If you don’t force your machine to use the Nvidia when using Rhino by following the instructions above, it will constantly try to use the intel because that is how hybrid machines typically work.
Just because you haven’t had problems in the past does not mean you won’t have problems in the future. If you are using the Nvidia denoiser and your machine is trying to use the intel, I’m not surprised you are seeing issues.
