Finally, in stress testing, the GPU fails to switch to 3D mode and remains at 2d clocks.
Stress testing and fullscreen : true, i neevr thought of that. That is a clear limitation though, that will never be removed. I have to keep the window small enoguh so that the CPU will not be overwhelmed by pixels to check. A Picture in 1680x1050 has 1 764 000 pixels, one in 512x512 has 262 144 pixels...

For the 3d mode switch, this is driver controlled, not application controlled. The only thing i can say is that ATI's drivers are poorly made on that regard, and that they won't switch to 3d mode if you're rendering something in a window. And it's quite good for them, as some of their recent graphic cards have cooling that are really unefficient, and OCCT GPU makes them hot, hot, hot...

ATI even reduced Furmark's speed (and iu'm currently more efficient than furmark) to 20fps so that the GPU won't overheat. They did that in the drivers. Rename furmark's executable to something like "3dmark06" and things will get hot again.

I'll get on the 3d mode switch as soon as i can, in window mode, to see if i can get things running. I wish i had an ATI to test that, though :/
