I will address the elephant in the room here…
What kind of laptop is this? Make, Model ? Link?
Your laptop has an AMD and an NVidia GPU installed, which makes me think it’s probably an APU.
That being said, let me first point out that Rhino (or any application on Windows) does not “choose”, “pick”, or “determine” which GPU it uses…there is no way to do that even if it wanted to. The GPU used by any application is determined by which driver gets loaded into the application’s process space at the time it loads…The driver that gets loaded is determined by Windows…not NVidia’s Control Panel, or AMD’s control panel…Windows OS is who is in charge here…nothing else.
Now, there are configurations that can be made that can force Windows to pick a specific driver for a specific application…but as far as I can tell, everyone here has already exhausted those options and things still are not working.
You’ve indicated that you always run in “high performance” mode, so then that means you don’t even need or use the AMD for any kind of power or battery saving management. Therefore, since it’s not being used, I suggest disabling the AMD GPU from within the Device Manager in Windows.
@wim and/or @pascal can help walk you through that if you’re not familiar with the process. With the AMD GPU disabled, it means that Windows has no other choice but to load the NVidia drivers for ANY application it loads. I would give that a shot and see what happens.
If that doesn’t work, then I’m currently out of ideas…my guess is that none of your applications are using the NVidia GPU either ???
