An unofficial PC port of Nintendo 64's Perfect Dark is available for download, featuring mouselook, widescreen, FOV & 60fps support

They added an extended menu for all the new settings and added a special key for crouching and kneeling. They also implemented blur effects, centered the HUD option, and improved the Xbox controller support.

Definitely dling this.
But why would anyone add blur effects into a game that doesn't have it? Blur is the first thing I turn off in any game. I don't know anyone that plays with blur on. It's a horrible useless "feature".

Anywho, love a modern controls perfect dark!

Edit, from the read me:
The following extra features are implemented:

        mouselook;   
    dual analog controller support;   
    widescreen resolution support;   
    configurable field of view;   
    60 FPS support, including fixes for some framerate-related issues;   
    fixes for a couple original bugs and crashes;   
    basic mod support, currently enough to load a few custom levels;   
    slightly expanded memory heap size.

  

If it's like the Mario 64 and Zelda Ocarina of Time ports it'll be legendary. I have both on my Steam Deck and it's amazing playing both in widescreen 60fps upscaled.

Man, and I'm just waiting on a port of Eternal Darkness
