@toleda I figured that the FB personalities would match more easily with later generations past the 6xxx series. He [kayoone] maybe after the openCL advantages of his card rather than getting an nVidia card.
Hey Alex, it should be as simple as adding the SDK in first
Then proceeding to selecting your SDK of choice to build against
Lastly to make sure it's universal and you should be good to go because I've tested it on apps that were built for 32 bit already though I haven't tried with a kext I could try it out if it doesn't workout for you. Of course this depends on how you've coded it because things get depreciated with next generation LLVM compilers and future SDKs so previous coding can make or break a build but I'm certain you know that.
