| Sorry, no help here. The only similar problem I've seen is choppy sound/motion which turned out to be my graphics card drivers.
For your issue I don't know what to say, but if your graphics card drivers are up to date (and old versions are removed) then I think it's a bug with the game. Have you tried uninstalling, deleting all the files and reinstalling to see if there is just a corrupt file in your install? |
