I've tried much of the solutions above, only fix I've found is either dropping mouse polling rate to ~125hz or installing an older driver (I'm using 457.51)
I do want to update this to say that the newest driver (461.72, released today) still causes this issue. Just finished testing it out in a private match, without any additional people. In fact, I think it's actually gotten worse with the latest update. Gonna be reinstalling the old drivers again.

@Skha I've been using the one from Dec 2nd (457.51) with little issue (if you move the mouse a LOT for a while it'll start to hiccup, but that's about it)
Gonna be testing the one that came out on March 16th and will update it here.

Update: Still causes issues. Have decided to change the polling rate to 125, as that seems to completely resolve the stuttering without having to change the driver again
