[Solved] GTX550 Ti - Luxmark

Goodday everybody.

I just made a clean Install of Mountain Lion now and i can confirm that the GTX 550 Ti works OOB. to get to the install i had to type: "PCIRootUID=0" in the Chimera Boot Loader Screen.

After some basic setup i disabled Dashboard as a Space and tested the Effect when adding a Widget and it worked.

Now i wanted to compare a Fresh Lion install with this Fresh Mountain Lion install and tried running Luxmark.
I used a patched GeforceGLDriver.kext from somewhere in Lion to get it work there in Lion.
But Since netkas posted that the Geforce Driver are better than the Lion ones i dont want to use the old from Lion in my Mountain Lion.

So can somebody provide a step by step Tutorial how to patch it?
I never done this Before because i used natit in my old Lion build (GT 430).
So Graphicscard is Fresh, Install is Fresh.

have a nice Day.

Solved by using this command

sudo perl -pi -e '$c++ if s|\x8b\x87\x1c\x0c\x00\x00\x89\x06\x8b\x87\x20\x0c\x00\x00\x89\x02|\x31\xc0\xff\xc0\xff\xc0\x89\x06\x31\xc0\x89\x02\x90\x90\x90\x90|; END { unless ($c) { warn "No substitutions made\n"; $? =1 } }' /System/Library/Extensions/GeForceGLDriver.bundle/Contents/MacOS/libclh.dylib
