[LASE]

So I hope someone can help me I have a problem. My problem is this I recently bought a new computer it was an HP and I know some people will say that is my problem but putting that aside I bought this computer, it has 2G Ram an Nvidia 7300 graphics card a core 2 duo processor and I have cable internet but with all this CODUO is still not running well for me I'm not really seeing a lag (I am in COD2 but that's a story for another post) it just seems to stutter a little sometimes when I run it just like I said stutters and when I come out of a run to react when I see someone my weapon does not come up as fast as I would like it to. I know I usually put up good numbers (I almost exclusively play MWCM) but I just think they could be alot better if it were not for this problem. I kind of hope Steel will see this because that's who was helping me with my original problems but anyone's suggestions will be most welcome. I already posted this in general discussion but I thought I might get a better response here.
