The video isn't official?
It is, and their official analysis is that the game runs predominantly at 40-50fps
Do you really think that their entire framerate analysis was only 5 and a half minutes?
This should really not be that difficult to understand.
They cherrypicked moments of the game for the video. The video that's mainly 50-60 fps. Why not show the areas where the fps was 40-50?
Okay so you're admitting that the video is not the best measure of the framerate, rather the stated frame rate in the analysis is more accurate
Glad we cleared that up
