* Support for shaders with atomic counters and load-store-atomic read-modify-write operations to one level of a texture
* Drawing multiple instances of data captured from GPU vertex processing (including tessellation), to enable complex objects to be efficiently repositioned and replicated
* Support for modifying an arbitrary subset of a compressed texture, without having to re-download the whole texture to the GPU for significant performance improvements

Hardware support: Nvidia [[GeForce 400 series]] and newer, AMD [[Radeon HD 5000 series]] and newer (FP64 shaders implemented by emulation on some TeraScale GPUs), and [[Intel HD Graphics]] in Intel [[Haswell (microarchitecture)|Haswell]] processors and newer.<ref name=intel-support /> (Linux Mesa: Ivy Bridge and newer)
