I'm looking for some help, i record gameplays for youtube and on my old PC i had all my settings working, i only recorded League of legends videos back then because my PC couldnt run games at 60fps and record at a constant 30fps, now on my new pc (i7-4790-24gb-2gb GTX745) i recorded a game of counterstrike (60fps in game-constant 30 FPS in obs) i havent changed any settings but i tried to record a flash game, nothing crazy, had over 100 fps in the game and in obs it was at a constant 30fps, but once i opened the video in sony vegas the sound is really out of sync and the video is laggy as hell, i havent changed any settings, can anyone help me fix this problem?
