Nvidia OpenGL Performance

1 post in this topic

Hi to all!

I have a Geforce GTS 250 2gb installed and currently Snow Leopard boots with a patched dsdt file under Chameleon v.2.0 RC1.


If i boot with 64bit Kernel then i get with OpenMark around 5000fps.

If i boot with 32bit Kernel then i get 3300 fps.


I see that the gap in performance is huge enough..but i cant understand the reason for this, since Apple is claiming that 64bit kernel is only for systems with 32GB ram and doesnt offer any performance boost...


Can anyone confirm this with the utility i upload?

Thx a lot!
