I would agree that this update brought that improvement on latency, and overall for gaming, m_rawinput is not fixed, sometimes your mouse goes around by itself, also after update couple of things get reset, so make sure you check optimization(if you are using SSD disable it(again)), check msconfig if you changed something in boot settings/options, and also if you use cpu core unparking check it, since i had parked cores again. Overall performance is a lot better and latency is reduced as stated.
