GTX 280 OpenGl small performance ?

[ccteam]

Hello guys,
I've assembled my Hackintosh with Gigabyte X58A-UD7 Rev 2.0, i7-980x, 12GB Ram, Graphics card Gigabyte GTX280.
I've employed MultiBeast 3.0.3 and everything works right except Open GL performances which are very low compared to Win 7.
With Cinebench 11.5 on Windows I've a score of 50.81 fps, on Snow Leopard 10.6.5 the score is 28.86 fps.
I've run Cinebench also with an ATI 4850, and the score was 34.75 fps. How come the GTX 280's score is so low than ATI 4850 moreover compared to Windows7?
My Hackintosh is overclocked to 4.26GHz. Can anybody help me to improve my OpenGL GTX 280 performance?

However with MultiBeast 3.0.3 I've used the following installation options:
-User DSDT
-System Utility
-Realtek ALC8XX
-IOAHCIBlockStorageInjector
-JMicron36xATA
-USB 3.0
-chameleon 2.0 RC5 Prerelease
-64 bit Apple Boot Screen
-Mac Pro 5.1
-Tonymacx86 Remixed

Network - RealtekRTL81xx.kext

Sorry for my bad english,
Best Regards from Italy.

I'm having a similar problem with my GTX 285 getting low OpenGL scores in Cinebench.

One thing you could try is using simbios MacPro 3,1. Apparently 10.6.4 and 10.6.5 decrease performance in some nvidia cards, and changing the simbios to MacPro 3,1 is one of the ways of fixing it. Read point 22 of this post:

That said, I'm using MacPro3,1 and my card isn't working as well as it could.
