Got it on PC yesterday.
All Ultra, 1440P, never once dropped below 35fps. 50-55fps was the average on my 6~ year old PC.
60fps fully locked with the old 3930K @ 4.8ghz.
This game is brutal on the CPU, it does seem to use around 8~ CPU threads, but pegs one core higher than the others... It's no wonder the consoles are struggling with this though as the 8-core Jaguar is only a fraction of the power.
I found the game itself though to be extremely ugly, even on Ultra settings, could only imagine how bad it looks on the Xbox One and Xbox One X which I might get at a later date once the shiznit is ironed out.
Its one of the ugliest games I've played on X1.
First of all, there is some really bad pop in issues. Muddy textures take time to load or simply don't load properly. When skydiving the map itself appears to be missing textures, jarring pop in, etc. While exploring the map I though I ran into some horribly designed burned building, but after awhile a normal building just popped in while I was in it.
Even when everything is loaded properly, the game is still kinda ugly. The textures look like last gen and shadows on surfaces are low quality and are essentially dots. It seems when you look closely at everything, it just looks bad. The game probably looks its best when you're exploring an open area with lots of foliage and it looks crisp because of 1080p.
If we're going by average though, the game generally feels like 30 fps.
I can't help but think they should have stole the idea of PUBG and use Gears or Halo. It would be a better game and no marketing deal required! But I guess that's what MS paid for, a big name title to boast about for awhile. It may have been worth the money as well because people are certainly buying it.
