Perhaps the Switch version has something extra somewhere? It might add something to the save. If you're actually able to get the files over (for some reason I can't) maybe you could compare via the savetool app. Copy a PC save over, run the game, immediately hit save and exit, then compare the new Switch save file with the old PC one. There shouldn't be a lot of difference between them, so you probably won't find a lot. It may be just a matter of zeroing something out. EDIT: Come to think of it, it probably puts the configuration stuff that the PC version puts in an INI file inside the save somewhere.
How do you disable the 60 FPS lock? Does it break anything to do so? (A lot of games start messing up various scripts and stuff if they are built around a FPS lock and break things if you change it.)
How strange. I tried to copy my PC save over using this exact method and it produced an error instead ("Could not prepare saved data. Returning to the title screen.") Did you only just rename or did you run it through save tool or something along the way somewhere? I noticed the files looked a bit different, so I was wondering if it was encrypted or something.
EDIT: From the other thread I came up with an idea. Using ddsavetool I extracted the save from the PC version, then I repacked it and loaded that on the Switch. I have no clue
WHY this worked, but it did work. And of course I'm severely overencumbered due to lacking the weight mods, lol.
I started this thread to hopefully discuss the process of maybe getting those ARCs extracted and repacked after modification:

The short of it seems to be that the Switch port uses a different compression on the files within the ARC files themselves, but the basic structure of the PC version's ARC files (probably.)
