Never had this happen before: now when I play, I intermittently can't move very quickly. You know how if you just quickly tap one of your WASD keys your character kind of twitches in that direction? Imagine tapping quicker than humanly possible, but you're actually holding down the key, trying to run that direction, but only moving each tap very little, you're barely stuttering in the given direction now, bup-bup-bup-bup-bup.
I can't jump because of this, can't fly either. Sometimes it clears up a few second,s only to come back. I'm usually spending more time NOT moving than moving normally.
Tried zoning, tried restarting computer. No setting graphically or of any other sort have been changed or updated. My keyboard seems to do just fine typing, as I am doing now.
ETA: To be clear, it's not the world that's doing this stuttering, it's not rubber-banding. It's me that's stuttering. Seems I can use my attacks just fine though.
