Well I can usually do a lot better than I'm doing now. If I had a fliptop and shit I'd see if I could transfer the GH3 chart for F.C.P.R.E.M.I.X. over and see if I could do better, but I can almost guarantee than I could. I get about 20% through the song on expert in GH3 and I'm sure I could get further. Have you ever played stepmania on someone else's computer that couldn't handle it and had laggy input? I have, and it felt the exact same.
