Crashes outside Falkreath are common even in vanilla. It is a very VRAM, RAM, and CPU intensive area. That said, are these crashes 100% reproducible every time you approach that area. Or are they more sporadic? If the former, then it is likely a direct conflict or missing mesh. If the latter then it' may be VRAM overload or something more subtle.Have you tried monitoring memory usage in that area with GPU-z or a similar tool?
