This guide will help you solve an issue with the bug that locks the game to a 60hz refresh-rate on a 144hz screen even after you disable the V-Sync in the display settings.
Mafia Definitive Edition is a remake of the original Mafia game from 2002, and it is a gorgeous-looking game. As soon as you start (re)playing this masterpiece, you’ll be amazed by the wonderful graphics upgrade of the 2020 remake.
But, as with many PC games, it’s not without some issues.
The first and probably the biggest one that will get in your way is the V-Sync issue. Apparently, the game locks into 60hz mode even if you disable the V-Sync in the Full-screen mode.
There is no Refresh rate option, just the Screen mode, V-Sync, etc. If you have a G-Sync or FreeSync compatible monitor with a 144hz refresh rate, you’ll most certainly want to disable the V-Sync and play with the highest frame rates possible.
So, what you have to do is this:
Go to your desktop and Right-click on the Mafia Definitive Edition icon (.exe)
then click on the Compatibility tab,
then click to enable the “Disable the full-screen optimization” option.
If the shortcut is not on a desktop, you can find it in the Steam folder: Steamapps, common, Mafia Definitive Edition.
If the “Full-screen optimization” does not solve it you can try with this:
Open Nvidia control panel > Manage 3D Settings > program Settings > find Mafia Definitive Edition there or add it by yourself > then scroll down to refresh-rate and set to “Highest”.
You can also set the game to Borderless (Full-screen Off, Window Borders Off) mode and you’ll solve the issue this way too, but for some gamers, the Windowed Borderless mode is not an option.
Go to the game and make sure you are using these settings:
Full-screen mode On
This should help your display to achieve 60+ fps and you can enjoy this remake of the classic crime drama in the smoothest way possible.
