I thankfully haven't had any problems putting mayabatch on high (touch wood), but I don't know what the difference between high and real-time is so I never use it. I can agree that it might nor be for eveyone, but as I said before it worked alright for me.
The thing with this tip (as with all tips on the thread) is that it is a list of things I (and others) have found that help us work and if that's not the same for everyone then that's fine. You either take the tip and use it or try it, decide it's not right for you and move on.
I don't know what else to say to be honest.
