Those driver tools are often bundled with malware and do a poor job validating what they download is safe and correct. They are often associated with services that crawls the internet for downloads and tries to match the hardware id.

Generally, drivers are available from the motherboard or device manufacturer page. That said it’s rarely the solution and for your gpu (amd or Nvidia) they already have their own tool for keeping you up to date.

But with Linux most of that is taken care of for you by either the kernel itself or your distro’s maintainer.

Most games work fine on Linux and may only require small tweaks. You can check the games you’re interested in playing on protondb. http://www.protondb.com/

The notable exceptions are games with aggressive anticheat software. Such as but not limited to (EA games, PubG, Fortnite, GTA5)

If you’re looking for something “easy” look into Kubuntu LTS.
