nfsking2 Posted December 13, 2010 Share Posted December 13, 2010 I recently updated the Graphic Card Driver to QUADRO MAC OS X DRIVER RELEASE 256, and it solved the V-Sync issue. But I found that my GTX480 get extremely low performance after installed this driver. Though the old 19.5.8f03.001 driver has the V-Sync problem, but the performance seemed great. Here is my benchmark screen shot In CineBench 11, the OpenGL framerate is only 8fps, while the GTX280M can get 31fps. Does anyone know the reason or the solution?

Try the command below as root user in Terminal then reboot using the I believe F8 key to get the Chameleon boot prompt where you would type in then hit enter key -f to force the reloading/caching of all .kext on the system. mv /System/Library/Extensions/AppleGraphicsPowerManagement.kext /System/Library/Extensions/AppleGraphicsPowerManagement.kext-10.6.5 Quote Link to comment https://www.insanelymac.com/forum/topic/239763-extremely-low-performance-on-gtx480-with-quadro-256-driver/#findComment-1601368 Share on other sites More sharing options...

malfunct Posted November 22, 2011 Share Posted November 22, 2011 Just for the record, the same thing happened to me, as if only 1 or 2 SMP's are functional right now. I'm trying this fix ASAP!!!
