real-time multiplayer games like shooters and MOBAs were just impossible to play competitively I understand that everyone has different tolerances, but I can’t stand even slightest lags (ms range), irregularities and visual bugs in games. Had to fight my way through hardware settings on a real PC at last update, now it’s smooth and immersive. I don’t play multiplayer games at all, but have a hard time understanding why someone would think “ah, I’m playing single player anyway, so enormous input lags are okay”. How do you play parrying (witcher, souls), shooting 2+ targets quickly (hitman, ghost recon), tight racing with such delays?
