those who say it's smooth have low quality standards or never tried a game that was actually smooth to say shit like this.
those who say there is no performance problems have 60 hz monitors and for them 60+ is enough, some of them have vsync so they don't even see it anyways
for us that plays on 144hz monitors that's where you see how ugly this game is in terms of performance, it is undeniable, otherwise the person has just low quality standards as i said
for the performance, i'm talking about the poor fps in general, even my millionaire trader's beast computer can drop under 140 fps in some maps like cracked when sitting in a corner, it's so bad.
also most people play in 1080p while i play at 1440p (as a millionaire) which further consolidates my general analysis about those people.
