I had a break from PA for few months and earlier I didn't have this problem... When I run a game my distplay starts blinking like crazy. Happens always in fullscreen no matter of graphic settings. Stops only when I change to windowed but I don't like it this way. I have updated my graphic drivers and have quite new pc... I dont know what to do now. Any clues? PS. Sorry for my english. It's not my first language
