Re: VBO not faster than immediate mode?



Yes.  Use the OpenGL profiler and you disable the back end of GL calls to see what would happen if your drawing was infinitely fast.  In your case you would between 5 and 15 percent gain.

To do:  make simulation faster.

Thanks to all for great suggestions.

First thing I tried was shark (my first time). 
It appears that my app is spending 84% in my simulation-function and about 5.4% with glBufferDataARB().
Should I read that as whatever I do with VBO's or DL's there's only less than  5% theoretical gain for overall speed to be achieved?

I wouldn't want to try to optimize drawing if there isn't more to gain.
