It took longer than anticipated but we were finally able to prepare maps and schedules for the Chicago DLC. This DLC was not easy. It is not optimized for modern equipment.
There are issues with running the Chicago DLC. The DLC is capped at 2GB, but it needs a minimum of 4MB to run somewhat smoothly. Based on the official OMSI2 Forums, someone was able to create a patch to increase the cap to 4GB. This helps with smoother gameplay. We have tried it ourselves and the gameplay was a lot smoother. You can find the patch on: https://ntcore.com/?page_id=371.
As for the schedules, we wanted to created a schedule similar to the one that was created by the Chicago Regional Transit but they don't list out the stops as the BVG does for the original game. We created a schedule that reflects what the Chicago Regional Transit schedules look like. We also create schedules that list out the actual bus stops like BVG does. You may chose what you prefer.
We are going to work on the next DLC: Three Generations. We're going to prepare the manuals, schedules, maps and bus information. It'll take some time but we're going to be more thorough in covering the DLCs moving forward.
