That sounds like a lot like something on your PC interfering with vorpX. Please follow the steps in the trouble shoot sticky post on top of this sub-forum.
Hottest candidates are: virus scanners, any sort of CPU/GPU utilities, game video recording/streaming software, chat programs and generally everything that can show notifictations in games.
Best way to trouble shoot this is to disable/uninstall every program running in the background that would not be there after a fresh, Microsoft only Windows install.
