WebJun 30, 2024 · A texture buffer is a specialized buffer resource that is accessed like a texture. Texture access (as compared with buffer access) can have better performance for arbitrarily indexed data. You can bind up to 128 texture buffers per pipeline stage. A buffer resource is designed to minimize the overhead of setting shader constants.
