How were you seeing if the GPU was being used? Did you look at the windows task manager or did you get a notification in the task output to say that it GPU failed falling back to CPU? Most of the time your machine is processing images it is working on processes that don’t use the GPU, so sometimes you might miss seeing it use the GPU if you’re watching using the task manager. If you have a look at this thread you can see a great chart that shows the sections that do use GPU . On the RTX3060 if you try and use ultra settings it won’t process on the GPU.
