I am doing a rather intense scene in the blender cycles engine. This scene contains many hair strands.
However, When I switch to the GPU rendering system, there is always an error containing a message such as, ran out of CUDA core memory, or CUDA failed to launch. I have no idea why this is happening, I have a fairly decent PC, and I feel like i should be able to handle the scene.
I have and nvidia GeForce GTX 690 with an Intel-Core i7-4790K CPU.
I have no idea why this is happening and would appreciate a quick reply.
