WARNING: Battery saving mode is on

[[Unknown]]

Can you try the same git builds to confirm? The warning message is probably unrelated if an old version is showing better performance.

It's kinda like this: suppose one day they put up a sign saying "warning: children crossing" on a street near you. Afterward, you began hearing about traffic accidents several kilometers away. It's definitely because they put the sign up, right? If only they'd remove that terrible sign, all traffic accidents would stop happening.

I mean, sure, it's possible. Maybe people are being distracted by that sign, and then some time later getting into an accident. Or maybe, the sign was put up because of one problem and there are still other problems.

Lots of changes and updates were added in v1.2 and v1.3 and you didn't even say which games this was affecting.
