So i've got my "EVGA GeForce GTX 570 HD 2560MB PhysX" working in a fresh 10.7.4 install on my old MP 1.1 In CUDA-Z it looks like CUDA is working... right? And in Luxmark it finally regognize the card having OpenCL working. But how much i want CUDA to work in Blender i only seem to get OpenCL working. I followed the step 2, 3 and final step on the tinymacx86 page the other steps didn't match my hardware. I also tried using Zeus to flash my 570 so i would get a boot screeen using Cindoris rom file but i failed, Zeus didn't manage to flash my card so still no boot screen, is doable to flash a standard 570 so it will get the boot screen? Anyone have a clue how to get Blender to regognize and use cuda on my 570? Thanks a bunch!
