Upgrade to Windows 11 stops using my Nvidia 1080

Hi All,

as the title says , I have upgraded from windows 10 to windows 11. FYI I am on l the latest version of windows , nvidia drivers and DR.

After this upgrade the graphics card is no longer being used to render out my fusion projects. I have turned off the auto selection steps of the prefderences and specifically selected the Nvidia card (and rebooted) but still DR uses the CPU. Using the resource monitor I have confirmed this.

Does anyone else have the same experience? Found any way to fix?

Regards,

Billy

NB please do not be the person who asks for every tech spec trying to be the dogs b. I dont see the point unless some has specifcally had an issue with a version.

Fusion mainly uses the CPU, but it depends on which tools you use.

To verify that the GPU is used successfully, try rendering a video clip with noise reduction without using Fusion.

I never knew that fusion used the cpu more than the gpu. I did see the gpu performance increase doing what you said. I must have another issue -maybe the windows 11 amd bug as i have Ryzen 3950 - i applied these driver last night and havent tested it yet.

Basically my fusion particle system is unusable now. I cant even wait for the auto rendering to complete as it takes minutes to do a few frames…might even consider rolling back to windows 10.

Fortunately i only do this as a hobby and not used for business somplease be careful if tempted to upgrade. If i find a solution i will advise

Fusion is not color space aware. So using Davinci color space managed and Fusion will not work (yet). You can work in Fusion, but it will not render. Maybe this is the issue

Fusion uses GPU's 3D engine harder for 3D scenes and particles, compute operations are generally light unless using Resolve's effect nodes

Thanks guys. Just logged on and tested the particle project I was working on successfully on Win 10 - im getting 61.8 secs/frame!

Ive just copied the same nodes into Fusion 17 and the playback changes - a lot better to 1.9 secs/frame with the CPU doing most of the work again. As its a particle node tree sohuldnt that be usign the GPU based on what you have said guys?

(didnt know how to attach the second jpg)

thanks

Rendering 3D particles in default OpenGL renderer occupies the GPU the most, not calculating them, that's mostly CPU...compared to that, Fusion's native nodes that use GPU OpenCL for compute tax the GPU very lightly (do not confuse OpenCL with OpenGL, that's not the same thing ) It's just a little aid to the CPU.
