Modifying an arbitrary subset of a compressed texture, without having to re-download the whole texture to the GPU for significant performance improvements

These capabilities can be combined, for example, to maintain a counter at each pixel in a buffer object for single-rendering-pass order-independent transparency Ĭapturing GPU-tessellated geometry and drawing multiple instances of the result of a transform feedback to enable complex objects to be efficiently repositioned and replicated Notable new features in OpenGL 4.2 include:Įnabling shaders with atomic counters and load/store/atomic read-modify-write operations to a single level of a texture. As with 4.1 this is primarily for use with DX11 class hardware (GeForce 400/500, Radeon HD 5000/6000), however NVIDIA's developer site mentions that some features can be made available as extensions to work with hardware as old as OpenGL2/DX9 class hardware.
#Opengl 4.1 download update
Khronos routinely updates the OpenGL specification to add new features to the API for existing hardware and this update is no different, coming a little over a year after the release of the OpenGL 4.1 specification.
