Considering all CoDMW2 is a port from consoles, offcorse it has low requirements
18 Player max
Hosted of your OWN computer using RTS system
aka if one person has a crap computer, whole game lags
most likely a capped fps
no console
no dedicated server
no lean
If you buy it, itll lag either way online but if ur looking for single player... $60 in this economy is a bit too pricey eh?
Me myself? I had it preordered, cancelled it. Got all my friends to not buy Console + PC version of it? How? I showed em the style of us pc enthusiast and our computers and our type of gaming and they loved it to death.
Thats my rant, but I'd say ATM if you still want it
grab an ATI 4850/70 or an GTX 260 for cheap. Both will be quite an upgrade but easy on ur wallet (and can play any game on high settings atm) and you can just replace it later on when DX11 is matured (itll last a year on high settings then medium)
