NVidia SLI Hybrid Fully Functional with Mac OS X 10.5.6

In its FAQ about GeForce products installed in the MacBook Pro, NVidia provide details about its SLI Hybrid technology applied in the Mac. Apparently the technology is not fully available in the MacBook Pro, but it will be fully supported with Mac OS X 10.5.6: Apple's hybrid graphics technology is supported under the Mac OS X operating system version 10.5.6 and higher only. Only the Hybrid Power function of the SLI Hybrid techbnology is currently available, the GeForce Boost ability allowing the simultaneous usage of both the video chipset and the discrete GPU will come later on with Mac OS X 10.5.6.
Apple might not like that a partner unveils some functions of the future version of its OS. However, it demonstrates also that NVidia is willing to update its drivers to bring its technologies to the Mac. One could now seriously think of a Mac Pro and NVidia SLI fully supported and managed by Snow Leopard.
In addition, NVidia mentions that when using BootCamp partition with the new MacBook Pro, one will not be able to choose which video chips to be used, it will be by default the discrete GeForce 9600M.
When applied in PC notebook SLI Hybrid technology does not provide the expected performance level so far, as both chipset and GPU spend a lot of time to exchange data and 2D/3D rendering are not really boosted. However, as a recent technology, it will improve over time and its GPGPU power might be important as well.
