For Users with 256 MB RAM or more this tweak will boost their Windows- and Game-Performance.
What it does: It tells Windows not to use any Swap File until there is really no more free RAM left.
Open the System Configuration Utility by typing msconfig.exe in the RUN command. There in your System.ini you have to add “ConservativeSwapfileUsage=1” under the 386enh section.
Restart your Windows and enjoy better Game performance
This tip does absolutely nothing on Windows 2000 and later. The system.ini file is strictly for compatibility with old 16 bit applications and Windows ignores it.
