ok i didn't really know where to post this so...
anyway, i got CoD WAW and MP runs fine but SP is very choppy. I have a Nvidia geforce 8500 GT video card. what i want to know is why it runs choppy. Could it be couse my card isn't good enough or what? I'm not really interested in CoD WaW though. i want to know how CoD MW2 will run. cause if cod 5 wouldn't run good cause of my video card cod mw 2 definantly isn't going to.

I don't think there's much of an upgrade in graphics in CODMW2 in fact they have increased performance now with texture streaming. (if my understanding of texture streaming is correct)

MP and SP don't have any real differences in terms of graphics but I think by default the games graphics settings for both modes are different.

For a good performance test, check your FPS with and without dynamic shadows and specular mapping.

These are the main offenders, other features like dynamic foliage can be turned off but the server (in SP YOUR machine) still records the state of each foliage model (destroyed or not) so I don't think that will make a drastic change.

I had 2 7800GTX cards and they were perfect, but one blew up and I now have a single 250GTS 1GB which does the same job just fine, anything the same or higher will run MW2.

I would have to question if it is even a video card issue since the mp runs ok and sp runs like crap. You need the disc in for sp so my question to you would be more like what is the rest of your hardware doing? Have you defragged the harddrive lately? What are the actual specs for the machine beside the video card?

awesome! i was just talkin about defragmenting about an hour before i saw your post. i did it and the game runs great for hte most part. although it still doesn't like the flamethrower
