While game engines handle the heavy lifting, they often add layers of abstraction. OpenGL offers "close to the metal" access. This allows developers to optimize rendering pipelines down to the instruction, squeezing every ounce of performance out of the hardware—a necessity for high-fidelity simulations and competitive gaming.
Instead of per-vertex function calls, OpenGL/WebGL uses : opengl by rexo web
