Hello,
This might be an interesting tool for dri/driver developers..
from opengl.org: "New OpenGL tracer, analyzer and debugger: ApiTrace is a brand new project to trace, replay, analyze and debug graphics APIs. Using it you can inspect the OpenGL state frame by frame, call by call. You can analyze every shader, every texture, every buffer. You can also edit the trace itself and see the effects it would have on rendering in real-time."

"As a driver developer you no longer have to install all the games just to debug a problem, the report can simply include a short trace which you can use to immediately figure out what's wrong. As an application developer you can inspect every graphics call your app makes, you can analyze your api usage and you could automatically produce standalone testcases which you can send to driver developers."
See the blog post for more info.
