Ok, I will try in a lil bit. and let you now.

Thats strange your game should't lag with those comp specs.
I got pretty much the same equipment and not even half your RAM.
However i got a better graphic card(Radeon 4800).

Maybe you need to patch your Nvidia card or something. Playing MoW with lowest settings isn't fun. You lose alot of the magic...

Got the Nvidia card all up to date :/

I played MoW at maximum with a similar Intel Q6600 + 8800GT + 4GB RAM system so I doubt it is your hardware, as mentioned above try updating your video drivers and audio drivers. Also make sure to turn off all unnecessary apps running in the background just in case. And if that doesn't help, you might want to test it under Windows 7 (preferably on another unused hard drive). Don't forget you can install and run Windows 7 for up to 30 days. ISOs are available from Microsoft.

UHHM, AMD phenom 2.2 is pretty crap at games that barely use even two cores.

I'm pretty sure it's his processor.

Hey, did turning down 2 minimum graphic settings work or not?

I have had that alot about My processor being the thing that lags me down...But on games like Arma 2 for instance, needs alot more then what mow needs...And I can play that on medium settings and get pretty much no lag, unless there is tons of explosions and stuff lol.

Another thing is...I have COH, and it runs perfectly fine on high/medium settings without any lag at all, and that is pretty much the same as mow Recommended system requirements wise.

So I'm just wondering if MOW doesn't like Vista? (I'll give that windows 7 a try here in a little bit)

Also, I did turn my settings all down to low...I mean of course it helped out performance wise (would on any game), but looked really shitty :) lol.

EDIT: another thing I forgot to add, The Demo of mow was smooth as can be...without all the patches and such, and I turned my settings exactly the way it was on the demo, but I got lag?...Could there be something wrong with the patching? possibly? I know they have a hotfix for 1.17.5...I downloaded that but it doesn't say that it is 1.17.5.1 in game??? should it be like that? or did the hotfix not get patched correctly.

I play MoW on Vista and it works fine...

Well I mean it works fine also, but idk why the demo runs smoother than the Actual game itself lol.

I play MoW on Vista-64 on the highest possible settings, no problem.

I think it still says 1.17.5 with the hotfix.

Hmm... you should try experimenting with the settings. Removing useless crap like shadows sometimes help. AA is also very demanding.
