About Intel® Linux* Graphics

Linux* graphics is an ongoing field of interest at Intel’s Open Source
Technology Center (OTC). Community contributions range from driver
development and refinement to widespread project involvement, with a
particular focus on advancing standards for Open Source graphics.
Current OTC graphics work covers a broad range of efforts and projects,
such as: :

    Kernel driver is the core of the Intel Linux Graphics project, being 
responsible for all interactions with the hardware, driving different video 
outputs, mode setting, and converting bits into on-screen visible pixels.
    Mesa is the library responsible for 3D rendering, OpenGL compatibility, 
GLES and all the 3d-related components of Graphics on Linux and Unix systems
    XF86-Video-Intel, also known as DDX is the driver responsible for the 2D 
rendering within the X window system
    LibDRM is the middleware responsible for conversations between user 
applications and kernel driver itself
    Cairo Graphics is the 2D rendering and acceleration library
    VA API is the part of the stack responsible for hardware-accelerated video 
rendering, pre- and post-processing and output
    Wayland is the ongoing research project on next generation of window 
systems and composers

Title:
  [GM965] Poor performance ubuntu 12.04 on Intel® 965GM x86/MMX/SSE2
  [8086:2a00]

Status in Mesa:
  New
Status in “mesa” package in Ubuntu:
  Confirmed

Bug description:
  I have experienced some noticeable differences in performance of the
  graphics card (Intel® 965GM x86/MMX/SSE2) in Ubuntu to compared with
  Windows XP.

  In Smokin Guns Game, in lowest graphics, could not more than 60 FPS.

  In Windows XP, with maximum definition, played games requiring
  graphics capabilities, such as evalution Pro Soccer 2008 and 2009,
  FIFA Street, Counter Strike Source, Prince of Persia and GTA San
  Andreas, and the computer didn't lose performance.

  In Ubuntu, the simple game, Smokin Guns ( http://forum.smokin-
  guns.org/ ), play just 40/60 FPS in lower graphics... In higher
  quality, some 10/20 FPS.
