    Poor Graphics Performance with GTX560-Ti


    Just got the new machine up and running, and most everything works under 10.7.4. The only issue I have is graphics performance. I've installed the Combo OpenCL Enabler for the Fermi 5xx via Multibeast and downloaded CUDA (Which shouldn't do anything for Graphics anyway).

    When I run Starcraft or Portal 2 I'm getting framerates in the low 40's and then they drop to the single digits as if I was using integrated graphics. Is there anything else I need to do in order to take full advantage of the card? Or a way I can check if something is amiss in the kexts?

    have you checked if your CPU is stuck at 1.6Ghz with the 10.7.4 update (where you had to add DropSSDT set to Yes in boot.plist)?

    also what is your mac type set to right now? try going to MacPro3,1 to see if that improves your graphics performance since it use power management for your graphics cards.

    It sounds like you need to edit your APGM kext.

    Add this entry to /S/L/E/AppleGraphicsPowerManagement.kext/Contents/Info.plist:
    Code:
    <key>Vendor10deDevice1200</key>
    				<dict>
    					<key>Heuristic</key>
    					<dict>
    						<key>ID</key>
    						<integer>0</integer>
    						<key>IdleInterval</key>
    						<integer>250</integer>
    						<key>SensorOption</key>
    						<integer>1</integer>
    						<key>SensorSampleRate</key>
    						<integer>4</integer>
    						<key>TargetCount</key>
    						<integer>5</integer>
    						<key>Threshold_High</key>
    						<array>
    							<integer>60</integer>
    							<integer>90</integer>
    							<integer>95</integer>
    							<integer>100</integer>
    						</array>
    						<key>Threshold_Low</key>
    						<array>
    							<integer>0</integer>
    							<integer>80</integer>
    							<integer>97</integer>
    							<integer>97</integer>
    						</array>
    					</dict>
    					<key>LogControl</key>
    					<integer>0</integer>
    					<key>control-id</key>
    					<integer>18</integer>
    				</dict>
    You should place it in the section matching your Mac identifier, e.g. MacPro4,1. I've attached my own AGPM kext for reference.
