It’s some low-end Intel i3 processor. It was super smooth, and considering that laptop basically a garbage (Nvidia GPU, which is not used in Linux, I use the integrated Intel one), it played quite well for me. It looks like the difference with Windows is not in its favour. It’s really easy to try it, especially if you have a spare hardware. Eg Dota 2 is free to play, so all you need is to install Steam and download the game. I use Fedora Silverblue, which I can recommend for an average user. (I use Arch on my primary laptop and PC.) Also, I’ve heard good things about Bazzitte, but I personally don’t like Linux distros based on other distros.
