Unlimited Menu FPS

Description

Unreal has a setting that limits the menu frame rate to 62fps, but luckily we can make some edits and fix that.

Installation instructions

This is a simple edit to the following file:    %UserProfile%\AppData\LocalLow\MCC\Saved\Config\WindowsNoEditor\Engine.ini

You can download my archive and unpack it in location mentioned above.

You can make the edits yourself:

1) Open the Engine.ini file in a text editor, like vscodium.

2) Add the following lines:

bSmoothFrameRate=True

bSmoothFrameRate=False

  Why are there two? Because when we add this boolean and toggle it to FALSE, the engine will add a second copy of this line and toggle it to TRUE at runtime, re-enabling the fps cap. This is gonna seem kinda dumb but the fix for that is simply to swap those two lines.

3) Save and do not set the file to read-only.

READ This tweak does not require read-only locking the Engine.ini file and it may not even work correctly if you do lock it.

This is might be why this tweak has taken so long to be found. If you attempt to edit the file yourself, and if you only add the 1 line, and if you read-only lock the file, the tweak does nothing. If you simply save the file and leave it unlocked, the engine will behave as described above.

How did I notice this happening? It was largely unintentional. I had left the Engine.ini file open in vscodium while I ran the game and I noticed that I could actually watch as the engine was actively writing stuff to this file at runtime and some of it may not stay there when the game closes.

Main features

It uncaps Halo MCC's menu frame rate.

However it does NOT disable the menu's Vsync and this is also NOT configurable through the game's UI. Luckily, we can fix that too.

How to disable the menu's Vsync

1) Add the following lines to the same Engine.ini file:

  Why are there two? Same reason as above.

READ This part of the tweak isn't really recommended for gameplay as there's not much need for your menus running at 300fps, but try it if you want. I used it for my screenshot.

Requirements

The game and a bit of reading.
