Perhaps he assumes that H hasn't ever tried Fury at 4k even though the site preaches max playable settings.
Their site goes for max playable settings like you said. Why would they display 4K settings which would NOT be the max playable settings? It's clear they go for highest settings at the highest resolution possible. Clearly, HardOCP would NOT consider 30 FPS playable at 4K or anywere near 30 FPS. HardOCP considers sometimes even FPS that is acceptable to me to be completely unplayable.
HardOCP's sometimes has periods of times where there are gameworks titles in the mix (due to how HardOCP picks their game selection), so it doesn't count. When HArdOCP has a lot of GE titles, then Fury X/Fury will be talkd about how great they do in those reviews I bet....
Those are some pretty harsh words against HardOCP as a bench site it's not my go to first stop, but I definitely read each review they post.
