I have an object that consists of many triangles. Then I compared the rendering processing time with VAO and VBO.
With VAO I got range about 0.05 second < processing time < 0.3 second
But the frame rate is about 2-3 per second
With VBO I got range about 0.0002 second < processing time < 0.03 second
but the frame rate is also about 2-3 per second.
What I'm wondering is why the frame rate does not increase as the processing time of rendering with VBO decreases?
