I finally decided on a gamedev laptop. Thanks for all your suggestions!

I went for the zephyurs g14, 2023 model. Nice and portable, lovely screen, keyboard is great, plenty of performance.

Utterly ruined by a buttload of asus bloatware. Battery life? Forget it. CPU power saving on battery? Nah. The thing was a space heater even when I was just web browsing.

That was until I found G-Helper, which gets rid of all the asus rubbish and has a lightweight widget that lets you do EVERYTHING.
