I use both Fedora (daily driver) and Windows 11 Pro (gaming), and Windows doesn't use much more RAM honestly. Fedora uses currently 10.5 GB of RAM with Firefox, Spotify, Plex, and Telegram running (looks like a couple of YouTube tabs in Firefox are having a party here with 1 GB of used RAM for three tabs...), and Windows is typically only 1-2 GB above this with the same type of usage. I have never maxed out my 32 GB of RAM on either OSs.

Judging by your avatar, you dry humped your waifu just half an hour ago, and now you're insulting an entire country. Your parents must be so proud of you. Did you not get a Nintendo Switch for Christmas, or what? Is that why you're being such an ass?
