How do I change my GPU rendering OpenGL?
You can select single-GPU mode or one of several multi-GPU rendering modes. OpenGL Rendering GPU lets you select which GPU to use for OpenGL applications. If one GPU from an SLI or Mosaic group is selected, then all GPUs in that group are used. Select Auto select to let the driver decide which GPU to use.
How do I optimize my GPU?

Why is Blender not using the correct GPU?
Scroll down to the section labeled “Performance” ( possibly not the correct name ). Change both the tile size values to 128 or 256 ( Different values will be better based on scene and GPU. However 256 is usually a good choice for GPUs ). Restart the render and see if the GPU is utilized correctly.
Why is my GPU not rendering in cycles?
Just a quick note: Windows Task Manager doesn’t show CUDA utilization by default (which is what Cycles uses). To have that show up, click on the “3D” above the graph and choose “Cuda” or “Compute_0” in the drop down that pops up. It will then show correct utilization.
Why is the CUDA kernel not working in Blender?
Once the kernel is built successfully, you can launch Blender as you normally would and the CUDA kernel will still be used for rendering. This error may happen if you have a new Nvidia graphics card that is not yet supported by the Blender version and CUDA toolkit you have installed.
Can a GPU be used for both display and rendering?
If a GPU is used for both display and rendering, Windows has a limit on the time the GPU can do render computations. If you have a particularly heavy scene, Cycles can take up too much GPU time.
