It's really a YMMV thing with Nvidia on Linux. I'm running 3 computers in the house on openSUSE Tumbleweed (mine and my 2 boy's computers). The computers all have various Nvidia cards and they all work just fine for gaming.
The "iffy" part for Nvidia is mainly focused on the troublesome issues some people run into with kernel updates and the drivers not keeping up. This is mostly a historical thing. It's been several years since I've ran into any Nvidia driver update related issues in Linux. The other major complaint about Nvidia is screen tearing... it's occasionally ugly. It's hard to resolve or fix,a nd in many cases it just is what it is.
The issue you're encountering with games running poorly on Linux Mint will probably not be resolved by distro hopping - I'm not trying to discourage some experimentation.. that's a fun/good thing :-) ... but the Mvidia drivers on Mint will be the same ones you will install on Fedora, and openSUSE and and and. The very first place I'd look is at the drivers. Are you 100% certain that the proprietary Nvidia drivers are actually installed vs the default Nouveau Nvidia drivers? You're running on a laptop... so that's the hybrid video card thing. Are you 100% certain that the games are launching on Nvidia vs running on the default Intel? If the games run terribly... they are very very likely not using the full capability of the 2060... either because the full drivers are not installed or you're running on the Intel by default even though the drivers were installed.
I explicitly go out of my way to avoid Air Canada and WestJet. They are both abysmal airlines. WestJet used to be good... but lately, it's become a competition between them and AirCanada to see who can fuck things up more spectacularly.
I'd say that Air Canada also lands last in customer service, quality of service, comfort, and adhering to the rules for customer rights... and pretty much EVERYTHING else.
