Fusion 360 is slow and laggy on a Surface Book (because of disconnected GPU)

Hi,
To begin with, I had a considerably slow Fusion 360 performance for the last year (It worked well before). I have a Surface Book (1 with performance base; i7-6600U, 16GB RAM, NVIDIA GeForce GTX 965M 2GB VRAM. This is maybe caused by bad optimization of Fusion 360 - forum guys said that I have a slow computer :)) I do not think so.

OK, my problem is: After the last update of the Fusion 360 and the graphics card driver update, the performance is disgusting. When I start Fusion 360, an error dialog is popped out about the graphics card is not powerful enough. After that, It lags even in an empty sketch in an empty design. I found that the Fusion graphics diagnostics dialog shows that the driver version and date is "unknown."

Screenshots documenting the above problems and facts are attached.

Please give me some information on what to do with this.

Have a nice day,
JV

P.S. there is some software info:

Fusion 360 version: 2.0.9009
Active Plan: Fusion 360, Student
System: Windows 10 (19041)

My first thought is that your nVidia card is not active.

My laptop switches to integrated graphics if not plugged in to save battery power.

I've got a power supply plugged in, but it led me to verify that the graphics card is active at all.

It helped disconnect and connect the keyboard with graphics card.

At least this information is for others and I recommend to clean the keyboard docking connector (I clean it regularly).
