Virtual Memory Settings

Windows allows you to configure virtual memory (paging file), which supplements physical RAM with disk space. Increasing the paging file size can help if your system runs out of physical RAM, though it is slower than actual RAM.

To adjust virtual memory:

  • Open **Control Panel** > **System and Security** > **System**.
  • Click **Advanced system settings** > **Performance** > Settings.
  • Under the Advanced tab, click Change in Virtual Memory.
  • Uncheck Automatically manage paging file size, then select Custom size.
  • Set initial and maximum sizes according to your system’s RAM (usually 1.5 to 3 times the installed RAM).

Allocating RAM Using Configuration Files and Command Line Arguments

Some games and engines allow manual RAM allocation through configuration files or command line parameters. This method is common in games that do not provide GUI options for memory management.

Editing Configuration Files

  • Locate the game’s configuration file, often named `config.ini`, `settings.cfg`, or similar.
  • Look for entries related to memory or heap size.
  • Modify values according to desired RAM allocation, typically expressed in megabytes (MB) or gigabytes (GB).

Using Command Line Arguments

When launching the game executable, you can append arguments to control RAM usage. Common parameters include:

Parameter Description Example
`-Xmx` Sets the maximum heap size (Java games) `-Xmx4G` (4 GB)
`-Xms` Sets the initial heap size (Java games) `-Xms2G` (2 GB)
`–memory` Custom argument for specific game engines `–memory=4096`

To apply these:

  • Create a shortcut to the game executable.
  • Right-click the shortcut and select Properties.
  • In the Target field, append the desired arguments after the file path.
  • Click Apply and launch the game via this shortcut.

Recommended RAM Allocation Guidelines for Various Game Types

Proper RAM allocation depends on the game’s technical requirements and your system’s total memory. Below is a guideline table illustrating typical RAM allocations for different game categories:
