Metal Gear Solid Delta: Snake Eater – How to Disable the 60 FPS Lock on PC

1

Metal Gear Solid Delta: Snake Eater is shaping up to be a highly anticipated return to one of the franchise’s most iconic chapters. While the game promises modern graphics and refinements, its PC version has shipped with a 60 FPS lock, leaving players searching for a workaround. Thanks to community findings on the Steam forums, there is now a method to lift this restriction without causing the dreaded slow-motion or double-speed issues that plagued earlier tweaks.

This guide breaks down the process for removing the FPS cap. Credit goes to community contributors who experimented with different approaches, eventually settling on a UE4SS-based solution that forces the game to accept higher frame rates.

Step-by-Step Guide to Disabling the 60 FPS Cap

1. Install UE4SS with Compatibility Fix
   • Download the UE4SS ZDEV build with compatibility fix from GitHub:
     UE4SS Fix
   • Extract UE4SS to:
     \common\MGSDelta\MGSDelta\Binaries\Win64
   • After installation, the folder structure should resemble this example.
2. Create the Mod Structure
   • Inside UE4SS/Mods, create a folder named UncapFPS/scripts.
   • Place a new main.lua script inside that folder with the following code:
   RegisterHook("/Script/Engine.GameUserSettings:ApplySettings", function(self, bCheck)
   self:SetVSyncEnabled(false)
   self:SetFrameRateLimit(0.0)
   print("[UncapFPS] ApplySettings -> limit forced")
   end)

   RegisterHook("/Script/Engine.PlayerController:ClientRestart", function()
local gus = FindFirstOf("GameUserSettings")
if gus ~= nil then
gus:SetVSyncEnabled(false)
gus:SetFrameRateLimit(0.0)
gus:ApplySettings(false)
print("[UncapFPS] ClientRestart -> limit forced")
end
end)


3. Activate the Mod
   • In the Mods folder, edit the following files:
     • mods.txt:
       UncapFPS : 1
     • mods.json:
       {
"mod_name": "UncapFPS",
"mod_enabled": true
}

4. Adjust Engine.ini as a Backup Measure
   • Navigate to C:\Users\*YOURUSERNAME*\AppData\Local\MGSDelta\Saved\Config\Windows and edit Engine.ini.
   • Add the following lines:
   [SystemSettings]
   t.MaxFPS=0
   t.AllowFrameRateSmoothing=0
   r.VSync=0
   rhi.SyncInterval=0

   [/script/engine.engine]
bSmoothFrameRate=False
MinSmoothedFrameRate=0
MaxSmoothedFrameRate=0


5. Verify That the Mod Is Active
   • Launch the game and check the UE4SS logs. They should confirm that the uncapping settings are applied.
   • For visual reference, logs should appear similar to this example.
6. Optional: Disable the Debug Console
   • To ensure Steam overlay compatibility, disable the UE4SS debug console through its settings file. Here’s how it looks.
