Updated Intel Graphics Stack On Ubuntu 14.04 Has Some Slowdowns
The GPUTest results were mixed in going from being unchanged to seeing improvements with Pixmark Piano and Plot3D to encountering slowdowns with Mesa 10.3-devel in other tests, similar to some of the issues with other Linux games noted.
Hopefully the apparent performance drops with Mesa 10.3-devel for Intel Haswell with some of the GpuTest runs, Xonotic, OpenArena, etc, will be addressed in short time for those habitual Mesa Git upgraders. We'll be back with more Intel Mesa performance benchmarks on Phoronix soon as it looks like the situation has changed.
