OMX FAQ
Short, direct answers about OMX. Anything not covered here is covered in more depth on the What is OMX page.
About OMX
What is OMX?
OMX is a new implementation of OMSI 2, the bus simulator, written from scratch as a modern 64-bit application. It runs existing OMSI 2 content — buses, maps, scenery and add-ons — and aims to reproduce the behaviour of the original simulation as accurately as possible. Read the full explanation.
Is OMX a mod for OMSI 2?
No. OMX does not modify or patch OMSI 2. It is a separate program that implements the simulation itself, and it reads the content from your existing OMSI 2 installation.
Is OMX related to openOMSI (Open OMSI)?
No. OMX is not related to openOMSI. They are separate projects that both reimplement OMSI 2, with different approaches to source code, platforms and availability. See how they compare.
Is OMX affiliated with MR Software or Aerosoft?
No. OMX is an independent project and is not affiliated with MR Software or Aerosoft. OMSI and OMSI 2 are trademarks of their respective owners.
Is OMX a graphical remaster of OMSI 2?
No. OMX runs the models and textures your content already has. Its focus is compatibility, accuracy and modern performance, not changing how OMSI content looks.
Why reimplement OMSI 2 instead of improving the original?
OMSI 2 is a 32-bit application, and many of its limits are part of the original engine itself. A new implementation can remove those limits while keeping the large library of community-made buses, maps and scenery usable, and can keep being developed.
Is OMX open source?
No. OMX is closed source.
Requirements & compatibility
Do I need OMSI 2 to use OMX?
Yes. OMX requires an installation of OMSI 2. OMX does not include any OMSI 2 content; it runs the content from your own installation.
Will my existing buses, maps and add-ons work?
They should. OMX is meant to run anything that runs in OMSI 2: buses, maps, scenery objects, scripts, textures, sounds, timetables, AI traffic and passengers. It is still in development, so expect gaps while they are being filled.
Which operating systems does OMX support?
OMX runs on 64-bit Windows and 64-bit Linux. macOS has not been tested.
Is OMX a 64-bit application?
Yes. OMX is built as a modern 64-bit application, so it is not bound by the memory limits of a 32-bit process like the original OMSI 2.
Availability & pricing
Can I download OMX?
Not yet. OMX is in a closed beta and there is no public download. Selected testers receive a private download link, and OMX then updates itself from within the client. Current availability is kept up to date as that changes.
How do I join the beta?
Beta testers are selected by the OMX developer from the OMX Discord community. There is no application form, and joining the Discord does not guarantee a place.
Will OMX cost anything?
The OMX client is free. Hosted dedicated servers for OMX will be offered separately, as an optional subscription.
What are hosted OMX servers?
OMX will offer hosted dedicated servers as an optional paid subscription, run and managed on your behalf. Plans and pricing have not been announced yet.
When will OMX be released?
No release date has been announced. Development updates are published as work progresses.
Where can I follow OMX development?
On the OMX Discord, and through the development updates published on this site.
