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
