Hi,

From what I know, the VBO usage parameter we set when we call to glBufferData (http://www.opengl.org/sdk/docs/man/x...BufferData.xml) has no effects.
From my experiments (with some years old CG both ATI and nVidia), there's no difference in timings whether I use STATIC_DRAW, DYNAMIC_DRAW or STREAM_DRAW, and whether I keep the same data in the VBO or I change the data of the VBO every frame.

Is this (still) true ?
