People playing Metal Gear Solid Delta have noticed that the game locks the frame rate to either 30 or 60 FPS. And while this isn't the end of the world, as it ensures stability, a lot of people have super-powerful systems capable of high refresh rates who want to take advantage of their hardware. Thankfully, the community has created a tool called MGS Delta Fix that removes the FPS cap, adds ultrawide monitor support, and even lets you skip intro logos. So in this guide, we'll take you through all the steps you need to follow.

Takeaways:

  1. Learn how to uncap Metal Gear Solid Delta frame rates
  2. Add Ultrawide Support to Metal Gear Solid Delta

How to Uncap FPS and Add Ultrawide Support in Metal Gear Solid Delta: Snake Eater

This fix works best on Steam for Windows. If you are playing on Steam Deck or Linux, extra configuration may be required, such as adding parameters to your launch options.

Note: Support for non-Steam platforms may be limited. For the latest troubleshooting and compatibility updates, check the Issues tab on the project’s release page.

  • The first step is to download the mod from the official release page.
  • Go to the project’s release section and look for the latest version. Avoid downloading the source code; instead, download the zip file that contains the compiled fix (for example, mgsdeltafix.zip). Save this file to your computer.

  • Next, you will need to extract the mod files into your Metal Gear Solid Delta installation folder. To do this:
  • Open Steam and find Metal Gear Solid Delta in your library.
  • Right-click the game title, hover over Manage, then select Browse local files.
  • This will open the root folder of the game. From here, go to: MGS Delta > Binaries > Win64
  • Open the downloaded zip file. Inside, you will find several files.
  • Drag and drop all of these into the Win64 folder mentioned above. If you see a file labelled “extract to game folder,” you can ignore it as it is only a reminder of where the files should go.

Configure the Mod (IMPORTANT)

After installation, open the file named mgsdeltafix.ini using Notepad or another text editor. This configuration file allows you to toggle several options:

  • Developer Console (default: off)
  • Skip Intro Logos (default: on)
  • Uncap Frame Rate (default: off)
  • Ultrawide Support (default: enabled)

To enable FPS uncapping, change enabled=false to enabled=true under the frame rate setting. Save the file when finished.

Adjust Launch Options, then Start Playing

Before launching the game, it is recommended to force DirectX 12 mode. In Steam:

  • Right-click Metal Gear Solid Delta.
  • Select Properties.
  • In the General tab, find Launch options.
  • Type: -dx12

This helps with crashes and improves stability, especially when using mods.

  • Start Metal Gear Solid Delta as normal.

If the mod is working correctly, your FPS will no longer be capped at 60. On ultrawide monitors, the game will also display properly without stretching or letterboxing. Performance will vary depending on your hardware, but many players report frame rates well above 100 FPS when settings are adjusted.

Known Issues?

There are some potential problems with removing the FPS limit. Certain areas or boss fights may have physics tied to the frame rate. This can occasionally cause soft locks or glitches. To avoid permanent issues, it is recommended to save your progress before major events.

If you have any problems:

  • Open the mgsdeltafix.ini file and disable the FPS uncap by switching the option back to false.
  • Alternatively, remove the mod files entirely from the Win64 folder.

This will restore the original 60 FPS cap and eliminate mod-related issues.
