That looks like a driver problem. Have you tried uninstalling/reinstalling the 9.12s or the new Hotfix driver?

nop, but you sure that driver problem ? Maybe bad card?

You said your other games ran fine which seems to point to only a problem with Warhead.
Those lines appear if there's a driver problem. Here's a link to the 9.12 Hotfix driver if you want to try them to see if it cures it.
