Fallout 4 is a popular open-world RPG game that was released in 2015 by Bethesda Softworks. The game is set in a post-apocalyptic Boston, where the player can explore, fight, craft, and build their own settlements. Fallout 4 is praised for its immersive gameplay, rich story, and modding community.
However, some players may experience performance issues, such as low FPS, stuttering, or crashes, especially when using mods that add more content or graphics enhancements to the game. One of the possible causes of these problems is that Fallout 4 is a 32-bit executable that can only access up to 2 GB of RAM by default. This means that the game may run out of memory when loading too many assets or scripts at once.
Fortunately, there is a way to fix this limitation and make Fallout 4 large address aware (LAA). This means that the game can access up to 4 GB of RAM on 64-bit systems, which can improve stability and performance. To do this, you will need a tool called 4GB Patch, which can be downloaded from NT Core. This tool can patch any 32-bit executable to make it LAA.
Steps to Make Fallout 4 Large Address Aware
Download the 4GB Patch from NT Core and extract it to a folder of your choice.
Backup your Fallout 4 executable file (Fallout4.exe) by copying it to another location. You can find it in your game installation folder, usually C:\\Program Files (x86)\\Steam\\steamapps\\common\\Fallout 4.
Run the 4gb_patch.exe file and browse to your Fallout 4 executable file (Fallout4.exe). Click Open.
The tool will patch the file and display a message saying \"The file was successfully patched!\". Click OK.
You can now run Fallout 4 normally and enjoy the benefits of having more memory available.
Tips and Warnings
The 4GB Patch is a generic tool that can work for any 32-bit executable. You can use it for other games that have similar memory issues, such as Oblivion or Fallout 3.
The patch is reversible. If you want to restore the original executable file, simply copy the backup file that you made in step 2 and overwrite the patched file.
The patch may not work for all games or with some mods or launchers. If you encounter any problems after applying the patch, try disabling or uninstalling any mods or launchers that you are using and see if that helps.
The patch does not guarantee that you will never run out of memory or have performance issues. It only increases the amount of memory that the game can use. You may still need to tweak your graphics settings or use optimization mods to get the best performance possible.
The patch does not affect your save files or achievements. You can continue playing with your existing saves and earn achievements as usual.
