These were uploaded to multiplayer.it and were posted on reddit/resetera, they are supposed to go up next week on multiple sites with previews from a 3hr demo and possibly a new trailer according to Dusk Golem.
The videos are 60fps, as far as I know RE2 on the Pro/X consoles has the option to choose between 1080p/60fps and 4k/30fps, in one of the preview builds the game ran with an unlocked framerate on base ps4 and it dropped to the 40s, but it's been several months so we don't know how the final version will run.
If the game runs at a stable 60fps on pro then I think it'll be quite promising and will be a looker if you have the hardware. DMC5 is 60fps on base ps4 and that game looks goooood.
Play quickly and carefully if you want to see the end of the demo, and be sure to pick up any useful items you see laying around while conserving your ammo. It may be tempting to try and defeat every zombie that stands, or crawls, in your way, but sometimes it’s better to use a few bullets to make an escape route than empty a clip on a monster that refuses to stay dead.
No matter how your demo ends, you’ll get to see a brand-new trailer exclusive to the demo when it’s done, giving you another taste of what to expect from Resident Evil 2 in just a few weeks.
