I know but most people don't seem to care about this huge difference in "power consumption" when they compare 30fps games with 60fps games. 

The drop in frames is compared to how much stuff is going on. If 24 guys throw grenades at one time, it will drop a bit. Don't expect anything crazy in terms of drops if they are going for 60 FPS.

edit: bad post

What are you talking about? The game was 30fps... now they are optimizing for 60fps in MP because the players asked.

BTW the campaign runs at 30fps.

Yea sorry I was refering to the Campaign, I dint read ur post good cuz i was little bit shocked what was highlighted

But the Demo campaign runes smooth in 60frames

Wondering - if they had those extra 700GFLOPS some 3rd parties were expecting for next-gen (for 2.5TFLOPS total), so they can really have locked 60fps with visual fidelity as it is in current build, would they go with that or would they go for even more effects and 60 fps "a lot of times"?

The multiplayer demo runs at 60fps... the campaign demo runs at 30fps... and yeah it is smooth.

2.5TF? It's more 1.96TF with CPU included... GPU only 1.84TF.

My poor source has already been udpatedXD

(Sony just sent us this new Killzone: Shadow Fall trailer, and it's a 60 fps version!
Update: This of course doesn't mean that the actual final game will run at 60 fps!)

my bad

Edit: google is screwing me up, everything I said here can be considered bullcrap, Iam misinformed about KZ SF, I will do more research about stuff in the future I dont own.

Lol I think it's the first time Guerilla works with 60fps and didn't check how other developers achieve 60fps. I'm really yet to see a game on consoles that does not drop frames at all, and a lot of them if not the majority run slightly below the 60fps benchmark most of the time. Yet every developer states that their game runs at 60fps.
So no need for excuses Guerilla, cool you want to be honest, but everyone does it.
