MARKED ONES! I have good news...
Alright so first impressions, I am 87 mins in just past the 3rd scanning point, done that bit and watched the cutscene and now on the way to the next waypoint. So far I've done some combat, roaming around, indoors/outdoors, anomalies, monsters, looting - Classic Zone shenanigans.... Zero stutters, hell even at 4K with DLAA I can get 45-55fps but there's no reason to use DLAA on this as per previous comments since it is UE5 and works best with an upscaler.
DLSS Quality is perfectly fine but then DLSS Performance looks the same so no reason not to use that for the extra fps. I can see up to 91fps average without Frame gen here and averaging 77fps. With Frame Gen it's 100fps+ mostly. Frametimes seems smooth. The game defaults to Epic settings and there's no way to turn off motion blur only set it to low so an Engine/ini tweak may be needed as is usual for UE5.
Not encountered any bugs yet either so am assuming all of these reviews saying bugs and stutters/fps drops were exactly as I assumed earlier today, that they were played and recorded pre-patch.
the audio is awesome, the cinematic quality of the cutscenes and general action and mechanics I am enjoying more than the OG trilogy. The controls need some getting used to but that's fine.
Mouse sensitivity by default is way too low, 12%?! I whacked that uyp to 60~ and aim sense was also too low, now 35.
Full screen vs Windowed Fullscreen vs Windowed is glitchy though. Fort some reason in Windowed Fullscreen the game renders are a pseudo resolution (3072x1728), but put it into Windowed mode or Exclusive Fullscreen and it is at normal 4K - Weird.
The black levels are perfectly black even in SDR mode, and I can see there being room to tweak this to near perfection though I have not played with the settings for brightness/gamma yet. Everything feels nice and polished in-game though.
So far it has beaten the expectations I had after seeing the first reviews pop up earlier today. Let this be a lesson to all that reviews aren't exactly to be fully trusted and I think this is why they enforced the tight review window because if the reviews came out a week ago, a whole load of people would have cancelled their orders no doubt, at least 2 hours beforehand people can try it out and refund if needed, but as it turns out, that is not needed for the most part.
Excellent stuff.
Regarding Frame Gen, FSR 3.1 Frame Gen is not as performance+ as DLSS Frame Gen. I clocked the game fps just below 100fps with FSR FG, but well over 100fps with DLSS FG.
For ref I am running a 12700KF, 64GB DDR4, 4090 and 4K 240Hz OLED. I watched all the reviews earlier today of reviewers with 4090s stating all the performance issues and bugs, and fully expected this too but hey, here we are with none of those issues lol.
There are invisible monsters that chuck stuff at you, the first encounter is in that building you scuff through to get to the other side. Just run away
