Thanks Michael!
From experimenting with PTS on my i7-3840QM (HD4000) laptop, I get nearly double the frame rate from the Unigene benchmarks, Sanctuary goes from ~7fps to average 13.33fps; by setting perf-bias to "0" and pstate governor to performance.
Intel Performance With Ubuntu Linux vs. Windows 8.1 Is A Mixed Bag

Earlier this week I published an extensive set of results from thirteen discrete AMD Radeon and NVIDIA GeForce graphics cards benchmarking various OpenGL games and comparing the Ubuntu Linux and Windows 8.1 performance when using the official AMD and NVIDIA drivers for each operating system. Those results were very interesting for both the AMD and NVIDIA GPUs, but now it's time to see how the Intel graphics are performing under Ubuntu and Windows 8.1 Pro x64. Making things even more interesting here is that Intel has only an open-source Linux driver and no closed-source solution.

I have to disagree with the interpretation of the Xonotic "Ultra" and "Ultimate" results. Sure, Windows gets higher peak and average fps, but look at the minimum fps numbers: In "Ultimate", the Windows result at 14fps is closer to the out-of-the-box result of 12fps than it is to the Mesa10 result of 17! Of course none are really playable numbers, but I'd prefer to play a game that drops down to 17fps than one that falls to 12fps no matter how smooth it is when you stare at the floor! ;-)

Originally posted by RushPL View PostMichael, would it make sense to do the same tests on Wine as well? I wonder if some of the Linux results could come closer to Windows, due to running actually the same code. After all, Linux binaries and Windows binaries might be compiled completely differently.

Originally posted by tarceri View PostHmm, I really wish Michael had waited a couple of weeks to do this comparison. There are a whole bunch of shader optimisations that have been posted to the mailing list this week. A number of i965 specific one's but also general glsl optimisations which should help all drivers. This one seem like it would have given much improved results on Unigine Tropics: http://lists.freedesktop.org/archive...er/047194.html
"for tropics, that accounts for most of the effect, the FPS improvement is 11.67% +/- 0.72%"

It would be good to see these tests redone with these patches applied.

Graphics driver guys should push DE guys more. In case of a performance regression it's usually the DE bunch who screwed up
