I have tried to make blender faster by using my Nvidia GeForce GPU in the user preferences window and under the render options in the properties window.[![user preferences set on GPU](https://i.stack.imgur.com/85OLp.png)](https://i.stack.imgur.com/85OLp.png)[![render option is on GPU](https://i.stack.imgur.com/94qTB.png)](https://i.stack.imgur.com/94qTB.png)
But I can see in the task manager that the CPU is used mostly[![CPU and GPU usage](https://i.stack.imgur.com/WFNOL.png)](https://i.stack.imgur.com/WFNOL.png) and even though it is set on multiple tiles it is still using only one. How could I increase the GPU usage and the amount of tiles? Thank you for the answers:)
