Except he really is pretty accurate in his analysis barring the so-called "uprendering" patent while isn't upscaling, but it's not checkerboard rendering, either, and has no bearing on the PS4 Pro except when running emulated PS2 titles. If you squint they look similar but that's true of a ton of other unrelated technologies, too.
The constant "I was right and they were wrong" / "I'm such a genius" nonsense is every bit as toxic. Yes, people started piling on unnecessarily when it became obvious he was out of his depth. This shouldn't be a blood sport but it would help if onQ would give up the act and accept that he's an avid hobbyist with a keen interest, and not someone who actually works in the field and has a background in the subject matter. There are plenty here who can recognize when he's just flinging terminology around that he doesn't really understand.
