Most online gaming is currently borked on Linux because the anticheat software doesn't work. Does this get around that somehow? Will I be able to use the same method on my Linux machine?

EDIT: Otherwise 'runs the latest AAA games - and runs them really well' seems like oversell.

EDIT2: From their 'software' page: 'For Deck, we're vastly improving Proton's game compatibility and support for anti-cheat solutions by working directly with the vendors.' Yes!
