I'm really hoping Mac gaming will get better in the next few years. The graphic horsepower is already available, now the limits are for games to be released for Mac and ideally compiled for ARM and implement the Metal graphics API. Unfortunately for now Fortnite is not releasing any new version due to their feud with Apple and CS:GO is still running through Rosetta 2. DotA 2/LoL is already running great AFAIK.
