Thanks for the advice, but everything you wrote is what I meant by "Vsync is active, fps are below 60." ^^ Tried a new save again, this time with Adaptive Vsync and Triple Buffer. Usually these are my standard settings but they got lost during driver updates. Now the ride was smooth. However just before the captains calls the prisoner, Skyrim crashed. Suspect some sort of Ram/VRam limit. enblocal settings are: VideoMemorySizeMb=4096 (made the mistake to use Win8 instead of 7) On a side note, before I knew about Skyrims "Physics" engine I had up to 100 fps. The wagon never had any problems, only random things on shelves or tables would explode from time to time. Some other thing I haven't found a good solution: z-fighting. Is there a fix to resolve this, other than hoping for a better engine on TesVI?
