            fpsTimer = System.currentTimeMillis(); // Update timer to current time.
            fps = frames; // Set fps to frames

        }
        deltaTime = (System.nanoTime() - lastDeltaTime) / 1_000_000_000.0D; // Set delta time from last delta time
        lastDeltaTime = System.nanoTime(); // Set last deltaTime to current delta Time
