Frozen vertex buffers are a type of optimization technique used to improve the performance of 3D graphics. They are created by combining multiple small vertex buffers into a single larger buffer. This reduces the number of draw calls and the amount of data that needs to be sent to the GPU, resulting in faster rendering times. Additionally, the GPU can cache the data in the frozen vertex buffer, further reducing the time needed to draw the scene. This technique is especially useful for complex scenes with many objects, as the reduction in draw calls can significantly improve performance.
