How to Fix Diablo 4 High RAM Usage on PC

Diablo 4 is an incredibly immersive and visually stunning game. However, it's no secret that it can be quite demanding on your system's resources, especially when it comes to RAM usage. Experiencing high RAM usage can lead to performance issues, lag, and even crashes. But fear not! In this blog post, we will explore various methods to fix high RAM usage in Diablo 4 on PC, allowing you to enjoy the game without any hiccups.

One of the first steps you can take to optimize RAM usage in Diablo 4 is to adjust the in-game settings. Lowering certain graphics options, such as shadows, anti-aliasing, and particle effects, can significantly reduce the strain on your system's RAM. Experiment with different settings to find the right balance between performance and visual quality.

Outdated or incompatible graphics drivers can often be the culprit behind high RAM usage in games. It's crucial to keep your graphics drivers up to date to ensure optimal performance. Visit the website of your graphics card manufacturer and download the latest drivers for your specific model. Installing these updates can help alleviate RAM usage issues and improve overall performance in Diablo 4.

Developers regularly release patches and updates to address various issues, including memory-related problems. Make sure you have the latest version of Diablo 4 installed on your PC. These updates often contain optimizations and bug fixes that can help reduce RAM usage and enhance gameplay stability.

Corrupted or damaged game files can contribute to high RAM usage in Diablo 4. To resolve this issue, you can verify and repair the game files through the game launcher or platform (e.g., Steam). This process will scan the game files for any errors and replace or repair them as necessary, potentially resolving memory-related problems.

Running multiple background processes simultaneously can eat up a significant amount of your system's RAM. By closing unnecessary processes, you can free up valuable memory for Diablo 4. To identify and close such processes, open the Task Manager (Ctrl + Shift + Esc), go to the Processes tab, and sort by memory usage. Close any non-essential processes that are consuming a substantial amount of RAM.

Virtual memory, also known as the page file, is a portion of your hard drive that acts as an extension of your physical RAM. Increasing the virtual memory allocation can help alleviate high RAM usage in Diablo 4. To adjust virtual memory on Windows, right-click on the Start button, select System, go to the Advanced system settings, click on the Performance settings, navigate to the Advanced tab, and click on the Change button under Virtual memory. From there, you can increase the initial and maximum size of the virtual memory.

If you're still experiencing persistent high RAM usage in Diablo 4 after trying the above solutions, it might be time to consider upgrading your system hardware. Adding more RAM can provide your PC with additional resources to handle the demands of the game. Additionally, upgrading other components such as your processor or graphics card can also improve overall performance and reduce RAM usage in Diablo 4. Consult with a knowledgeable professional to determine the best hardware upgrades for your specific system.
