Hello. I’ve been trying out rendering on a laptop I just bought. A simple test scene, Suzzane inside a box with an emission plane above. I set GPU (User Settings -> CUDA -> GeForce 840m) and set it to GPU Compute, but render times are pretty much identical. I’m guessing it’s working because it’s rendering one tile at a time, and increasing tile size increase render speed (but GPU at 256x256 is still as fast as CPU at 16x16), so what gives? Is there anything else I can do to increase GPU speed or is this one of those cases where GPU is on par with CPU? I can’t seem to find anything on the 'net.
