This document is nice:

http://www.opengl.org/resources/code/samples/s2001/perfogl.pdf

It mentions something interesting:

"Depth testing is expensive..."

I am not sure if this includes verteces going out of view or so... in 2d
mode...

Maybe depth testing is not required to make verteces go out of view by the z
value as I was planning to do...

Actually this is probably not an issue at all anymore... since each verteces
will be determined after each round or so ?! ;)

But not completely sure.

So interesting read anyway.

Bye,
Skybuck.

This sux:

"
Once again, for certain architectures, this may be the best format for
specifying geometry. The only way
to know is to conduct a benchmark case
"

Would be nice if opengl/drivers had some hints for the programmer for a
change ! ;)

Bye,
Skybuck :)
