Same. Here's video evidence of my point of view.

Surely I'm not the only one who finds this unbearable? Hope for a fix soon, loving this game so far.

Edit: In case it matters, I'm using Logitech.

Steelseries Rival 310 here if that makes any difference.

Same issue.. fps goes from 100+ to 5 with rapid mouse movement.. game breaking

Same issue, started right at the first boss after getting to the Stormfall town. Game suddenly starting having supremely unplayable levels of lag, was getting solid 90+fps prior.

I noticed that if I don't move my mouse that the FPS is steady- as SOON as I move my mouse at all the game totally freezes until I stop moving, then it catches back up. It's incredibly stuttery and jarring and really unpleasant. I will try to restarting but want to report it anyway as it'd surely be nice to not have to constantly restart and such. Restarting did fix it, and swapping to borderless windowed hasn't had it happen again, yet.

Exact same issue here. Started during the first boss fight after getting to town. Now I can't move at all without my FPS dropping below 30.

For my experience, I played through the game despite the problems (as infuriating as it was, lol) and I noticed the problems somewhat lessened, though are still present. Seems to be an Act 1 thing, but may have future impact in later stages.

This is happening to me as well, but I have a new piece of information. As far as I can tell, this ONLY occurs while playing online. My FPS is 100% fine when playing offline and 100% unplayable when I move my mouse in online mode. I'm using a Corsair gaming mouse, a version of the M65, I think.

I hope this helps Wolcen Studio trace this issue, as it breaks online mode completely for players who experience it.

As an update, I've confirmed that the issue is intermittent. Sometimes I boot up and it's fine; sometimes it's not. If I encounter it a restart will sometimes solve it.
