Diablo 4 Memory Leak Issue on Windows: 13 Ways to Fix it

Memory leaks in Diablo 4 can be caused by a variety of issues. The game is still in development, so issues like this are to be expected. The main cause of the memory leak appears to be the texture quality settings in Diablo 4. We recommend you to start with the first fix mentioned below and then go through the list until you manage to resolve the issue. let's start.

Method 1: Set Texture Quality to Medium or Low

"High" texture quality seems to be the main cause of memory leaks in Diablo 4. This appears to be an unexpected bug, as users with high-end GPUs and workstations have also reported this as a potential fix. Go to your Diablo 4 settings and set the texture quality to Medium or Low. Once done, restart your PC and try launching Diablo 4 again. If the memory leak is caused by high-quality textures, the problem should be solved for you by now.

Method Two: Reduce Draw Distance

Draw distance seems to be another cause of memory leaks in Diablo 4. Draw distance determines the distance at which elements are rendered in the game, including NPCs, environments, structures, etc. A higher draw distance renders distant elements in the game, providing better visual quality compared to the standard draw distance. However, this uses a lot of memory and may cause memory leaks when playing Diablo 4. Go to Diablo 4 and click Options >Graphics >View Distance. Reduce the View distance to an acceptable value and restart the game when done. If the higher draw distance is the cause of the memory leak, this should have been fixed for you by now.

Method 3: Set the game to be windowed (full screen)

If you are still facing memory leaks and crashes, we now recommend that you set the game to Window(Fullscreen)Mode. Exiting full-screen mode while playing Diablo 4 is a known cause of Windows memory leaks. Many of us like to play games with other media or apps open in the background, whether it’s Spotify, Discord or OBS. This has led to us all using the Alt Tab keyboard shortcut to switch between applications. Unfortunately, this is a known cause of memory leaks. If you can, we recommend that you don't use this keyboard shortcut to switch apps just yet. Additionally, you should set the display mode to Windowed (Fullscreen). Go to Diablo 4 and click Options > Graphics > Screen, then click to display the drop-down menu. Select Windowed (Full Screen) and restart the game. If they are caused by the game's full-screen mode, you should no longer face memory leaks.

Method Four: Turn off perimeter lighting

Peripheral lighting is another known cause of memory leaks in Diablo 4. If you are still facing this issue, we recommend turning off peripheral lighting in the game. This visual quality setting helps illuminate your peripherals along with the game's ambient lighting, depending on your current location. This fairly new setup can also cause memory leaks. Go to Diablo 4 and click Options > Graphics > Display > Ambient Lighting. Click and uncheck the box for this option and restart the game. If the reason for this issue on your PC is peripheral lighting, you should no longer face memory leak issues. Method Five: Turn off Ray Tracing

Ray tracing is another known cause of memory leaks in Diablo 4. If you are still facing this issue then we recommend you to turn off ray tracing in Diablo 4 settings. Although very visually pleasing, ray tracing can take a toll on your resources, especially memory. This can lead to memory leaks and other bugs that can cause Diablo 4 to crash. After turning off ray tracing, restart the game and try playing again. If ray tracing is the cause of memory leaks on your PC, that issue should be fixed for you by now.

Method 6: Limit the frame rate to match your monitor

Frame rate is another cause of memory leaks in Diablo 4. If you don't set a frame limit, the game seems to render a lot of frames. This can lead to excessive memory usage, which can lead to Windows system crashes. We now recommend that you limit your frame rate to match your monitor's refresh rate. Go to Options > Graphics > Performance. Now dial in your Maximum Foreground FPS and Background FPS values ​​to match your monitor. Once done, restart the game. If frame rate is the cause of memory leaks on your PC, this issue should be fixed for you by now.

Method 7: Reset UI and Add-ons

If you are still facing memory leak issues, we now recommend resetting the UI and any add-ons that may be activated for Diablo 4. This is another known cause of memory leaks in Diablo 4. Open the Blizzard launcher and click OptionsDiablo 4. Click Show in Explorer to open the location where Diablo 4 is installed. Rename the following folders mentioned below. You can add OLD at the end of each folder name to rename them so they won't be recognized by the game.

• Interface
• Cache
• WTF

Once completed, launch the game again to build the new folder. If the UI and add-ons are causing memory leaks, that issue should be fixed for you by now.

Method 8: Using ISLC

ISLC is a nifty utility that helps clear the standby list in memory when needed. This can help mitigate memory leaks in Diablo 4. This is not a permanent fix, but a temporary fix to help you play the game until the developers fix this issue with a future update. Use the link below to download ISLC and extract the archive. After extraction, start the application and check the Start ISLC minimized and auto-Start monitoring checkbox. After completion, also select the "Start ISLC when user logs in" checkbox. This will allow the application to launch when your PC boots up. Once completed, click Start. ISLC will now begin monitoring your waitlist. You can now minimize ISLC and play Diablo 4 as you would. If the problem is caused by your standby list becoming full, you should no longer face a memory leak crash.

Method 9: Close programs running in the background

As mentioned above, background applications are known to cause memory leaks in Diablo 4. We now recommend that you close any background applications that may be open on your PC. This includes monitoring software, other game launchers, Discord, OBS, Twitch, and more. This can be a little frustrating, but if you're used to multitasking when playing Diablo 4, your only option is to play the game without any apps open. This will help temporarily fix the memory leak until Blizzard releases a fix in a future update.
