As part of their regular improvements to drivers, Intel has released a new HD Graphics driver that applies to all Ivy Bridge and Haswell Ultrabooks. The new driver fixes a number of bugs and enhances game and program compatibility.
Intel regularly releases new drivers to increase performance, security, and compatibility. The latest driver update for Intel HD Graphics (220.127.116.11.3257) was released just last week. While there’s no major changes to performance in this patch, Intel has made a number of game-specific bug fixes and it’s recommended that everyone with compatible hardware apply the update.
The update applies to all Ivy Bridge and Haswell Ultrabooks which could have any of the following: Intel HD Graphics 4000, 4200, 4400, 4600, 5000, Iris 5100, and Iris Pro 5200. This update does not apply to first generation (Sandy Bridge) Ultrabooks with HD 3000 graphics.
We recommend using Intel’s automatic updater to get the driver (in case there is a new one by the time you are reading this). Some Ultrabooks come with OEM-modified drivers which are not always properly detected by the Intel automatic updater. If that’s the case, you can download the current latest driver here (be sure to check for a newer version if you’re reading this more than a month after the published date). Be aware that OEM-modified drivers may have specific tuning for power/heat purposes, and those modifications will be lost if you use Intel’s generic driver.
