Intel OpenGL Performance: OS X vs. Windows vs. Linux
Phoronix: Intel OpenGL Performance: OS X vs. Windows vs. Linux
As mentioned last week when publishing the OS X 10.8 vs. Ubuntu Linux benchmarks, a large Intel OpenGL driver performance comparison was being carried out at Phoronix. The comparison is now compete and here are the results when comparing the Intel HD OpenGL graphics performance under Apple OS X 10.8, Microsoft Windows 7 Pro, and Ubuntu Linux 12.04/12.10. The results of this Intel OpenGL gaming performance comparison are quite interesting, but reveal some troubling Linux facts.
OSS-driver Team son of a lesser god even in intel?
So far for the many praises on Intel about their friendliness on open source.
They have the tech and SW know-how to make their HW go 50% faster and openGL 4.0 compliant, but they use it only on Windows...
Maybe I'm a little bit harsh, and Ok, great job to the OTC, but just like for AMD: couldn't the OSS-driver team be helped internally more?
IP to defend? on AMD side maybe, but come on, on HD3000....
Anyway, it slowly and constantly progresses. At least there's a hope , unlike the perspectives on future we had 5 years ago.
And the collaboration with Valve should pay
wow linux driver is faster than i thought.
Ok, intel can run some engines which are 10y old but it would be much better when it could run idtech 5 (even when done via wine). But thats not the case. Tests would be more interesting with hd 4000 however, then you could at least compare heaven.
With all the money Apple has I thought their drivers will completely obliterate everything. It appears that their drivers are not perfect at all (compared to Win7), and often are slower than Linux.
I remember reading about 'Link-Time Optimising' when compiling the Linux kernel. I know it's not fully ready yet but might that in the future increase performance when it comes to OpenGL?
Playing devils advocate: Why the automatic assumption its the driver that's at fault? I mean, theres a LOT of drivers out there with reduced functionality compared to their Windows counterparts. Maybe the issue is less with the driver writers and more with the host OS?

As another thought, I remember from previous tests that Linux usually performed worse than Mac and Windows at higher resolutions but sometimes came out on the top on lower resolutions. Linux also seems to perform worse on widescreen than 4:3. On the other hand, Mac tended to have the opposite results. I know its very time consuming and probably tedious for Michael to test so many screen resolutions but the results have proven to be apparent.
Because the Linux stack is based on the in-kernel DRM and Mesa, and others aren't?
