I was only able to install the latest CachyOS image by modifying the boot arguments in grub of the live installer, after reading the lengthy log file it pooped out after the first install fail.
I have no idea why people recommend this to people who aren't actually deep into tech and linux already.
Yeah, that's why I added the qualifier at the end. But I legit flashed a USB with the ISO, booted, installed the OS, installed steam, installed a game, ran it, and had 0 issues or customisations required.
I wonder if other Linux distros had the same issue.
Agreed. Recommendations to use Arch-based distros especially. My personal recommendation, which has ended up sticking for a few Linux-curious gamer friends, has always been Bazzite.
