Reading about OpenGL performance, there is a threshhold when memory thrashing (swapping) starts, I think they mean between GPU on-board memory and computer RAM.
Also there is a limit on reasonable amount of vertices, poligons and quality complexity. Lorenz has 4000 spheres, each is 10x10=100 verices, that is half a million verticies with normales and lighting -- isn't that natural to expect a performance impact? --- "Miller, Raul D" <[EMAIL PROTECTED]> wrote: > Brian Schott wrote: > > [various mac specific issues] > > One of these days, I'm going to borrow a mac and install > J on it.
