Well obviously, how do you expect x264 to do anything at such absurd restrictions? 183k VBV bufsize?! Are you insane?
Its not fair to have a test where you use totally different VBV restrictions for each of the encoders--you're not passing any at all to Dirac, nor are you verifying that Dirac's stream abides by the same restrictions you've passed to x264.
Surprise surprise, when you massively cripple x264 but don't cripple Dirac at all, Dirac looks better! Last I heard a Ford Focus can out-race a Ferrari if you lock the latter to first gear, too.
