I too am unhappy with the default system graphics controller but after 12 months of nursing this PC have learnt to adapt...
Hints
Download the latest driver I suggest installing NVIDIA GeForce Experience it updates itself automatically..
In Windows 10 open the app: NVIDIA Control Panel >Manage 3D Settings > Global Settings > High-performance NVIDIA processor > Apply
(this may revert back to windows ''auto select'' when the tablet is detached...)
Avoid letting the screen sleep when the driver is being utilized it will crash the graphics controller when awoken.
In Windows 10 open the app: Settings > Power and Sleep > Plugged In > Never
(You can train yourself to press the power button when finished with your computer .. Its not that hard)
The easiest way to wake a crashed card driver is using Device manager > Search for new Devices
l have used the NVIDIA GeForce Experience from day one. Something I started with my SBw/PB
forcing the High-performance NVIDA processor causes bluescreens often and won't let me detach without changing back to auto-select
I always change those to never, and I set it to do nothing when I close the lid
I have to keep the Device Manager open at all times. unfortunately very few games can handle a disappearing dGPU. so I can't play most of the games i own, or games on the Game Pass.
