BTW when i installed i saw a notice "you have dual core ... there are issues"
You mean SLI, right? If so, the patch just got released, as Paddy mentioned.
For those of you playing this right now, how does it faire with widescreen resolutions? Smooth play, or a little slow now and then?
It fairs like you'd expect any game new game to run at high resolution. If you run into a GPU bottleneck, the game scales down fairly well, but I really hope you don't have to do this, at least for the terrain and model textures. But if you have to, the game will run smooth and you can still enjoy the great gameplay. For instance, when running in triplehead, even with just a 7800 I can just drop down the features and it runs fine. But instead I just opt to run in 1280 until I get things figured out.
Great game, highly recommend it (You too, North).
EDIT: As far as framerates go, the game is more than playable at 30+ fps, imo. Try the demo to get an idea of performance, tho the full game may run a tad slower, keep in mind. You can always "try before you buy" of course...
