Back in the early days of Ubuntu, I was blown away by the amount of interesting free stuff on Synaptic, so I started installing everything that caught my eye. A few hours later and my Ubuntu install was completely borked. I think the install scripts back then we’re pretty unregulated, so there was probably a ton of conflicting dependencies causing trouble.
I eventually reinstalled the os. Then I did the same thing again. Twice. Then I learned.
Aside from performance, I also noticed that older PC games work better on Linux than Windows nowadays. I really enjoy playing games from the late 90’s to early 2000’s, and they tend to run great on Linux with proton. Just the last year I’ve played all of Baldurs Gate 1, Icewind Dale 1 and Icewind Dale 2 on my scrappy Lenovo laptop and it’s been great.
I use an ESP32-C3 with Risc-v as my daily driver (for reading air quality sensor data off of a custom circuit) but I don’t think that’s what OP is getting at.
Your setup is close to my 2015 very-much-non-gaming laptop, so… I’d recommend retro gaming and/or modern 2D games. A few suggestions would be: Baldur’s Gate 1-2, Icewind Dale 1, Xenonauts, Battle Brothers, Wildermyth, Shadowrun Returns (and sequels), Into the Breach, Fallout 1-2. If you’re into programming games, that hardware should run everything by Zachtronics as well as Human Resource Machine and 7 Billion Humans.
