I used to play osu! normally about 4 months ago, but when I updated it to the Halloween version and the version after that, I got a serious FPS drop problem. I get only 10-15 FPS (it used to be 240) in the fullscreen mode. When I cancel the fullcreen mode, the problem is solved but input latency is hugely increased. If I go back to the stable(fall back) version, the problem is perfectly solved, but I wonder if there is any possibility to solve the problem in the latest version since the homescreen is much wonderful than the fall back version
