Really want to like this game, but it's got a couple serious issues.
1. Performance. It actually runs fine on my PC (3440x1440 @ high settings... but this is offset by a poor FSR implementation and completely non-functional framegen). There's no stuttering at all though. Series X is a different story. Balanced (40fps-120Hz container) mode has poor frame pacing. Performance seems to as well; I can't tell if it fails to hit 60 fps all the time or not because it too uses the 120Hz container. Didn't try quality at all since there's no way I'm playing a game like this at 30 fps. All modes require running uncapped fps mode on my LG OLED. If I run it capped it causes the worst VRR flicker I've ever seen and also it screws up the 120Hz container causing the TV to dip to 80 fps at times. Unfortunately uncapped modes have some occasional tearing, suggesting that VRR isn't actually working with that setting.
2. Pay 2 win. The Game Pass version is completely barebones and doesn't even come with the extras included with the $50 edition, and also none of the pre-order bonus stuff. Deluxe version includes a bunch more weapons and armor sets. None of this stuff is accessible through normal gameplay, and from what people who've completed the game have said there really isn't much gear to be found in the game so the stuff in the DLCs is actually significant percentage of the total gear available in the game. It also isn't junk you use for an hour and then throw away; it's some of the strongest gear available at least up through mid-game, especially the preorder "axe" and the deluxe ed. caster sword. I should mention that you can upgrade the Game Pass version to deluxe, but at least according to the store page that will not get you the preorder stuff or the missing items from the $50 edition. It's strictly the stuff that comes with deluxe, nothing more.
I'd just stick to playing it on PC, but an even worse problem than the performance/image quality is that it completely shut off my PC after playing for about 60-90 minutes. I don't know what exactly happened since it left nothing in event viewer, but it's bullshit when I can play Cyberpunk on mostly ultra settings with RT on for several hours at a time without any issues.
