graphic debugger

Just in case, you do not know this tool yet…

Here you can download GL debugger similar to gDEBugger, but working even with GL3 (should work with everything up to GL4.1, but I have not tried it). It works fine for me in linux and should run in windows too. Very useful tool IMHO. Thanks to author.

That looks really interesting, thanks for sharing.

About time. OpenGL badly needs these kinds of tools if it is to survive as a serious API and competitor to DX.
