Looking at the list of apps running, EVGA Precision overlay might be the culprit that is conflicting. Typically, overlay utilities conflict because they use similar injection methods to achieve the overlay as what Nthusim is doing for pre-warping. The two biggest culprits on overlay conflict are typically Steam and Origin's in-game chat modes. They need to be disabled from the client preferences. If that isn't it, it might be some new issue with Geforce Experience or Shadowplay. Both are doing some non-standard wierdness behind the scenes. Or maybe Raptr has an overlay chat element? I'd systematically go through the app list and isolate out things to track down which is the culprit.
