Short description of error
I have started to get back into blender since I got a new computer. So I went to try out CUDA but it turns out that it is only using 0-10% of the GPU. I have tried changing the tile size and all that has done is slow it down. My renders going to 2-3 mins to 48 mins I have looked on the blender website and nothing has been useful. I have tried using 64x64, 192x192, 256x256, 512x125.
All getting slower...
