Well, I have just started with the tank challenge against Chirone, and ran in to a huge problem: When I have one image plane in the scene, the frame rate drops INSTANTLY to 2 FPS. Which makes it impossible to make anything. And the frame rate stays down even if the image plane is hidden. Is there a way to still have reference images, but not use image planes? Or a way to make the image planes less power-hungry? And my Mac isn't that bad hat it can't handle it: 1 gigabyte of memory and 733 MHz should be enough for image planes, right?
