After watching the video I am not surprised one bit PCPER was mentioned at all. I can remember a few years,when The TechReport started doing frametime testing using stuff like FRAPS. However,one day PCPER "devised" a hardware based system with a "collaborator" and IIRC,some of the AMD cards were shown off in a bad light. So,you would think they have gone to all this effort to make this new fangled measuring system,so good on them and fair enough AMD needed to fix their stuff. All sounded great until all of a sudden FCAT came out,and PCPER said they had been working with Nvidia. Then it transpired from one of the Anandtech reviewers and IIRC,Kyle Bennett over on HardOCP Nvidia had been fishing for collaborators at hardware websites to "work" with them on this.
Ever since that day,I have always been a bit careful about taking anything PCPER has to say at face value unless its confirmed by more than one source.
