Troubleshooting common issues

[emoose]

If you run into any issues with Tweaks, you might find a solution below - if your problem isn't covered here, please feel free to create an issue report (or ask about it on the OR2006Tweaks discord)

• My controller isn't detected by the game.

The latest Tweaks releases replaced the games controller code with SDL3, which should support most common controllers & possibly wheels too - SDL3 has many ways of talking to these devices though, and may pick one that doesn't work properly with your system.

The InputBackend setting in the overlays Controls section lets you switch which backend is used, you can pick between 4 options there, hopefully one of them should get it working.

If you still have issues with your controller feel free to create an issue report.

• The game has random lags/stutters during gameplay.

Check if you have VibrationMode enabled, on some Bluetooth controllers this can cause lag in newer Windows releases, switching the InputBackend may help solve the hitching, but if not the only other solutions are either connecting with a wire, or disabling vibration entirely (Xbox wireless adapter doesn't seem affected)

If vibration isn't the cause, you could try reducing the ReflectionResolution setting, some have mentioned that having it too high had caused framerate issues in the past.

• The game has very long load times.

This can be caused by either having too many texture replacements in use, or an external tool (or GPU driver setting) may be applying a framelimit to the game - Tweaks itself handles framelimiting pretty accurately, so external tools shouldn't be required.

• The skybox in the game looks buggy / doesn't render properly.

This could be caused by TransparencySupersampling setting, some have reported skybox issues with certain cards with that enabled.

• The game crashes on launch, or when loading in.

Make sure you have a clean copy of the game files, some versions available online may have corrupt game data.

Games install location can cause issues if installed somewhere that needs special permissions (such as Program Files folder), try copying the game files somewhere that doesn't need those permissions (eg. a folder on desktop)

Check if any external tools are running that may be trying to hook into the game too.

You can also try clean-installing your graphics card driver (during driver install/update there should be an option to clean-install it), this may clear out any driver settings that might be interfering.

• I'm unable to host online, the game mentions not being accessible.

To host games you need the 41455/41456/41457 UDP ports forwarded to the internet, Tweaks tries to forward these automatically with compatible routers, but some may have issues with it.

There may be a guide available for forwarding on your router, try searching online for "[router model] port forwarding".

Some ISPs may not allow port forwarding, or use a CGNAT setup that make it impossible, unfortunately you might not be able to host games with those (could always drop into the Discord and ask if someone else wants to host though!)

(It may be worth checking Windows Firewall settings for the game too, it's possible the game was blocked by mistake.)

• When certain people are in a lobby, I'm unable to join.

The games netcode requires everyone in a lobby to connect to each other, if you're unable to join lobbies only when certain people are present, there may be some connection issue between you and them.

Joining games usually doesn't require port forwarding to work, but forwarding the ports mentioned above may be able to help it (if you know who you're having issues with, it could be worth contacting them too)

It might be possible to adjust the netcode in future - things are in the works...

• During an online game the stage disappeared, and I was driving in the void?

Desyncs are known to happen with the games current netcode sadly. This likely happens more often if other players are located very far from you, with high ping rates.
