Gameburrow's OMSI 2 settings
Here are my settings. I'd say these are the maximum you can have in OMSI engine, no matter how high end your computer is.
If it's still lagging, you need to reduce:
- scheduled AI count (this hits performance the most)
- unscheduled AI count even more
- Max sound count is also interestingly something that hits performance quite a lot.
OMSI depends mostly on CPU, RAM and Disk speeds. CPU and RAM are running on 32bit limits thus it can't use more than 4GB of memory.
