Nvidia Quadro FX 580 recognized in Lion, but sluggish performance?

2 posts in this topic

Recommended Posts

I'm running OSX Lion on an EX58-UD5. With SL I added my Quadro FX 580 with EFI strings and it worked beautifully, QE was detected and graphics performance was the best I've ever had.

 

Now with the Lion install, GraphicsEnabler=Yes detects my card, but performance is sluggish.

Launchpad is the worst with what looks like 5fps when sliding between screens and opening folders/groups.

 

Playing 1080p movie trailers is choppy when other items are on screen, but when switching to full screen it plays smooth as silk.

 

Anyone else experiencing this? Any ideas?

Seemed to solved my own issue. I disabled AppleGraphicsPowerManagement.kext. This thing is a dream now! Super weird though... before disabling the kext I could actually hear my hard drive reading/writing when moving things around the screen... it was almost as if it was caching graphics/display to the hard drive?
