When I'm playing on the Japanese version of VC, the mouse is just spinning all over the place (yes, I am using dinput) but on International version, the mouse works fine. I tried a lot of solutions but nothing seems to fix it. Help would be appreciated.

check game/dxwnd resolution just in case

Tried changing DXWND res that didn't work. I also did a fresh reinstall on my Vice City and deleted my entire user files.

saw this comment in discord, maybe it could help: “I had this bug where the mouse just spins when trying to move it even when I had dinput8, I fixed it by going into properties > override high dpi scaling by application”

That doesn't seem to work either. I wonder why my game is doing this now, it never did it before until now

I fixed it now. Playing without dxwnd stopped the bug
