Path tracing VS Path tracing+CUDA

Post by DJ AntOn » Mon Jul 28, 2014 9:17 pm

I do not see any difference. :roll:
propose here to upload your short comparative tests of CPU vs CPU + GPU
p.s sorry for my english, it's google-translate :)
This first test: CPU vs CPU + gfx560ti CUDA6.0 20min
How much help % gpu acceleration ?

Try running the GPU in OpenCL instead of CUDA.

Activating the information overlay would help here to see ifs faster.

Anyway, GPU rendering is strong with exteriors, scenes with open areas.... not interiors.
Drop CUDA, since OpenCL was tweaked and fixed the most in the past iirc.

small difference is visible at a resolution 4000x2666
Zom-B thank you, I'll know
but I would like to better
