This. There's a reason I stick to high hertz 1440p instead of going for 4K. I don't even consider the 2080 ti as a fully viable 4K card, at least for my needs.
It really isn't, but it's the best option out there today. It's viable for some games, but not others. For example: Destiny 2 runs pretty good most of the time even at 4K. However, you will still struggle to maintain a 60FPS minimum at times. I actually moved off of 4K to 3440x1440 to make my experience better in newer games.
Except I still found FarCry fun after the mutants appeared, they kind of mixed it in with the soldiers, the rebellion map was great in farcry. The only bit that was actually on rails were the last two maps.
Crysis however seems an entirely different game after crossing that line, and arguably that line is much earlier.
Besides I've never liked the nanosuit one bit. It's a distraction at best, gimmick at worst. I used it when it was a must, but otherwise it did nothing to improve my game experience.
I'd like to think the reason they're remaking Crysis and not FarCry is because FarCry rights are owned by ubisoft now.
I will agree that for the time, FarCry was the better of the two efforts looking at each game as a game and not the fancy tech demos each of them were at the time of their release. That said, I really like the early part of Crysis. I would often play it up to that point and then start the game over. Once the aliens showed up, it was totally different and rather unremarkable. The sequels were better on that front. I actually rather enjoy Crysis 3.
