I finished my first playtrough and now I'm waiting on performance improvement and stabilization of the game. It will certainly come. I would bet on the fact that the game will be perfected by the time the first expansion comes out, but if not, imminent enhanced edition (2.0) will do it (I know they said there won't be an enhanced edition, but let's face it, there certainly will be).
Patch 1.07 did kill performance a bit, specially in Novigrad which is now almost unbearable, but they certainly didn't do it on purpose. With 1.08 we can at least expect reversal to the 1.05 performance. It's CDPR and I'm sure they won't leave this game behind until they are happy with how it performs, and they certainly aren't happy right now. I can only imagine the depression that is present in their offices and it hinders their ability to repair the game. And to all you guys who are bitching about the fact that you paid 60 bucks for this game, I say this. Yes you did, but your bitching ain't helping anybody so fuck off. And don't give me that "they already took our money so they don't care" bullshit, they are independent and small studio so bad press and word of mouth can literally end them.
There certainly are games that run fine on the ps4 (Batman: AK...), but the system is seriously underpowered, and it will only get worse. GTA fuckin'5 on ps4 had serous fps problems where the framerate would fall to around 23 on every intersection in the city. They drastically improved it 4 MONTHS after the release, but it still ain't locked to 30. I don't know if there is a studio with bigger budget and more people than Rockstar, and even they have problems. I think it's because of the weaker CPU in ps4, even related to xbox one. Even gods at Naughty dog can't lock last gen game to a constant 60 fps and they have whole ICE team working for them.
I'm not saying CDPR aren't to blame, because they are, but Sony and Microsoft fucked this generation up royally.
