I have no idea why this happened, but suddenly whenever i start Osu!, it immediately runs at around 2-3 fps, and the memory usage skyrockets from the normal 40-60MB-ish to 190-250MB! I have a great computer, 1.5GB RAM, 2.79GHZ processor, and 15GB HDD space free. I've always been able to run Osu! fine before, and I've restarted several times with no improvement. The music plays fine but the game and menus are at a near-standstill. I've also tried removing all songs from the folder and reinstalling Osu!. Anybody had this happen before and/or know how to fix it?
