Yeah, well, I'm enjoying it. And in all fairness my system is having trouble running it - I had to remove a number of APEX files to make it playable - but it now runs okay with the occasional few seconds pause. So long as I'm not holding down a key the pause passes fairly quickly
I've found that the performance degrades severely after a couple hours of playing. Likely a memory leak or similar flaw. A number of other people have reported the same behavior on their forums. Restarting clears it up. Annoying and hopefully sorted with a patch, but for the time being, it's just serving to remind me that I've been playing too long.
All things considered, I get excellent performance. On a 9800GTX and E8400, I get a consistent 50-60 fps at 1920x1080 with the details on max, but without Physx and no AA. I get occasional little stutters when I'm booking it across the city, but nothing you could take offense at.
I'm really digging it too. I dunno what the deal with that 4/10 Eurogamer review is about. It made some valid points to be sure, but seems to me that someone probably just has an axe to grind for whatever reason. I'd probably give it an 8.5 myself. It's not spectacular or groundbreaking in any way, but it does what it says on the tin very well.
My biggest gripe is that it doesn't support a wheel without jumping through a lot of preposterous hoops. That's how I played the first one and it makes the driving much, MUCH more enjoyable. I don't see how or why they left that out. Though it would be nice, I don't need fancy FFB or anything, just standard generic control configuration. Maybe they'll add that in some time, though I'll probably be done with the game by then.
Other than that, the firefights and cover system work very well, and the fistfight system works well for what it is (a little too easy perhaps once you get the rhythm down, though).
The city is fantastic looking. They did a really brilliant job with that. It's by far the most impressive looking open-world city I've ever seen. Lots of character to it and nice detail. It could use a little more variety in the pedestrians though.
Anyways... the only way I could see someone being totally disappointed in it is if they were expecting it to be something it isn't trying to be.
It is a linear game. That's perfectly fine with me. It would be great in a different way if they made a sandbox game along similar lines, but that's not what this is.
