You can play Call of Duty: Modern Warfare on low RAM by reducing system load, lowering in-game graphics, and optimizing background processes. Follow these steps in order to get the best results.

How to Play Call of Duty on Low RAM?

Step 1: Close Background Applications

Low RAM systems struggle when too many programs run together.

Follow these steps:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click the Processes tab.
3. Right-click unused apps such as browsers, launchers, or media players.
4. Select End Task for each unnecessary program.

Closing background tasks can free 500 MB to 2 GB RAM, depending on active applications.

Step 2: Lower In-Game Graphics Settings

Graphics settings use large amounts of RAM and VRAM.

Open the graphics settings inside Call of Duty: Modern Warfare and apply these values:

• Texture Resolution: Low
• Texture Filter Anisotropic: Low
• Particle Quality: Low
• Shadow Map Resolution: Low
• Cache Spot Shadows: Disabled
• Cache Sun Shadows: Disabled
• Anti-Aliasing: Off
• Motion Blur: Disabled
• Film Grain: 0.00

Low graphics reduce memory usage and improve frame stability on systems with 4 GB to 8 GB RAM.

Step 3: Set Game Priority to High

Changing priority improves CPU allocation.

Steps:

1. Launch the game.
2. Open Task Manager again.
3. Find ModernWarfare.exe under Processes.
4. Right-click the process.
5. Select Set Priority → High.

This change reduces stuttering and improves responsiveness.

Step 4: Increase Virtual Memory (Paging File)

Virtual memory allows Windows to use storage as extra RAM.

Use these steps in Windows 10 or Windows 11:

1. Open Control Panel.
2. Select System → Advanced System Settings.
3. Click Performance → Settings.
4. Open Advanced → Virtual Memory.
5. Uncheck Automatically Manage.
6. Set Initial Size to 4096 MB.
7. Set Maximum Size to 8192 MB or higher.
8. Restart the system.

Virtual memory increases stability on systems with limited RAM.

Step 5: Use Fullscreen Mode

Fullscreen mode reduces resource overhead.

Set:

• Display Mode: Fullscreen
• Render Resolution: 80 percent to 100 percent

Windowed modes consume additional RAM and CPU resources.

Step 6: Disable Startup Programs

Startup programs use RAM immediately after boot.

Steps:

1. Open Task Manager.
2. Click the Startup tab.
3. Disable programs such as launchers and auto-updaters.
4. Restart the computer.

Disabling startup items reduces idle memory consumption.

Optimize System Performance for Low RAM Gaming

System optimization improves stability and frame delivery. These methods support smooth gameplay even with limited memory.

Update Graphics Drivers

Updated drivers improve compatibility and memory handling.

Use official tools such as:

• NVIDIA GeForce Experience
• AMD Radeon Software

Driver updates often improve performance by 5 percent to 15 percent.

Use Game Mode in Windows

Game Mode prioritizes resources for gaming tasks.

Enable it:

1. Open Settings.
2. Select Gaming.
3. Turn on Game Mode.

Game Mode improves frame consistency and reduces interruptions.

Defragment HDD or Optimize SSD

Storage performance affects loading speed.

Use:

• Defragment and Optimize Drives tool in Windows.

Expected benefits:

• Faster level loading
• Reduced freezing during gameplay

This step is important when using traditional hard drives.

Adjust Game Configuration Files for Better Performance

Manual file changes can further reduce RAM usage.

Edit Config File Settings

Locate the configuration folder:

Documents → Call of Duty Modern Warfare → Players

Open the adv_options.ini file.

Change these values:

• VideoMemoryScale = 0.55 to 0.70
• RendererWorkerCount = 2 to 4

Lower memory scale reduces VRAM pressure.

Renderer worker settings improve CPU performance.

Disable Background Overlays

Game overlays consume memory and CPU resources.

Disable overlays in:

• Discord
• Steam
• Xbox Game Bar

Overlay removal improves stability during gameplay.

Hardware Adjustments That Improve Low RAM Gaming

Hardware improvements provide long-term solutions.

Upgrade RAM Capacity

RAM upgrades deliver the biggest performance gain.

Recommended RAM sizes:

• Minimum playable: 8 GB RAM
• Smooth performance: 12 GB to 16 GB RAM

Using dual-channel memory improves speed by 10 percent to 25 percent.

Install Game on SSD

Solid State Drives load assets faster.

Benefits include:

• Faster loading times
• Reduced stuttering
• Improved texture streaming

Use SSD models from reliable brands such as:

• Samsung
• Western Digital
• Crucial

SSDs reduce loading delays significantly compared to HDD storage.

Recommended Minimum Settings for Low RAM Systems

Balanced settings help maintain stable frame rates.

For 4 GB RAM Systems

These systems are highly limited.

Suggested settings:

• Resolution: 1280 × 720
• Texture Quality: Low
• Anti-Aliasing: Disabled
• Render Resolution: 70 percent
• Background Apps: Closed

Expected performance:

• 20 to 35 FPS average range

For 8 GB RAM Systems

These systems perform better.

Suggested settings:

• Resolution: 1600 × 900 or 1920 × 1080
• Texture Quality: Low to Medium
• Shadow Quality: Low
• Anti-Aliasing: SMAA 1X

Expected performance:

• 40 to 60 FPS average range

Additional Tips to Reduce Lag and Memory Usage

Small changes produce measurable improvements.

Use Low Resolution Textures

Lower resolution textures require less memory.

Benefits:

• Reduced stuttering
• Faster texture loading
• Stable frame pacing

Texture reduction significantly lowers RAM pressure.

Keep System Temperature Low

High temperature reduces performance.

Use:

• Cooling fans
• Laptop cooling pads
• Dust cleaning tools

Temperature control maintains stable clock speeds.

Restart System Before Gaming

System restart clears memory cache.

Expected result:

• Frees 300 MB to 1 GB RAM
• Improves initial performance

This method is simple and effective.
