Bazzite/eGPU/Dual Boot/Handheld/Final Fantasy VII Rebirth

FFVII Rebirth on Windows so many audio glitches is virtually not playable.

FFVII Rebirth on Steam Deck does not have any audio glitches but the performance is crap.

I have few Windows handhelds, so I am thinking to dual boot Bazzite to run it on Linux/SteamOS

But I would love to get eGPU (NVIDIA or AMD) going to push the graphical performance further.

Doable?
