New video card keeps on jerking in mcm2

[Vern]

I just bought a Geforce fx 5700 256mb and when I play Mcm2 the frames keep on jerking. I used to have a Ati radeon 9000 128mb and it wasn't doing that. Can anyboby tell me why it does that and what I can do to fix it.

Thanks.

make sure your drivers are up to date. and check your video settings, if they are similar to your radeon settings were
