V4080 is an OpenGL 4.3 driver and exposes 208 OpenGL extensions (GL=189 and WGL=19) for a HD 4600: Support for OpenGL extension: GL_EXT_polygon_offset_clamp.cl_intel_advanced_motion_estimation – provides access to Intel’s motion estimation hardware acceleration block that can be used by media processing applications including custom transcoders and image stabilization.cl_intel_subgroups – this extension enables work items to share data without use of shared local memory.This will provide improved video playback capabilities on the platforms. GPU accelerated decode of HEVC video file format including both 8-bit and 10-bit support.Improved video playback through partial hardware acceleration support for the VP9 video format.Intel has published a new version of its graphics drivers for Intel HD 4000 / HD 5000 / Iris that brings the following changes:
