I must admit that when I did not have the OSSC I was playing M.U.S.H.A a lot and I never found the lag to be a problem, actually I could not note lag at all. I only realized that it had an impact when I found that I was able to finish the game with the OSSC . In your TV the lag is probably at least 100ms, but I would say that if you feel that everything is fine and responsive, it is OK.
