Yep, SP runs pretty poorly for me, drops to sub-30 fps quite often, get weird fps drops in the menus - sometimes down to 5 fps with the cursor skipping everywhere. I'm running it maxed with medium corpses at 1600x900, which is what I run every other recent COD at and get a rock-solid 60 fps. Turned off v-sync and still had the drops and hitches. I'll mess around in the config file later and try some of the temp fixes people have come up with, see if it gets any better. If you buy it on PC you're likely going to have to do some digging around to fix it yourself until there's a patch. If you can live with that, and can wait on a patch (I am guessing there will be a SP patch within the next few days, maybe before the weekend is over), go ahead. But don't just listen to people who tell you this is fud, there are definitely problems right now, and there is more than a 50% chance it will run like shit for you. As far as recent components go, my system is a pretty common build, so the bewildered dev response to the problem strikes me as very disingenuous. This is absolutely a case of "we'll fix it later, just get it out the door."
