hi, when my app is rendering, no matter what spec of pc, it seems to sit around 60fps, and uses 0% cpu no matter what.... but if i cover the window with another, it continues its routines but runs at 50% cpu and goes at around 2300fps.. i checked your nasha engine for reference and i see it also uses around 40-50% cpu....

so i tried running the render process on a seperate thread in a constant loop, but it stil used 0% cpu and sat at 60fps. again covering the window then moving the window out of the way, caused it to run at 2300fps for a v.short period, is there any hints or tips you could give me on this situation?

thanks in advance.
