Manually Setting the Paging File (Virtual Memory)

When your system runs out of physical RAM, it uses a reserved portion of the disk called the paging file (or virtual memory). By default, Windows manages this size dynamically — but on a system dedicated to gaming with GameLoop, a poorly configured or undersized paging file can lead to:

• Application crashes

• FPS dips during memory spikes

• General system instability

In this guide, we’ll manually set a fixed paging file size to ensure consistent performance and prevent sudden slowdowns.

Step-by-Step: Set Paging File Manually in Windows 10

📍 Step 1: Open Virtual Memory Settings

• Press Win + R, type sysdm.cpl, and hit Enter

• Go to the Advanced tab

• Under Performance, click Settings

📍 Step 2: Disable Automatic Management

• In the Performance Options window, go to the Advanced tab

• Click Change under Virtual Memory

• Uncheck: Automatically manage paging file size for all drives

📍 Step 3: Select the System Drive

• Select the drive where Windows is installed (typically C:)

📍 Step 4: Set a Custom Size

Use a fixed size to avoid runtime resizing delays:

Enter these numbers in Initial size (MB) and Maximum size (MB) fields
Click Set → OK

📍 Step 5: Restart Your Computer

Changes will take effect after reboot.

Why This Helps

Manually allocating virtual memory prevents Windows from resizing the paging file on the fly, which can lead to input lag, stuttering, or freezing — especially while running GameLoop with limited RAM.

⚠️ Best Practices

• Don’t disable the paging file entirely, even with large RAM

• Always use fixed size — dynamic sizing adds unnecessary overhead

• Place it on the fastest drive available (preferably SSD)
