Hi Adidia, Hi Sergey, Got some news : With GPU activated ( via nvidia-primes ), everything work, including CPU and GPU backend. But if I deactivate my Nvidia GPU, I've got a segmentation fault, even if backend if only CPU.
For information, my perf stat on my "old" laptop ( with dragon fly .blend ) NVIDIA GeForce GT 420M / Intel i5-460M(2,53GHz) Mobile CPU * Without osd : ~ 0.1 fps * CPU : ~ 1.6 pfs (x16) * OpenMP : ~ 1.6 fps (x16) * OpenCL : ~7.3 fps (x73) * CUDA : ~ 7.2 fps (x72) * GLSL : ~8.5 fps (x85) Regards, Julien On Thu, May 22, 2014 at 1:08 AM, Aditia A.
