Unity 6.6: Still Regressing On Performance?

[nadro]

The problem is the most visible for Intel cards, because these cards aren't too powerfull. AMD and/or NV owners shouldn't see too much differences (especially when use binary drivers). Of course I don't say that Unity doesn't require improvements in performance, but currently this is the mainly problem for Intel owners.

Phoronix: Unity 6.6: Still Regressing On Performance?

With the recent release of the Unity 6.6 desktop for Ubuntu 12.10 Beta 2, benchmarks were done to see how the OpenGL gaming performance compares to that of Unity 6.4 from the earlier beta state of the Quantal Quetzal, plus the respective Compiz versions. At least for Intel Ivy Bridge graphics under some workloads, it looks like the Unity/Compiz updates are slowing down the GL performance even further.
