Memory leaks are quite common in PC games such as Kingdom Come Deliverance 2. This can significantly impact performance, stability, and user experience. If you're seeking solutions for Kingdom Come Deliverance 2 memory leaks, this guide is ideal for you.

Kingdom Come Deliverance 2 Memory Leak

As one of the most immersive RPGs, Kingdom Come Deliverance 2 enables you to role-play in a genuinely authentic setting that reacts convincingly to your actions. Similar to many new games, this title also experiences some glitches and bugs. Kingdom Come Deliverance 2 memory leak is among the most bothersome issues you might face.

Proper memory allocation and deallocation are crucial for smooth and consistent program execution. A memory leak in Kingdom Come Deliverance 2 suggests that the game can allocate memory but fails to free it when it's no longer needed. Typical signs of this problem include out-of-memory situations, shutdowns, lags, crashes, and visual glitches.

Fix 1: Remove RenoDX HDR Mod

If you come across Kingdom Come Deliverance 2 running out of video memory on an NVIDIA GeForce RTX 4090, the RenoDX HDR mod might be the culprit. Removing this mod could resolve the issue.

Fix 2: Enable Sysmem Fallback Policy for the Game

The NVIDIA Control Panel provides an option named Prefer Sysmem Fallback that permits programs to use RAM as an overflow for VRAM when the GPU runs out of memory. Activating this option can prevent Kingdom Come Deliverance 2 memory leaks or crashes. Here's how to do it:

Step 1. Launch NVIDIA Control Panel.

Step 2. Navigate to Manage 3D Settings > Program Settings > select Kingdom Come Deliverance 2.

Step 3. Scroll down to find CUDA-Sysmem Fallback Policy and choose Prefer Sysmem Fallback.

Step 4. Apply the changes.

Fix 3: Adjust Shader Cache Size

Reports indicate that some NVIDIA drivers may reset the shader cache size to 0, causing Kingdom Come Deliverance 2 to consume excessive memory. Hence, increasing the shader cache might solve the problem. To achieve this:

Step 1. Open NVIDIA Control Panel.

Step 2. In the left pane, select Manage 3D Settings.

Step 3. In the Global settings section, select Shader cache size and set it to driver default or pick a high value.

Step 4. Save the changes and relaunch the game to check if the Kingdom Come Deliverance 2 memory leak persists.

Fix 4: Free up Memory with MiniTool System Booster

When it comes to memory issues like Kingdom Come Deliverance 2 memory leaks, a PC optimization tool called MiniTool System Booster proves useful. Available on Windows systems, this tool is designed to help you extract maximum performance by cleaning up your device, speeding up applications, defragmenting hard drives, etc.

The ActiveCare feature can monitor your device for issues and automatically fix them, including memory-related problems. Here's how to release more memory with this tool:

Step 1. Launch this freeware.

Step 2. On the Performance Home page, turn on ActiveCare and press RUN SCAN to initiate the process.

Step 3. After scanning, click on FIX ISSUES to resolve all detected issues simultaneously. This process can remove Windows junk files and Internet junk files, address registry issues, discover available memory, and list some potentially unnecessary startup programs.

To create more available memory, you can enable RAMJet in the LiveBoost section and run Process Scanner in the Toolbox section. The former clears old caches when additional RAM is required, and the latter can assist in identifying and terminating unnecessary memory-intensive tasks.

Fix 5: Modify Launch Options

Another method is to launch your Kingdom Come Deliverance 2 in developer mode. This mode helps players detect and potentially address performance bottlenecks by providing access to detailed statistics and settings. Additionally, the user.cfg file enhances system and video memory allocations, which might also enhance game performance issues like Kingdom Come Deliverance 2 memory leaks. To proceed:

Step 1. Download the user.cfg file from Nexus Mods.

Step 2. Open File Explorer and navigate to the KCD2 folder:

For Steam:

steam/steamapps/common/KingdomComeDeliverance2

For Epic Games:

Epic Games\Epic Launcher Games\KingdomComeDeliverance2

For GOG or no launcher:

KingdomComeDeliverance2\Bin\Win64MasterMasterSteamPGO

Step 3. Move the user.cfg file into this directory.

Step 4. Change launch options:

On Steam

1. Launch Steam and visit Library.
2. Right-click on Kingdom Come Deliverance 2 and select Properties.
3. In the General tab, enter exec user.cfg -devmode in the Launch Options field.

2. Right-click on your shortcut to select Properties and proceed to the Shortcut tab.
3. At the end of the Target field, add exec user.cfg -devmode.

Step 5. Save all modifications made.

Fix 6: Roll Back Your Graphics Driver

For certain reasons, the latest driver released by Nvidia might conflict with the game, leading to Kingdom Come Deliverance 2 running out of memory. In such cases, rolling back the driver to a previous version is a viable solution. To accomplish this:

Step 1. Type device manager in the Windows search bar and press Enter.

Step 2. Expand the Display adapters category and right-click on your graphics card driver to select Properties.

Step 3. In the Driver tab, you can view the version of your graphics card driver. If you're using Nvidia driver version 572.16, click on Roll Back Driver and wait for it to complete.

Fix 7: Increase Virtual Memory

There's a possibility that the default virtual memory settings don't allocate sufficient space for the game. If this is the case, you can manually increase the virtual memory on your computer:

Step 1. Press Win R to open the Run box.

Step 2. Type sysdm.cpl and press Enter to open System Properties.

Step 3. Go to the Advanced tab and click Settings under Performance.

Step 4. Proceed to another Advanced tab and click on Change.
