Rendering issues after latest last week's update

Ever since the update last week when the new maps were released, I have been encountering weird stuttering that makes the game basically unplayable (looks similar to having constant 200 ping). I’ve played since Beta and never ran into this issue. I’m running a i-5 6600k, Evga 980 with custom fan profiles, 8 GB Ram, and a 60 Hz 1440p monitor. I’ve tried turning the graphics setting down but to no avail and I’m really confused as what changed in the last update. Any help would be appreciated.
