Will GTX 680 with 1500 CUDA cores work 3x faster than gtx 580 with 512 CUDA cores?
Namely - is speed of rendering a (linear) function of CUDA cores?

Hope to see some tests in Octane soon

Well rather than have Lux as a benchmark for OpenCL Refractive/Otoy should give reviewers Octane for Cuda testing.
Got to get out and promote themselves better as well now. The launch of Kepler tomorrow is a missed opportunity for waving their gpu rendering flag. Lux is fairly obscure to most people and yet these open source guys are doing it better. R/O will have to wait another 18 months for the next gpu series release. Probably someone else beats them to it.
