Mafia Definitive Edition stuttering?

i know this is old but i came across it trying to find a solution but couldn't find any, anyhow, i found the solution on steam, the problem is from the crappy 2k launcher and the game doesnt utilize your CPU properly, it only stresses one core, i have 5950X and all cores are drinking tea except for core0 is 100%, anyhow, to get rid of stuttering, do the following:

  1. Right click on game shortcut and select properties
  2. Set the target as written below (you may need to change the path before Mafia3DefinitiveEdition.exe) :

"C:\Program Files (x86)\Mafia III Definitive Edition\Mafia3DefinitiveEdition.exe" %command%

This will disable the crappy 2K launcher and reduce stuttering.
3. Set VSync to On in game even if you have G-Sync or FreeSync monitor, this crappy game doesn't utilize any of those.
