New Legion Go owner with a few questions!

I have had an LCD Steam Deck and was looking for an upgrade.  Yesterday, I made my decision and bought a Legion Go. I chose it for the larger display and because Windows, for all its pros and cons, can be tweaked in many ways. There's a lot of information out there about the Go and how it can be tweaked. Not all of it is consistent! 

I want to run games from Steam and Xbox Cloud Gaming, as well as do emulation for other games. 

Just to get a baseline, I installed Stray on Steam and ran it with the display on max. The game looked great, but framerates were in the low 20s. I'm sure I can do better, but not bad for no tweaking. 

So...

1) Can someone point me to places where I can find reliable info on getting the most out of Windows and on how to make adjustments in Legion Space?

2) I've just heard of Bazzite OS, which is similar to SteamOS. If I tried that, I'd do a dual boot with Windows so that I could access BIOS updates. I understand that there's no real performance benefit, but are there any down sides to Bazzite? 

3) How does EmuDeck work in Windows? I understand it's still considered a beta on Windows. Any tweaks that you might recommend?

That's plenty for now. Thanks for your help!
