I tested further, again with Baldur's Gate 3 as that's the only game I have
installed currently.

The game runs on the eGPU as confirmed by MangoHud, DXVK_HUD, and in-game
settings.

The GPU runs at 8GT/s also confirmed. Nvidia have some power settings which I
can't change where the GPU switches to a lower speed when it's not used
intensively, i.e. I'm on the desktop and only my wallpaper is drawn, as was the
case when I took the logs. When running a game, benchmark, YouTube video - it
runs at 8GT/s.

On thing I noticed while testing now is the power draw. For Unigine the GPU
drew ~280W and was running fine. For Baldur's Gate 3 it drew ~120W on the
menus, but only 70-80W when in-game, where it should be drawing at least 150W
and more. On Windows BG3 draws 120-160W on the menus and 160-200W when in-game.
Same settings used for both systems.
