8800 on 2006 Mac Pro = Poor Expose` performance?

[nightfly13]

Finally upgraded from my x1900XT to a 8800 partly because the mac client of Eve Online didn't like my having a mix of ATI and NVIDIA (7300) and that problem is now fixed, but I've noticed that expose` is a little jittery - maybe like 12 FPS if I had to guess, not fluid at all like I'm used to.

I have a pretty massive desktop - the 8800 pushes a 2560x1600 30" and a 720p Projector while the venerable 7300 pushes 2x(portrait) 1080p 22" monitors.

Is this just a reflection of poor Core Image performance on the 8800 and I need to suck it up, or is there something I can do to improve this? I'm basically posting because I thought in the recesses of recollection there was a firmware update or something to improve the 8800's Core Image performance... am I high?

the 8800 was always said to have average core performance...

Thanks for the post. I see that we have very similar setups. You're pushing a 23" ACD and a (presumably) 1080p TV from your 8800, yes? How would you describe your expose` performance?

Incidentally how do you type the e` with one key, instead of e + the key on the left of 1?

And finally, sitting here hammering on Expose` keys (show desktop, all windows, dashboard) back and forth now seems pretty smooth. Dunno if I just got used to it or, more likely, the sluggishness I observed previously was because of time machine backing up or something else... although I would think the GPU would do this lifting.. dunno... not unhappy with it right this instant

Now that I think about it, you might be pleasantly surprised in future OS X releases... As I find it rather smooth.
