OpenGL* 2.1 Driver Installation Guide for Intel 965 Express Chipset Family

We recommend that you update to the latest Intel Graphics driver to get full API support. For more information about installing the latest graphics driver on your system, see How to Install an Intel Graphics Driver in Windows 10.

Intel 965 Opengl 2.1 Driver


Starting with Gen6 (Sandy Bridge and onwards), Intel GPUs provide performance counters used for exposing internal performance data to drivers. The drivers and hardware registers refer to this infrastructure as the Observation Architecture (internally "OA") [15], but Intel's documentation also more generally refers to this functionality as providing Observability Performance Counters [16] [17].

The H.264 decoding support is maintained in a separated g45-h264 branch, which can be used by installing libva-intel-driver-g45-h264AUR package. Note, however, that this support is experimental and its development has been abandoned. Using the VA-API with this driver on a GMA 4500 series GPU will offload the CPU but may not result in as smooth a playback as non-accelerated playback. Tests using mplayer showed that using vaapi to play back an H.264 encoded 1080p video halved the CPU load (compared to the XV overlay) but resulted in very choppy playback, while 720p worked reasonably well [22]. This is echoed by other experiences [23]. Setting the preallocated video ram size higher in BIOS results in much better hardware decoded playback. Even 1080p h264 works well if this is done[24]. Smooth playback (1080p/720p) works also with mpv-gitAUR in combination with ffmpeg-gitAUR and libva-intel-driver-g45-h264AUR. With MPV and the Firefox plugin "Send to MPV player"[25] it is possible to watch hardware accelerated YouTube videos.

In Mesa 20.0, a new OpenGL driver, Iris, is promoted to be the default for Gen8+. Certain applications run faster with it. You may disable it and revert to use the old i965 driver by setting the MESA_LOADER_DRIVER_OVERRIDE=i965 environment variable before starting any OpenGL application. This setting does not affect Vulkan applications.

The intel-driver uses Triple Buffering for vertical synchronization; this allows for full performance and avoids tearing. To turn vertical synchronization off (e.g. for benchmarking) use this .drirc in your home directory:

intel_idle.max_cstate=1 limits the processors sleep states, it prevents the processor from going into deep sleep states. That is absolutely not ideal and does result in higher power use and lower battery life. However, it does solve random hangs on many Intel systems. Use this if you have a Intel Baytrail or a Kaby Lake Refresh chip. Intel "Baytrail" chips are known to randomly hang without this kernel parameter due to a hardware flaw[27].More information about the max_cstate parameter can be found in the kernel documentation and about the cstates in general on a writeup on GitHub.

If you try adding intel_idle.max_cstate=1 i915.enable_dc=0 ahci.mobile_lpm_policy=1 in the hope of fixing frequent hangs and that solves the issue you should later remove one by one to see which of them actually helped you solve the issue. Running with cstates and display power management disabled is not advisable if the actual problem is related to SATA power management and ahci.mobile_lpm_policy=1 is the one that actually solves it.

For some 165Hz monitors, xrandr might not display the 165Hz option, and the fix in #Adding undetected resolutions does not solve this. In this case, see i915-driver-stuck-at-40hz-on-165hz-screen.

Users with newer 12th gen IGP's may see issues where plasma desktop is almost unusable. It appears to be an issue with accelerated items. Running glxgears will report a high frame rate, but the animation will not be updated.A possible solution here is to change the driver under X.

I want to start with my webGL project and minimal require is my graphic card support openGL 2.0.Problem exist because i have intel laptop with integrated intel 965 graphic media accelerator and driver is up to date and it support openGL 1.5.

Okay. just stay patient actually because ANGLE is coming. It seems to me that your hardware is able to run directX 9 and ANGLE is a project from google to allow webgl support from directX. But as the others say, you can't upgrade opengl drivers just like that. Or you could try MESA in the firefox build.

Sadly no. With a little more effort you can still develop against opengl 2.0 but you'll need to use another machine (or just buy a better graphics card) to test anything 2.0 specific (pixel shading for instance).

It's possible that updating drivers might help some, but probably won't make that jump. Otherwise, you could use something like Mesa3D, which does the rendering in software. It can be slow, but does support up through OpenGL 2.1 (including shaders), if memory serves.

angleproject is your best bet. Check out which exact 965 card you have from here (search for 'intel gma' in wikipedia), which also lists the OpenGL support version for these cards. It might take a couple of months though before you can use angleproject to accelerate your WebGL application.

I have a slightly newer 4500MHD, and I have the same problem. WebGL works on Firefox 3.7a4, but fails in the later versions a5 and a6. I had to use the latest drivers from Intel which claim to support OpenGL 2.0. The Microsoft drivers don't ship with OpenGL support.

I have an Inspiron 1525 with all the latest drivers updated per the Dell site (Driver Version but Intel site says there is a later verison ( - cannot install this, keeps referring me back to my OEM).

You will also discover that it's a typo on intel's webpage. The intel driver has revision number You'll notice that if you verify the driver revision after installation. Feel lucky: You'll also have DirectX 10.0 support.

In 2006, Intel completely redesigned their 3D hardware, introducing their first fully programmable GPU. It originally shipped as part of the chipset, rather than the CPU. It originally shipped with the 965G chipset. These are supported by the i965 Mesa driver, and the i915 kernel driver.

Crocus is great for the Intel 965 and above iGPUs, but the new Gallium i915G driver brings OpenGL 2.1 support to the 915GM platforms along with improved performance. (Crocus does not work with the "smaller number" GPUs)

According to mesa at , Mesa 10.0.1 implements the OpenGL 3.3 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 3.3. OpenGL 3.3 is only available if requested at context creation because compatibility contexts not supported.

Intel GPU support requires the linux-firmware-intel package. If you haveinstalled the linux or linux-lts packages, it will be installed as adependency. If you installed a version-specific kernel package (e.g.,linux5.4), it may be necessary to manually install linux-firmware-intel.

The kernels packaged by Void are configured withCONFIG_INTEL_IOMMU_DEFAULT_ON=y, which can lead to issues with their graphicsdrivers, as reported by the kerneldocumentation.To fix this, it is necessary to disable IOMMU for the integrated GPU. This canbe done by adding intel_iommu=igfx_off to your kernelcmdline. This problem is expected to happen on theBroadwell generation of internal GPUs. If you have another internal GPU and yourissues are fixed by this kernel option, you should file a bug reporting theproblem to kernel developers.

For newer Intel chipsets, the DDX drivers may interfere withcorrect operation. This is characterized by graphical acceleration not workingand general graphical instability. If this is the case, try removing allxf86-video-* packages.

If enabled while Trace is active, this variable specifies that the threaded contextshould be traced for drivers which implement it. By default, the driver thread is traced,which will include any reordering of the command stream from threaded context.

I don't see anything useful in the additional drivers section, except one Broadcom driver already activated. From Ubuntu Software Centre, I tried searching some other drivers and found Nvidia '173' and 'current' drivers. But I am not sure, if I should install them. Will it break whatever OpenGL programs are running fine?

OpenGL support is typically a hardware feature, and cannot just be upgraded by installing a new/different driver; the nvidia drivers you mention are for discrete Nvidia cards and will do nothing for your Intel graphics.

4) In the Graphics folder, find igdlh64.inf , (or kit49684.inf in driver, or kit 49659 in newer drivers) right click on it and choose to Open with Notepad. Scroll to the Driver Information section.

hello everyone plz help me with this problem of mine after reading the page and comments of course i saw that the issue for opengl (minecraft not opening in windows 10) was solved by downloading minecraft windows 10 beta edition but as i used to play minecraft on this laptop of mine before the upgrade i made (windows 10 from windows 7) I now want to play minecraft but downloading from appstore will cost me like $10 and minecraft is a free game. Any assistance will be highly appreciated.PS:i also read the procedure u said of the driver but i just cannot disable the Driver Signature Enforcement. Plz Help
