Skybox rendering
Could anybody please tell me, why skybox rendering slows things down so much? It eats out approximately 15 fps while there are only 6 additional quads to render!!!
Well, the texture is being rendered across the whole of the screen.
Try reducing the color bit count or even try a compressed texture (if your card supports it).

Great thanks, DeltaVee. Fps are still > 50 even with the skybox rendering, so it was only the problem of understanding whether I''m doing something wrong
skyboxes use a lot of filrate either
A/ at the start of the frame dont clear screen + draw skybox (also applicable with depth)
B/ at the end of the frame, enable depth testing, draw the skybox
A is usaully faster on older cards, B is faster on newer.
of course it also depends on how much sky is showing in the final picture
