Sparse Texture Extension (GL_ARB_sparse_texture)Įnables handling of huge textures that are much larger than the GPUs physical memory by allowing an application to select which regions of the texture are resident for ‘mega-texture’ algorithms and very large data-set visualizations. Ray tracing and global illumination algorithms are faster and simpler with unfettered access to a virtual world’s entire texture set. This bindless texture approach avoids the application overhead due to explicitly binding a small window of accessible textures. Shaders can now access an effectively unlimited number of texture and image resources directly by virtual addresses.

Streamlined Porting of Direct3D applicationsĪ number of core functions contribute to easier porting of applications and games written in Direct3D including GL_ARB_buffer_storage for buffer placement control, GL_ARB_vertex_type_10f_11f_11f_rev which creates a vertex data type that packs three components in a 32 bit value that provides a performance improvement for lower precision vertices and is a format used by Direct3D, and GL_ARB_texture_mirror_clamp_to_edge that provides a texture clamping mode also used by Direct3D.Extensions released alongside the OpenGL 4.4 specification include:īindless Texture Extension (GL_ARB_bindless_texture) The core rendering loop of many graphics applications frequently bind different sets of textures, samplers, images, vertex buffers, and uniform buffers and so this can significantly reduce CPU overhead and improve performance. New commands which enable an application to bind or unbind sets of objects with one API call instead of separate commands for each bind operation, amortizing the function call, name space lookup, and potential locking overhead.

Includes full control over variable layout inside uniform blocks and enables shaders to specify transform feedback variables and buffer layout.Įfficient Multiple Object Binding (GL_ARB_multi_bind) Shader Variable Layout (GL_ARB_enhanced_layouts)ĭetailed control over placement of shader interface variables, including the ability to pack vectors efficiently with scalar types. This provides significantly boosted performance for applications that intend to subsequently use the results of queries on the GPU, such as dynamic quality reduction strategies based on performance metrics. Significantly enhances memory flexibility and efficiency through explicit control over the position of buffers in the graphics and system memory, together with cache behavior control - including the ability of the CPU to map a buffer for direct use by a GPU.īuffer objects can be the direct target of a query to avoid the CPU waiting for the result and stalling the graphics pipeline. New functionality in the OpenGL 4.4 specification includes:īuffer Placement Control (GL_ARB_buffer_storage) This will help reduce differences between multiple vendors’ OpenGL drivers, resulting in enhanced portability for developers.
IS OPENGL 4.4 STILL USED DRIVERS
Khronos will offer certification of drivers from version 3.3, and full certification is mandatory for OpenGL 4.4 and onwards. In addition to the OpenGL 4.4 specification, the OpenGL ARB (Architecture Review Board) Working Group at Khronos has created the first set of formal OpenGL conformance tests since OpenGL 2.0.

OpenGL 4.4 unlocks capabilities of today’s leading-edge graphics hardware while maintaining full backwards compatibility, enabling applications to incrementally use new features while portably accessing state-of-the-art graphics processing units (GPUs) across diverse operating systems and platforms. July 22nd 2013 – SIGGRAPH - Anaheim, CA – The Khronos™ Group today announced the immediate release of the OpenGL® 4.4 specification,bringing the very latest graphics functionality to the most advanced and widely adopted cross-platform 2D and 3D graphics API (application programming interface).
