I had this mindset for about 2 decades, from when I first played around in OpenSUSE and Compiz back in 2005 up to 2024 when I finally switched because of Windows 10 being put out to pasture by Microsoft. But since I'm now in my early 40s and no longer play competitive games as I used to 15 years ago, I've had zero problems with Linux and gaming.

So I totally understand your mindset as I too once thought the same.
Problem with waiting is of course that developers don't favor linux due to lack of people on linux playing game, so it's a vicious circle:

1. not playing on linux because it's not well supported by games
2. game devs not making games for linux because not enough players are there.

I hope you enjoy linux when you're ready.
