Oh thank you [insert diety]. I just got a new computer with a nvidia card and can finally start using cycles! Now I completely feel behind the curve, but am looking forward to working with cycles. I am glad that cycles worked out of the box for me. System pref turned on cuda and it worked. The computer I got is:
Asus i7, 8 gig ram, nvidia 660m w/2gig Not the greatest, but much better than the Imac with standard graphics. Cycles is now usable.
It’s amazing when you get some new fangdangled hardware that is just the bees knees. I’ve had me laptop for the last 3 years (i5) and expect it to go on for the next few years. I was doubly happy when I gots it brand new.
