Awesome! Will this be supported on multiplayer?

Isn't rain synced?

You could try installing a virtual machine running Windows. Peformance might be poor though.

Great update!

Already tried reinstalling the multiplayer mod?

I'd verify the integrity of the game cache first. To do so, right click Euro Truck Simulator 2 in your Steam library and select properties, go to the local files tab and click verfiy integrity of game cache. Wait for it to finish and let it download missing files (if there are any). Then you can try launching the game again.

Are you connected to the internet via wifi or via ethernet? Have you checked your ping? Since you see everyone lagging, but for them you're the only one lagging I'd say it has something to do with your connection to the servers.
