Ill start with asking, how do I fix my resolution Issue? I know on the nivida site my card supports 2560x1600 Max. In the system preferences > Displays 1280x1024 Max. Tried graphicsmode = 2560x1600 no luck. I have a feeling an to edit a Kext somewhere must be made, inorder to add the reso?


Feel free to let me know what else I can do to optimize my Graphics!


My issue with OpenCL is that I believe its not enabled by default. Reading that from another guide on OpenCL Trouble shooting. Even after mutlibeast patch, when I run a OpenCL Tester my GPU isnt recognized as a OpenCL device.


Good info http://www.clbenchma...config=11982342


Update - Looking into nivida kext injectors for resolution issue. 12/4/2012
