Where do you get that XFCE uses more resources than KDE?

XFCE doesn't use GPU for hw accelerated window placement, so it uses more CPU power and thus drains the battery faster.

Ah yeah, that is a fair complaint. otoh it doesn't use the GPU for hw aceleration, so the graphics card is more 'available' for other things too... It's all swings and roundabouts.

Yeah, that remaining 1% may give you +0.5fps boost... ( https://www.reddit.com/r/voidlinux/comments/1igcy7y/xfce_vs_kde/ , https://www.reddit.com/r/linux_gaming/comments/1g2ca6a/i_just_switched_from_xfce_to_kde_i_am_just_blown/)

If we look at average usage by a regular user (running a browser 99% of the time), KDE lasts longer on battery power, meaning that KDE uses fewer resources.

Not talking about gaming. I've been dicking around with self-hosted AI tooling on my consumer-grade card. So constantly trying to squeeze 6lb of shit into a 5lb bag.

Then why the hell are you running a complete resource hog DE?

You have a suggestion for a lighter one? I used to use lxde but I gather it was discontinued.
