This allows developers to "introspect" or query the properties of a shader program at runtime more efficiently than in previous versions. 4. Advanced Texture and Geometry Features
The GPU can now generate its own draw commands based on its own internal calculations. This drastically reduces the overhead of the CPU-GPU communication bottleneck. opengl 4.3
OpenGL 4.3’s advantage was — compute and graphics shaders share the same buffers and textures without expensive copies. This allows developers to "introspect" or query the
