Quartz Optimization?

With the new build of us seem to be getting much better performance at higher redraw rates (<100). But even with these higher redraw rates the Quartz performance (such as the "genie" effect when minimizing and restoring a window) in OS X is still very slow (as in 1 or 2 fps). Is there any way that anyone has figured out at this point to speed up Quartz rendering?

i'd take a wild guess that for those quartz effects look really nice, they'd need to implement some sort of OpenGL support. i mean, as in using the real video card in the emulated machine. but i guess it'd be VERY hard.

i also believe that once they get their cpu emulation optimized (MMU stuff is the most speed-relevant optimization needed), it should start to get smoother.

but for a true OS X experience i guess they'd need OpenGL.

Opengl is an open standard, wouldn't it just be a matter of mapping the instructions to windows opengl routines?
just a thought...

I think the important word in your post is "just". I think it would be a little more than "just"....

You sure are pessimistic, Robo. What makes you think it would be so hard?

is there anyway to disable them?

Not being pessimistic, just realistic. Remember that there are only two guys doing the development, and like most development, 90% of it is just tedious work. I was more thinking of the enormity of the task rather than thinking it was impossible.

For Windows, OpenGL just gives a programmer an interface to work with, but if you wanted to interface Windows with the OpenGL from another operating system, there is a lot of work ahead...

Definitely not being pessimistic though, I think the developers of PearPC are probably capable of doing anything with it given time.
