CPU performance
One of the biggest steps in developing an entire new engine was to design a true multithread-capable engine. X Rebirth will make full use of latest generation CPUs by spreading the work in many parallel running threads.

What engine and API do we use?
X Rebirth will run on DX9 API as long as all the features that we need from the API are possible with it. That does not mean we may not at some point also support DX11, but for now we do not see a need. Our engine is quite different from all the big established names, because it is designed specifically for a space game. We had a look at engines like Unreal or the CryEngine, but because we wanted to have cutting edge space graphics, an area very different from what these engines are specialized in, we had to develop our own engine.

Will X Rebirth support modding?
We definitely aim to support modding again. Since this is an entirely new engine, we can not provide any documentation and API support before the game comes out, but we hope to provide this soon after the release.

How is scripting going to be supported?
The new engine supports a scripting system very similar to the MD language used in Terran Conflict. It will be strongly modified for the new engine, but if you understand MD already, chances are that you will find it relatively easy to write missions for the new game. XML based languages are also used in many other areas of designing a game with the new Rebirth engine.
