Changes in performance
The absurd bloom filter used in Phoronix OpenArena test makes the test memory bandwidth bound (and ~halves its perf). Reason why OpenArena performance has dropped, is X intel driver defaulting back to DRI2 (DRI3 doesn't have the memory bandwidth overhead of DRI2, but it's still buggy).
Unigine Tropics improvement is an older improvement in Mesa shader compiler I think.
Unigine Valley drop could be this: https://bugs.freedesktop.org/show_bug.cgi?id=86242
Xonotic high quality improvement is an older improvement in Mesa shader compiler I think.
Plot3D has 0.6 million primitives and nothing else, recently there was a kernel change that improved BDW performance a lot in that kind of extreme micro-benchmark cases and a bit also in more realistic cases.
Triangle test low numbers are because DRI3 in Ubuntu 14.10 Vsyncs it. Newer X intel driver defaults back to DRI2 and there are some Mesa fixes also to the X DRI3 / present extension handling.
Volplosion is shader bound and the change is improvement in the Mesa shader compiler from fall, the test doesn't anymore cause register spills.
I hope Phoronix could do some testing with different X (=2D) drivers so that comments in articles wouldn't always assume issues with the 3D driver...
