"When there was one model on the screen it blazed. When there was two models on the screen it was very fast. When I got to 4 models it moved so slow I had to switch to fast tracking and caroon shading. When I got six models on screen it crawled, even when I switched to box tracking." OpenGL problem perhaps? I did switch to Sreed Software preview and: When there was one model on the screen it blazed. When there was two models on the screen it was very fast. When I got to 4 models it was very fast. When I got six models it's still very fast. Now I've got 10 models, 2 horses, a lot of props, microcosm landscape and a huge tent and it's still fast in smooth shaded. It's a bit slower in Texture shaded, but definitley not crawling. By the way, I only have 1Gb of RAM and a 2Ghz cpu. As for rendering with firefly, that is a problem, but CL has stated that there's a bug in it.
