How to Set Up and Optimize GOG Galaxy for Smooth Gaming

GOG Galaxy: The Ultimate Guide to Managing Your PC Game LibraryGOG Galaxy is a PC gaming client built by GOG (formerly Good Old Games) that aims to give players a single, tidy place to store, launch, and maintain their games — whether purchased from GOG.com, other storefronts, or installed locally. Unlike many modern launchers, GOG Galaxy emphasizes ownership, optional DRM-free installs, and user control while also offering convenient features like cloud saves, automatic updates, and cross-platform friend lists. This guide covers installation, setup, library organization, integrations with other launchers, advanced features, troubleshooting, and tips to keep your collection neat and accessible.

What GOG Galaxy does (quick overview)

Single unified library: combines GOG purchases with games from multiple platforms (Steam, Epic, Origin, Uplay/Ubisoft Connect, Xbox, PlayStation via backward sync tools) and manually added non-client games.
DRM-free focus: GOG-owned titles are DRM-free, meaning you can install and play without a persistent online check.
Optional cloud features: cloud saves, achievements, and automatic updates are available but optional per game.
Friends & social: cross-platform friend lists, chat, and activity feeds.
Rollback & patching: downloadable older versions/patches for certain titles and an option to disable automatic updates.

Getting started

Installing GOG Galaxy

Download the installer from GOG.com.
Run the installer and follow prompts (select install location, agree to optional features).
Sign in with your GOG account or create one. Signing in enables cloud saves, sync, and storefront features, but you can still use the client offline for local games.

Initial configuration

Open Settings → Interface: choose theme, language, and library layout (grid/list).
Settings → Download & Installation: set default install paths, concurrent download limits, and whether updates are automatic.
Settings → Cloud saves & Sync: toggle cloud saves and choose per-game behavior.
Settings → Integrations: connect other launcher accounts (Steam, Epic, Xbox, Ubisoft) to import games.

Organizing your library

GOG Galaxy’s strength is turning a cluttered collection into a searchable, filterable catalog.

Library views and filters

Grid vs. List view: grid shows large cover art; list shows compact details (last played, size, version).
Filters: installed, not installed, favorites, recently played, completionist tags (achievements), and custom tags.
Sorting: by name, last played, added date, developer, or size.

Using tags and favorites

Add custom tags (e.g., “RPGs”, “Mods installed”, “Multiplayer”) to group games across storefronts.
Star games as Favorites to pin them to the top of your library for quick access.

Collections & custom shelves

Create Collections (custom shelves) for series, genres, or moods (e.g., “Co-op Night”, “Retro Classics”, “Currently Playing”) and add games from any source. Collections are great for planning playthroughs or grouping cross-storefront purchases.

Importing games from other launchers

GOG Galaxy can scan and import games from multiple platforms so your library becomes truly unified.

Supported integrations

Steam, Epic Games Store, Ubisoft Connect, Origin/EA App, Xbox, PlayStation (limited), and more via available plugins. Integration lets Galaxy detect installed games, show playtime, and launch them directly.
For services without native integration or for DRM-free installers, use “Add a game” → “Add a non-GOG game” and point to the game’s executable.

Linking accounts

Go to Settings → Integrations and sign in to each platform. Grant the requested permissions to allow GOG Galaxy to read your owned games and installed status. After linking, run a library sync to populate entries.

Handling conflicts and duplicates

If the same title appears from multiple sources, Galaxy shows multiple entries; you can hide duplicates or add the preferred version to a Collection. For some multi-source titles, Galaxy will group them under a single unified card with launch options.

Installation, updates, and rollback

Installing games

Choose an install location (per-game or default path). GOG Galaxy supports multiple drives and custom folders.
For GOG purchases, installers are DRM-free but Galaxy offers one-click installs and optional background patching.

Updates and rollback

Automatic updates can be toggled globally or per-game. For older games, automatic updates can sometimes break mods or compatibility—disable auto-updates for those titles.
Where available, use Rollback to revert to prior game versions (helpful if a recent patch introduced issues). Not every game supports rollback.

Backup and restores

Manual backups: copy the installed game folder or use GOG’s downloadable installers for offline recovery.
Cloud saves: ensure they are enabled per game if you want save synchronization across machines.

Mods, overlays, and third-party tools

Mod management

GOG Galaxy itself does not centrally manage mods, but you can:
- Add a modded executable as a “non-GOG game” entry.
- Keep a separate folder for modded installs and add it to the library.
- Use specialized mod managers (Vortex, Mod Organizer 2) alongside Galaxy; set them as the launcher for modded games.

Overlays and performance tools

Galaxy’s in-client overlay is minimal. For features like FPS counters, video capture, or low-level performance tweaking, use third-party tools (MSI Afterburner, OBS, Nvidia/AMD overlays). Launch those alongside Galaxy-launched games.

Cross-device play and cloud saves

Cloud saves are supported for many GOG titles and some integrated games. Enable them per game in the game’s settings within Galaxy.
For games without cloud save support, use manual save backups or third-party cloud sync (Dropbox, OneDrive) by redirecting save folders.

Friends, cross-play, achievements

Add friends by GOG username — cross-platform visibility is limited by what integrations reveal.
Achievements: GOG Galaxy supports achievements for GOG titles and can display third-party achievements where supported. These sync across devices when cloud features are enabled.

Privacy and ownership model

GOG’s philosophy emphasizes user ownership: GOG titles are DRM-free, meaning you can run installed copies without always being online. Galaxy adds convenience features but does not force DRM.
You can disable automatic sync, cloud saves, or even use the installers without the client if you prefer full offline control.

Advanced tips and power-user tricks

Use multiple install drives: set per-game install paths if you have SSDs for performance-critical titles and HDDs for bulk storage.
Disable auto-updates for modded/old games to avoid breaking setups.
Use Collections to create a “Wishlist to Play” shelf and move games there after purchase until you start them.
For multi-storefront management, periodically re-run integrations to detect new purchases.
If you want to keep a pristine offline copy, download GOG installers (from the site) and archive them externally.

Troubleshooting common issues

Game won’t launch: try running the executable as admin, check antivirus quarantines, or launch directly from the game folder. If integrated from another launcher, ensure that launcher is installed and logged in if required.
Cloud saves not syncing: check Settings → Cloud saves is enabled; verify you’re signed in and that the game supports cloud saves. Conflicts may create .local and .remote save files — back up both before resolving.
Integration not detecting games: ensure the other launcher is installed in its default location or add the library path manually in Integrations. Relaunch Galaxy after linking accounts.
Slow downloads: change the concurrent download limit or switch download servers in Settings → Downloads.

When to use GOG Galaxy vs. vanilla installers or other launchers

Use GOG Galaxy when you want a unified, convenient, and user-friendly library with optional cloud features and updates.
Use standalone installers when you need absolute offline control, wish to keep a completely separate modded install, or want to avoid a client entirely.
Keep other launchers if specific titles require them (some multiplayer or anti-cheat systems need the original storefront client).

Summary (what to remember)

Unified library, cross-store integration, and optional cloud features are the core strengths.
DRM-free ownership for GOG-bought titles remains a key differentiator.
Collections, tags, and integrations make it practical to manage large, multi-source libraries.
Use rollback, disable auto-updates for fragile installs, and back up save files for peace of mind.
