I am Rendering a scene Right now and the taskmanager says it only uses aprox. 6% of the GPU …
What? Is this right?
I set GPU everywhere
So a few things come to mind.
- Use OptiX, it’s way faster then CUDA for RTX cards and Cycles rendering.
- Double check stats using GPU-Z and check to see if there’s something else limiting the 4090.
- Are you using a recent release of the Nvidia driver, ideally the Studio set, unless you happen to play 0-day release games.
- Do you get the same result if not using the Experimental feature set?
- What resolution and sample settings are you using, is that during the actual GPU render stage or is the CPU still building/doing stuff?
- Have you downloaded the Blender Open Data test and if so, does it give results around what a normal 4090 does?
long time didn’t use windows, if i recall there was a more detailed view in which you see compute, rasterization video decode and stuff like that.
maybe you should look into that and the general view is averaging
cause 50C for a 4090 at 6% doesn’t make sense
edit:
was lazy to fire up windows here is a screenshot from the internet of what i mean
