Cycles render appears not to render on GPU Lately I bought a Radeon GPU to speed up my rendering proces, but I didn't notice a significand decrease in rendering time. I checken my processes and my GPU only used about 2% of its capacity, while my Intel used about 75%. Which is strange because i turned off the use of my Intel in my preferences. I tried rendering a different scene; same results. I all the latest drivers and stuff; still no change.
I already set my tiling to 256 x 256, so that can't be it.
The equipment i use:

Blender 2.90
Radeon (TM) RX 480 Graphics
Intel(R) Core(TM) i5-6400 CPU @ 2.70GHz

So my question is, is blender using my GPU at all? And if so, is there any way i can make blender use more of my GPU?

You may want to check settings: Edit-&gt;Preferences-&gt;System-&gt;CyclesRenderDevice
Since I run on NVIDIA mine are different but you graphic card needs to be check marked in one of the tabs.

Furthermore, check out recent guides for speed improvement. Most important tip is the tiling. For GPUs it should be larger than for CPU.
