Problems with NFS Undercover

[Windowed]

I installed NFS and I have lag problem and graphics problems. Yesterday I had scanned for viruses but no effect, still the problem exists. There are zigzag lines across the screen. I tried to change the resolution but no use. Any advise will be highly appreciated.

Without knowing your system configuration it is really hard to figure out what your problem may be. Plz specify your system configuration, so that I can try to help you out.

It looks a pretty good configuration.
I think your graphics card is bit old, plz try upgrading your graphics card, its shouldn't be expensive. If you have a LCD, try to find it's resolution and set it to the games resolution for best results. If any problems do reply back...
