Cheating is rampant in PC gaming.
As bad as they can be, the randos talking through my console headset are far less toxic than the ones in the PC multiplayer community.
My computer’s performance gives me an unfair advantage so it’s not as fun; the playing field is more balanced when everyone has similar hardware.
All three of those are dealbreakers by themselves, so basically, from my experience, multiplayer gaming is unplayable on the computer. It actively makes me want to do anything except play computer games.
