Great news. I always knew Linux had the potential for better gaming performance, because of its tweakability (you can tweak the OS so that very little background processes run, among other things)
Originally posted by BO$$ View PostAs a side question. Why are people still programming for directx? It works only on windows. Program for opengl and you make your engine more portable from the start for if (actually when) you'll port it to linux. It's not like directx is so much easier than opengl.... brainwashed devs..
Also, I believe Microsoft did something during the Vista days to reduce the performance of OpenGL deliberately.. I think that switched a lot of developers to Direct3D, but I'm not sure.Last edited by 9a3eedi; 02 August 2012, 12:28 AM.

This is what they said about the performance difference between direct x and open gl.
'This experience lead to the question: why does an OpenGL version of our game run faster than Direct3D on Windows 7? It appears that it’s not related to multitasking overhead. We have been doing some fairly close analysis and it comes down to a few additional microseconds overhead per batch in Direct3D which does not affect OpenGL on Windows. Now that we know the hardware is capable of more performance, we will go back and figure out how to mitigate this effect under Direct3D.'

While MS has most surely "has it out" for OpenGL, and DirectX is designed as a developer sink-hole (as with most MS solutions), it's also a very good API, arguably better than OpenGL in many ways. Especially HLSL vs GLSL.
DirectX is a OOP design, which helps with error handling and creates easier-to-understand frameworks. That being said, OpenGL is just fine itself, and any programmer worth his salt should be able to use it to make games and applications. The reason it's fallen behind in recent years, is because Windows has been The gaming platform for awhile.. that's changing now with the markets focus on Tablets & Smart Phones which are largely OpenGLES driven. So OpenGL is making a comeback, and I hope Valve puts a lot of weight behind this, and the Linux Desktop to bring great graphics to the open technology world.
I think some people here are too quick to dish out harsh words to DirectX, credit where credit is due. That being said, I'm a big supporter or Open Source and I'm hoping OpenGL not only sees market increase, but also API improvement in the years to come.
Thanks Valve!

Also, it's kind of shady of Phoronix talking about all this optimising of the Intel drivers, and how Linux gets 300+FPS, before finally sneaking in the note that the 300+FPS was Nvidia after many articles omitting this detail.
Finally, in reading the original blog post, it would have been interesting to see how many frames each of the three areas contributed to the improvement (6 FPS to 315 FPS).
I can assure you that same settings in ETQW in Linux or in Windows , no matter Linux Distro, ends up with ETQW looking much better than in Windows be it XP or 7.
In fact, video playback also look better out of the box in Linux than in Windows XP or 7 with VLC with same settings.
LINUX RULES and any resistance is futile !!!
