Nothing is going to be proven, since you fundamentally dont understand that these requirement sheets aren't as carefully curated as you seem to bizarrely think they are. In all the many, many years of PC gaming, these have NEVER been accurate, but you still seem to think we can actually use this specific one as a reliable judge of some specific variance between GPU performance between AMD and Nvidia.
I am honestly bewildered at how PC gamers could have never, ever learned anything from the past thousand times they weren't accurate, while treating every new requirement listing as gospel. It's absolutely insane to me. Like, I genuinely dont grasp why other people's brains dont seem to work.
