When rendering my CPU usage is at 100% and my GPU usage is at 1%. The rendering is taking so long. I have the GTX 1080 so I should be able to render my object very fast.
The first thing to make sure of is that Fusion 360 is actually using your dedicated GPU. Often if you have an "onboard" graphics chip and you also have a dedicated video card, Fusion may pick up the wrong one to use. This was my case until I used the Nvidia Setup routine to tell Fusion 360 to use my Quadro 2000M, a rather old card but better than the onboard graphics. So go here and make sure for yourself.

The Rendering/Raytracing in Fusion 360 does not utilize the GPU at all. It is completely executed on the CPU.
Same problem here.
CPU: i5 12400
GPU: RX 6650 XT 8Gig
In rending 100% CPU.............. 1% GPU
