Game Patches & Disk Space
PGN installs small patches into your game folders to enable online multiplayer.
These patches may increase your game's disk usage:
| Railroad Tycoon 3 |
~1 MB (proxy DLL + config) |
| Age of Empires II |
~50-200 MB (proxy DLL + community patches + mods) |
| Hearts of Iron IV |
~200 MB - 1.5 GB per version (version deltas for rollback support) |
Patches are installed inside each game's folder and do not modify the original game files.
You can remove them at any time from the PGN Client settings.
