@UP_LordPlumberYou'll know if the mouse thing happens. It just completely locks up and you can't look anywhere.
What I mean by stiff or clunky is when doing slides, or when like jumping into the slide and then jumping again at the end out of it. Also, when doing any sorta bunny hopping kind of stuff. It just feels like you're being slowed down more then before.
I've been experiencing that with vaulting as well. It definitely takes multiple attempts in certain spots.
@sk1lldOverall, I thought the mouse in game felt pretty okay, but it's hard to tell if things are not working properly in the moment. Usually you die instantly in this game, and it's hard to pinpoint that the mouse wasn't moving fast as it should have. Or with that weird recoil behavior that was discovered a couple of seasons ago.
I also get this weird thing when I ADS, it'll get stuck in ADS when I let go of the aim button. Like in the hip-fire stance, but I'm still zoomed in. I use the Default ADS option to get a little more zoom on all sights. There is some weird behavior with that though too.
I'm always yeeting myself past stuff. Very annoying.
