In anticipation of the June 18 launch of the final DLC for TSW1, my game is in the process of being updated with 4.8 GB of data.
I have been able to watch some files being passed around inside the Steam/steamapps/downloading folder and the binary patching going on.
"Today we are bringing an update to Train Sim World 2020, this adds support for the upcoming BR Class 20 Loco Add-On, as well as an additional fix to an existing add-on. Please find the full update log below:
- Adjustments to the BR Class 47 simulation model, featured in Northern Trans-Pennine, to address instances where the loco could become severely underpowered. "
That's all folks, enjoy before the whole game will be 'preserved' in its present state.
