Developer Fumi Games has released another update for Mouse: P.I. For Hire, and it’s a big one.

Not only does Version 1.2.0 target a huge amount of bugs, but it also adds in some neat new features. First up, it adds uncapped VRR for compatible devices, which should result in better performance. in addition, a new ‘balanced’ 40fps mode has been added.

You can also now revisit levels you’ve previously beat in order to mop up any incomplete side quests, and UI elements have also been improved, including the ability to view weapon enhancements in the weapon wheel. Nice!
