**D5 Render Version: 2.5
**Graphics Card: Radeon 6800XT (CPU: 7800x3D, RAM: DDR5 32GB 6000Mhz)
**Driver Version: 23.9.1
**Issue Description:
D5 won’t use 100% of my GPU when rendering, but it goes to 100% right after the render is done and saved. (attached photo)
Also while using in PRECISE mode it wont use most of the GPU and wont display accuretely the image, and after a while it just slows down

Hello, it is normal that GPU are not 100% used, because we need to use algorithm to make it smoother and faster, with temperature and other elements into consideration.

Also, when rendering, you can use GPU-Z to monitor the GPU usage, I believe it should be used to their full potential. The Windows task manager may be not accurate.

Hello @raptorscream , I have the same problem as you, have you found a solution to the problem?

I also have somewhat similar issue. My GPU core is used at 40-45% but the VRam is used at max. Resulting in very time consuming renderings.

Did anyone resolve this? I’m running a video render and it is only using 13% of GPU and 30% VRAM. I have no other software open and I have a well cooled RTX4090 so I don’t understand why it’s going so slowly.
