Unity OpenGL perfomance regressed in 6.4

[František Zatloukal]

Unity OpenGL perfomance rgressed significantly in latest Quantal update.
These regressions were originally discovered and reported by Michael Larabel from phoronix.

If you look at discussion, users are getting angry from this. Everybody awaited perfomance improvements in Quantal. We will reach Beta soon and there are just regressions.

These regressions should be fixed before final Quantal Quetzal release. Unity OpenGL perfomance wasn´t good and it must be improved quickly(improved means improved, not regressed!).

Actually performance is much better than Unity 5.x in 12.04, but yes, the regressions shown there for the 6.4 and the effort to go through all that trouble to do such a benchmark and find the regression will get devs to notice it.

By the looks of the work done in 6.6 it looks as if they are already working on it.
