Ubuntu Now Often Leads Windows 7 On Intel SNB Graphics Performance
Starting with the cross-platform OpenArena test, the Linux performance really didn't change much on Ubuntu 13.10 with the newer kernel or Mesa. Intel developers have squeezed most of the performance then can out of Sandy while they're also more busy these days focusing upon Ivy Bridge / Haswell / Bay Trail improvements while also hardware enablement on Broadwell. With this OpenArena run, the Ubuntu Linux graphics performance is already faster than what's found with Intel's official driver on Microsoft Windows 7.
The open-source Intel HD Graphics 3000 performance really struggled on the HP Elitebook when running Unigine Sanctuary where it could only churn out an average of two frames per second compared to almost ten with the Windows 7 driver. Something is still going awry with the Intel open-source GPU driver.
