It is this Windows update: Platform Update for Windows 7 x64-Edition (KB2670838) I am running an older system and directX10. I do not know if this update will effect DX11 systems but for sure it screwed up mine. It is an optional update, So just uninstall it' Problem fixed. Update realesed 2/27/2013 To uninstall an update open controll panel/ programs and features/ uninstall a program in the left panel select veiw installed updates then find this update and uninstall. (note) if you get an error when uninstalling it restart you computer and try again. the error is caused by a pending restart needed, related to thes update or not. Go wobbly windows!
