so far I haven't seen this timing option have any effect whatsoever (even in timing-sensitive games) besides slowing down the emulator a lot. I think the result it calculates gets max'ed away the vast majority of the time. And the thing it enables probably isn't very accurate anyway. So let's see if we can get away with leaving it disabled for the time being...
