Game runs ok at Native 4K with everything maxed out on a 4090, didn't see a lot of dips below 60.
I highly recommand this YT channel, this guy always deliver quality videos on different high end cards without shenanigans.
No texture streaming issue as well, don't know what was up with Alex version.
Rich also had issue before the test I believe, didn't he say he had to replace 2 motherboards before beginning the test?
I don't mind these 3 ways comparative videos with John, Alex and Rich but I think they should come AFTER the proper deep dive analysis video we're use to see. These look like they're put together in a hurry, without much preparation and with everybody at home, etc... it's just not the best first look you can give to a big new game I think.
