I’m running Quake 2 on pop os linux using steam, which is based on Ubuntu just like Mint. My desktop is a i7 3770 from that era. I think you will be fine on the CPU and RAM front.
The GPU I’m less certain about. It’s an old mobile GPU that was low end when it was new. But this is essentially a 25 year old game we are talking about. My advice is to just give it a try. It’s $10, and Steam will refund purchases no questions asked as long as you play for less than 2 hours.
It has somehow been fine for everything I’ve thrown at it until now. But after a decade, “it’s time to go”
A new rig with an i5 13600K and 7900XT is on the way. I’m trying to remember what game finally forced my hand at a big time upgrade last time around.
