There's absolutely nothing wrong with my vision, and continuing to just insinuate there is, I find a particularly weak argument. Seems much more likely that there is a configuration difference in your drivers, game settings, windows monitor settings etc, some explainable difference, between GeForce and Radeon systems and config you've tested. I've not seen anyone able to demonstrate this difference conclusively in well over a decade, where it wasn't attributed to configuration differences. So based on that, what I've seen myself, and what the broader community and tech press have found, I'm yet to see anyone actually demonstrate Radeons just generally providing a clearer and sharper image. Want to link me to the bang4buck video/s you mention? I'll happily take a look. I'd appreciate it if you stopped insulting my vision, it's not a path to proving anything, and isn't the argument winning approach you might think it is.
I thought it was known and accepted at this point, but every so often someone comes along, insists there is, but can't prove it. It usually either falls apart fast when attempted to be shown, is explained by configuration, or is just trust me bro. I'm a reasonable person, and will take on new information and allow it to alter my knowledge and beliefs if it's reasonable, compelling, conclusive etc, I'm yet to see it though.
