Intel has launched the latest driver update for their integrated graphics. This update brings full support for Windows 8. HD 3000 graphics are found on Ultrabooks with second generation (aka Sandy Bridge) processors while HD 4000 graphics are found on newer Ultrabooks that use Intel’s third generation (aka Ivy Bridge) processors. In addition to some game-specific performance updates, Intel has also enabled 4k Ultra HD video output and OpenGL 4.0 for Ivy Bridge / HD 4000, as well as OpenCL 1.1 for Sandy Bridge / HD 3000. All Ultrabook users should update, even if your Ultrabook has discrete graphics!
