being rendered? Apparently not drawing away facing polys takes as much cpu time as drawing them so how can I fix this without subdividing the mesh a bunch of times and hiding individual components seperately.

I always thought that not rendering the away facing polygons increased performance significantly, and the framerate is at 170 when its more like 330 if all the hidden polys are removed so it obviously doesn't.

Not being rendered is not the same as not being there at all. Sure, it will increase framerate if backface culling is enabled, but not enough so it equals what it would be if they arn't there at all. Tis a problem you will have to live with :s

Yeah but I expected something. The framerate is exactly the same independant of whether or not the object is being rendered. How can you exclude polygons without hiding objects?
