Performance with CUDA or OpenCL

I'm currently using a MBP 15" Retina with 16 Gb RAM and the NVIDIA GeForce GT 650M with 1 GB VRAM.

Yes, I know this is not much for HD, but has served me well until now. Under R12 I keep getting "your video RAM is full" messages if it's switched to CUDA (should be perfect for this card, or not?). But when I switch to OpenCL, it works much better without any such messages with a decent amount of nodes, playing them in real-time.

Edited: Sorry, my CUDA driver wasn't up to date! After installing version 7.0.52 it works much better.

I let it stand for now, since others might see the same behavior.

Edited again: it still seems to better more stable with demanding footage if running under OpenCL.

The memory available to CUDA is extremely limited given a lot of Mac apps also use up GPU memory. Using OpenCL is much better on that laptop.

Thanks for the quick reply, Rohit, you are monitoring this list really well!

I'll keep posting more specific findings to the beta address too, for sure.
