it will be downgraded and yes, its being rushed but avatar was very polished. probably the most polished game last year outside of FF16.
the overall visual fidelity will be very close to this. but i suspect those final few shots of the cities are going to see the biggest downgrades. they look too good to be true.
the wind effects were present in avatar, but the volumetric effects are way beyond what i saw in avatar. avatar also has no cities with this many npcs and just little huts.
the biggest concern i have is that they used black bars during gameplay a la hellblade 2 and the order. and while that would be ok if they showed console footage, they refused to say what they were running this on so this is likely running on a 4090 which is almost 3.5x more powerful than the ps5. if they needed a card that powerful just to run it at native 4k and still needed black bars to reduce the graphics load by 40% then yes, there are going to be doubts.
I wasnt too fussed about the Avatar downgrade because they showed PS5 footage running at 4k fsr 2 quality. so 1440p. Back then i said that they will just reduce the resolution instead of removing RTGI and reducing foliage quality and thats exactly what they ended up doing. In fact, the game goes up to 1800p and down to 1296p internally so it actually improved in some ways from that trailer. But this is running on PC so who knows.
i guess we will find out in 3 days.
