I'm using GTX 560ti, my resolution is 1920x1080 and graphic is Ultra with no MSAA. Dose anyone know how to fix?
This is a known issue and there are several threads on GetSatisfaction about this here and here. Sounds like both DICE and nVidia have bugs. So far the only solution I've seen is to reduce your settings to "High", no AA (deferred or post), ambient occlusioning to SSAO, and no blur. Those might need to go lower depending on a particular situation. It strikes me as a memory bus issue.
It's rather sad considering how prevalent that card is.
