RamTrimMod

Description

RamTrimMod is a native C++ UE4SS mod that periodically trims the game process's working set, forcing Windows to release unused physical memory back to the system. This can meaningfully reduce the RAM footprint shown in Task Manager during long play sessions, without affecting game state, save data, or performance.

Features

Automatic trim every 1 minute
Manual trim on demand with the F10 hotkey
Logs before/after memory size to the UE4SS console for dev's. [2026-07-16 16:07:20.8901275] RamTrimMod trimmed process identifier 5280: 2599.34 MB -> 399.16 MB
No impact on save files, game logic, or Blueprint state

Installation

Make sure UE4SS is installed for your game.
Copy the RamTrimMod folder into:
