Intel recently released an updated graphics driver for Ivy Bridge processors sporting either HD 4000 or HD 2500 GPUs. The new 126.96.36.19971 (or 188.8.131.52.3071 for those running a 64-bit OS) driver features several under-the-hood optimizations to reduce CPU overhead and improve the driver architecture itself.
The driver architecture improvements have also led to improved game performance. Intel claims up to 10% better performance in StarCraft II, Batman: Arkham City, and World of Warcraft: Mists of Pandaria (among others).
The chip giant also notes that the new driver supports OpenCL 1.2 for GPGPU calculations. The graphics driver update is only for Ivy Bridge hardware, and is compatible with Ivy Bridge hardware and both the 32-bit and 64-bit versions of Windows 7 and Windows 8. If you are running Intel's Driver Update Utility, you should get the new driver automatically.
Otherwise, you can grab the new driver from the following link, depending on your OS.
Unfortunately, these drivers are generic Intel HD graphics drivers. If your OEM computer is running Windows with an OEM-customized version of Intel's drivers, you are out of luck. You will need to wait for your OEM to update its driver package in order to take advantage of the performance improvements.

The new Ivy Bridge processors introduced a new member of Intel's graphics processor called the HD 2500, which has received less than positive reviews as the previous HD 3000 outperforms it. However those tests were for Windows applications and games, whereas the testing at Phoronix specifically pertains to the performance under Linux. They compare the i5-2400S, i5-2500K, i5-3470, and i7-3770K together in a series of benchmarks to not only test the performance but also their compatibility with Linux. It seems that perhaps the performance of the HD3000 and HD2500 are much closer in Linux than they were running under Windows, though both still lose out to the HD4000.
"Since the launch of Intel's Ivy Bridge processors earlier this year there have been many benchmarks of the Intel Core i7 3770K with its integrated HD 4000 graphics and then more recently have been Linux testing of the Intel Core i7 3517UE from the CompuLab Intense-PC and Intel Core i7-3615QM as found on the Apple Retina MacBook Pro. The newest Intel Ivy Bridge chip to play with at Phoronix is the Intel Core i5 3470, which bears an Intel HD 2500 graphics core. In this article are benchmarks of the Intel HD 2500 Ivy Bridge graphics with the open-source Intel Linux graphics driver stack."
