I don't remember if it was ATI or Nvidia but there was a pdf in the early/mid 2000's that I think was called or had a section dedicated to where's your bottleneck. It introduced a bunch of terms and definitions (fillrate and the like). I was wondering if anyone has this document or a link to it.

Thanks in advance.

How about this guy? http://http.developer.nvidia.com/GPUGems/gpugems_ch28.html

Or maybe https://developer.nvidia.com/sites/default/files/akamai/gamedev/docs/EG_04_OptimizingGPUPipeline.pdf

Thanks for trying but no those weren't it, I've seen those before. The one I'm talking about IIRC has the same type of Flowchart but even more complete. I might have to dig up an old hard drive (if I still have it) and use an external enclosure to access it... I really liked that document, very complete from what I remember.
