Why OMSI 2 runs out of memory, and what 64-bit changes
Why big maps and detailed buses can crash OMSI 2, what the 4 GB limit of a 32-bit program really is, and what running as a 64-bit application changes in OMX.
How OMSI 2 works, and how OMX reproduces it
Reimplementing OMSI 2 accurately means understanding exactly how the original behaves. These articles document that work: the internals of OMSI 2, the details existing content depends on, and how OMX approaches them.
