To those of you who have Killzone 1 HD

Did the devs bother to iron out the framerate and little graphical glitches it had? Or is it the exact same ol' ps2 Killzone with slightly enhanced graphics?

Did they fix the occasional button lag too?

I heard that they were putting in work to the HD collection, suppose-ably they were making it playable and smooth. BUT then the game came out and I heard a few people saying that it was still a crappy port, but I havent heard anything about the game's performance from any reliable sources tho. So Im wondering too...Nengo_Flow
