Instances & accounts

Your main and your alts. At the same time.

Stay logged into every account at once and switch in a click. Each instance is a sealed environment, its own version, settings, cache, and mods, so nothing ever leaks between them.

Run several at once — your main and your alts playing simultaneously.
Live presence — see who's in-game, idle, or trading, at a glance.

Performance & tuning

Goodbye, 60 FPS.

Flip the cap off and watch your frame rate fly. Fine-tune everything with a FastFlags editor, and pin the build that works when an update breaks your game.

Uncap your FPS — go from a tragic 60 to unlimited in one toggle.
Version pinning & mods — reversible, and never touching your install.
