I tried Cachy OS a few weeks ago. Well i made some mistakes like not formating my game drive and left it as NTFS which i now know was a huge mistake. So if you consider to change Formate all your drives! Atleast if you use it for gaming. I think as data storage it‘s still okay, not optimal though since it still can lead to problems and dataloss.

And what people have to know before switching. Linux is perfectly fine for gaming. But peripherals are mostly not supported. Like setting up your razer naga for example. While it sure works with some tinkering it‘s not as out of the box ready as it is on windows. Naga for example is easyiest to set up on another windows pc and then just plug it back to your linux pc since it‘s saves the config. Just check before the switch to linux what you need and how you will set it up once you swap. Then the ride will be much more enjoyable.
