For many people the RC runs better than the regular viewer. Not for me. RC gives me very bad stutters and crashes. And the same goes for the beta client, which is almost the same as the RC except Mono.
I just don't understand why there is such a big difference between the regular client (running very smoothly on my pc) and the RC and beta (running a lot worse). What exactly did they change which could cause this behaviour?
