Roadworthy fixes how the beta syncs cars, players and items, reduces stutter, and makes 150+ other fixes to the base game. Free. Windows only.
Passengers no longer see the car freeze every few seconds. The driver owns the car, so a short network hitch doesn't hand it to a passenger.
Joining players are placed on loaded ground in a clear spot. Players with different mods can still join. If a join fails, a message says why.
Less stutter when new areas, buildings and roadside stops load. Roads, mirrors, debris and parked cars cost less to run.
Items in the glove box, cab and bed stay put for passengers. Held items no longer disappear, and quitting no longer deletes worn items.
New worlds keep the biome you pick. Mountains are less likely to block roads, buildings spawn on flatter ground, and the ground no longer disappears when you change view distance.
All options are in Settings → Roadworthy: shadow quality, performance preset, car smoothing, faster multiplayer, and a reset button.
Optional changes, most of which can be turned off in the Roadworthy tab:
| Situation | Base game beta | Roadworthy |
|---|---|---|
| Riding as a passenger | Car freezes for up to a second every few seconds | Up to 60 updates a second |
| Other players walking | About 3 updates a second; players skip ahead | 30 updates a second |
| Joining | Can spawn inside a car or wall, or get stuck at the menu | Placed on loaded ground; failures show a reason |
| Players with different mods | Join refused | Allowed; only the game and Roadworthy versions must match |
| Trailers | Can't be hitched | Hitch and sync for everyone |
| A player leaves | Remaining players freeze | Session continues |
| New areas loading | Stutters on buildings and roadside stops | Loads without the freeze |
The installer finds your Steam copy of the game, builds the patch against your own game files, and checks it before replacing anything.
The game must be on beta build listed in the release notes.

Yes, on the Steam beta branch. Roadworthy fixes most of its syncing problems: passengers get car updates up to 60 times a second instead of about 5, and other players update 30 times a second instead of about 3.
The Steam beta build named in the latest release notes, on Windows 10 or 11. The installer checks this for you.
No. Only the game version and the Roadworthy version have to match. Other mods, extra files and custom maps can differ. If versions don't match, a message shows which version each player has.
No. The installer doesn't modify saves, and the game keeps a .bak backup when it saves.
Run the installer again and click Restore original, or run Restore Original.cmd. This puts the original game files back.
