I have an issue that started just yesterday. I haven't done any system, software, or any changes whatsoever that I know of. In Rocket League, the game displays 60hz or less even though its running 200+fps on a 144hz monitor. If i ALT+TAB out and back in, it is normal for a few seconds. After a few seconds pass, it displays 30-60fps, even though my FPS counter displays 144. I have tried changing game settings and haven't found a fix. Any ideas?
