Large Latency/Lag?

Just started playing again after 2-3 months. Having a severe issue with latency and character movement lagging way behind. I will move forward, but keep walking 5+ seconds after I stop pressing the keys. Often times my key movements won't register till 5+ seconds later as well.

My sending and receiving are almost always below 100, and I have had no issues like this prior to today when I returned. It is also not affecting gameplay on any other games I own. Could it have something to do with a recent patch and incompatibility with certain drivers or graphics cards?
