Crazy input lag from mouse?

My mouse is jumping around like crazy since the update, makes gameplay borderline impossible. see attached video.

Sorry, the video will not work, idk why, it will not input for about half a second and then jump to where i put it.

I’m also having the same problems. its driving me nuts, there’s been so many games where i’ve died due to the input delay

I also have this issue, but only in grb.
