I'm trying to render with gpu in cycles render but, even tho looking at the settings it seems like everything should be fine , actually looking at cpu and gpu usage i noticed that the one actually being used for rendering was still the cpu.
my cpu model is Intel(R) Core(TM) i5-3550 CPU @ 3.30GHz
my gpu model is GeForce GTX 1080
my CUDA version is 8.0.61
can someone help me figure out why is this happening? thank you :)
