Random render speeds on the same scene

Hello,

I have this issue where the same scene with the same assets get rendered at totally different speeds in different days in which I open the scene. If everything is going well my GPU uses about 230 W and reaches a temp of about 60 celsius, it then renders a 4k scene in about a minute or two. Lets say the next day I open up d5 sync it with my cad program as usual and decide to run the absolute same scene with no changes to anything and the render time is 20-30 minutes, the GPU doesn’t go above 50 celsius and sits at around 90-130 W. It’s absolutely random from day to day and it really makes working for clients difficult. Is It possible that d5 somehow toggles between the external and internal GPU?

is it possible to get some kind of assistance?

Hi @erikshalatorski,

Sorry for your running into this.
How about the usage of your dedicated GPU memory when you are rendering? Is there much difference between the two cases? Is this an issue that has come up recently?
