    Phoronix: Intel Haswell To Boost Graphics Performance 2~3x

    Ahead of the official Haswell launch in early June, Intel released more details yesterday concerning the expected graphics performance out of the Ivy Bridge successor...

    I don't know about Rage/Doom 3 BFG at this point...I haven't had time to look into it yet (sorry). L4D2 is perfectly playable on my Ivybridge (Lenovo X230) with Mesa master at 1920x1080. I haven't tried 9.1 lately, but we have done a bunch of optimizations since then, and I'm seeing a lot more than 20 fps. You might also try turning Shaders and Effects down to Low, if you haven't already.


    We are all hoping for tessellation. Also we prefer good Wine support (Wine driver, not Linux driver). For example, a good thing is to do "winetricks glsl=disabled" and this will work as with an Nvidia GPU. Also if you can contribute something to Wine, will be good. For example, if glsl(enabled/disabled) can work fused, some shaders to GLSL some CPU-heavy not, it will be great. If you can contribute to an D3D state-tracker or to an LLVM based HLSL shader-compiler will be great.

    I'm just pointing out that Intel PR department do not know that Intel already provide OpenGL 4.0... on older hardware... And actually You are first Intel employee who answered such question IIRC.

    When will Rage/Doom 3 BFG run with mesa? How much faster would be mesa git compared to 9.1 for Ivy Bridge and Left 4 Dead 2? Team Fortress 2/Half-Life 2 DM was basically playable but L4D2 is too slow (around 20 fps @ 1920x1200).

    Now I don't know how much work GLSL 1.50 is, but is it more than half a year's work?

    OpenGL 3.3 is definitely going to be finished this year, at least for the Intel driver.
