Below you find answers to common questions about the X Rebirth Virtual Reality Edition.

0. Technical problems / Game does not start?

If the game does not start, crashes or stops before even getting into the first 3D scene there is a good chance that you have problems with your 3D driver. Our game requires a Vulkan compatible driver. Always install the latest driver and if problems persist do a clean install (user defined install and delete all settings!

Windows 7 or 8.1 installation
If you are trying to run the game on Windows 7 or 8.1 and run into a crash right before starting the game, you may try to install the Microsoft VS Redistributable package of 2017 from here.

Computer with multiple graphic cards
Another common issue currently is for machines with multiple graphic adapters. Unfortunately our Vulkan engine might be trying to open from the wrong graphic card. To fix this you can temporarily disable a graphic card in your device manager without physically taking the card out of your machine.

NVidia Option: Optimize for compute performance
The Nvidia graphic driver has a setting which should be off by default to optimize performance for computing (as opposed to graphics). This was reported to cause problems with our game. Try turning it off. This is an explanation of the setting:
[1]Nvidia information about compute feature.

GPU below specs
While the Vive (Open VR) version should even run on graphic cards that are slightly below specs (e.g NVidia 7 series), The Oculus build does currently not run on these machines and quits with an error code. Please check the minimum hardware requirements!

VR Controller not shown
VR controller have to be turned on before gamestart. Please restart the game to get VR controller to fully work.

1. When will XR VR be released?

We have now entered the Early Access phase on Steam as well as in the Oculus store. The game will be properly released on both platforms as soon as we end the Early Access phase. We expect Early Access to take between one and three months.

2. On which platforms will XR VR be released?

The XR VR Edition will only be released on Steam and in the Oculus store.

3. Which VR headsets and controllers are supported?

The Steam version of the XR VR Edition supports the HTC Vive (headset and controllers) through OpenVR.
The Oculus store version runs on Oculus Rift and supports the Oculus Touch through the Oculus API.

We are now also providing an Oculus build on Steam for customers to choose from. This build does however require the Oculus store to be running and logged in in order to correctly show the Oculus Touch Avatar (your hands!).

The Open VR version, which is the default on Steam does also run with the Oculus headset, but does not support the Oculus Touch controler.

Both versions of the game can of course also be controlled with joysticks or gamepads OR with a mixture of joystick and VR controller.

In short:

X Rebirth VR Edition purchased on Steam:
  • Vive headset: supported
  • Vive controllers: supported
  • Oculus Rift headset: supported
  • Oculus Touch controllers: supported*

X Rebirth VR Edition purchased on the Oculus Store:
  • Vive headset: not supported
  • Vive controllers: not supported
  • Oculus Rift headset: supported
  • Oculus Touch controllers: supported

We do not officially support other VR headsets (e.g. OSVR) at this point, however the Steam version is using OpenVR and should be compatible with systems that support this as well. Any feedback is very welcome.

* With version 4.20 Hotfix 1 native Oculus Support was added to the Steam version now. Please note that this requires Windows 8 or higher.

4. What are the System requirements?

    OS: Windows 10 (64-bit), Windows 8 (64-bit), Windows 7 SP1 (64-bit)*
    Processor: Intel i5-4590 or AMD equivalent
    Memory: 8 GB RAM
    Graphics: Nvidia GTX 970 or AMD equivalent
    Storage: 8 GB available space
    VR systems supported: Oculus Rift or HTC Vive

    OS: Windows 10 (64-bit), Windows 8 (64-bit), Windows 7 SP1 (64-bit)*
    Processor: Intel Core i7-6700K or AMD equivalent
    Memory: 16 GB RAM
    Graphics: Nvidia GTX 1070 or AMD equivalent
    Storage: 12 GB available space
    VR systems supported: Oculus Rift or HTC Vive
(* Windows 7 is only supported by the Vive version.)

Please note that due to the nature of the game, it is not possible to guarantee a minimum framerate, nor is it possible to guarantee that there will be no in-game circumstances in which the framerate will be slowed.

5. What is the price of the XR VR Edition?

During early access the XR VR Edition will be available for the reduced price of 39,99€ / 39,99 USD.

If you own X Rebirth on Steam already, you will get an additional 30 % discount. If you bought X Rebirth elsewhere or would like to buy the XR VR Edition from the Oculus Store*, please get in contact with us via email at info@egosoft.com (providing your Community Key*) and we will try to find a solution.

* With 4.20 Hotfix 1 native Oculus Support was added to the Steam version now. Please note that this requires Windows 8 or higher.

* The Community Key is identical to the registration code, which is printed on the back of the manual or on a small sheet of paper and which is part of retail copies of X Rebirth. If you have the GOG version, you can get the Community Key by following the steps in this FAQ article until point 4. If you bought the game on Steam directly, please connect your Steam to your forum account, as explained here and include either your forum nickname or a link to your forum profile in your email to us.

6. Why do you release the XR VR Edition as an Early Access title?

We want to bring X Rebirth VR Edition to VR enthusiasts as soon as possible and get your opinion about our vision of a space game in VR. There are mainly two big focus areas during Early Access:
  • The VR controller based UI: XR VR Edition has an exciting new method to control the game. The HTC Vive controller can be used to point at UI elements and interact directly with the cockpit. We are looking forward to receive feedback by customers on the quality of this experience and improve it further before the official public release.
  • The new Vulkan-based high performance graphics engine is still relatively early in development. This engine is designed particularly for our next big project: X4. The Early Access phase of XR VR Edition allows us to test this new technology on a wide range of different hardware.

7. Approximately how long will this game be in Early Access?

Between one and three months.

8. How is the full version planned to differ from the Early Access version?
In addition to the two main areas of focus (VR user experience and Vulkan-based rendering engine), we are also finalising some other areas of the game which are currently in Beta. For example:
  • Completing localisation to all supported languages
  • Improving tutorial missions

9. What is the current state of the Early Access version?

The game is already very robust and well tested. We intend to keep savegames compatible beyond the duration of Early Access.

10. Will the game be priced differently during and after Early Access?

We plan to raise the price when leaving Early Access.

11. Is Modding supported in XR VR?

Yes, it is. However, there are subtle differences to XR, which may require adjustments to make modifications for XR compatible to XR VR.

12. Will XR VR support the Steam Workshop?

Adding support for the Steam Workshop is on our to-do list during the Early Access Phase.

13. How are you planning on involving the Community in the development process?

To participate in the development process of VR Edition please visit the X Rebirth VR Edition Early Access forum. This will be the place to report bugs, make suggestions for the game and get updates about our future plans.

We will also try to post on the Steam forums, but can not provide the same level of service there.

14. What game content is in XR VR Edition?

XR VR Edition is based on Home of Light and also includes all gameplay features from The Teladi Outpost. So most features from the very latest X Rebirth should also be included in XR VR Edition. However, the game is designed to take full advantage of Virtual Reality and this means that we had to make a lot of changes also to gameplay elements. Here is a quick list of some of the more obvious differences:
- The universe was modified. This affects the density of stations, the highways and many other things.
- There is no external camera: XR VR Edition is always played from cockpit perspective or 1st person on platforms.
- Platform gameplay is reduced: While you can still leave your ship and walk around stations, the need for this is much reduced.
- New missions and tutorial
- The X Rebirth original plot is replaced by a tutorial to learn the game and a series of missions. The later storylines from X Rebirth 2.0, 3.0 and 4.0 including the addition of SETA, jumpdrive, weapon mods and much more are all included too.

Most importantly of course the whole UI is changed. As the launch trailer shows, the game can be controlled in a very unique way with VR controllers. See also the images in this gallery.

15. How does switching between 2D and 3D work?

XR VR Edition can be played entirely in VR and 3D. Since X games are often played for many hours in a row and allow for thousands of hours of total game time, it was a priority for us to allow quick switching between VR and non VR gameplay. The moment you take off your headset, the game will switch into a 2D mode and can be played almost like normal X Rebirth (e.g with mouse and keyboard or with the same gamepad as in VR, but not with the VR controllers anymore). With this switch comes also a different behaviour of all user interface.

Please note that the game will be paused, when taking off your headset. You have to press the "Pause" key on your keyboard to continue playing the game.

16. How do VR controller work for playing XR?

The two supported VR controllers are slightly different:

The Oculus Touch controller first has controls similar to a gamepad, thanks to the two analog sticks. Then however, it also has gesture steering the moment you rest your thumb on away from the right steering stick. With gesture steering the ship rotates with the rotation of your right hand by default.

The biggest advantage of VR controller however is how they work as pointer devices for the computer screens as well as the HUD rectangles. Everything you see you can interact with by simply pointing at it.

With the Oculus Touch, pointing is activated by just pointing with your index finger.

The Vive "wand" controller works a bit differently. You can use the two trackpads both as analog sticks and buttons and one of the two controller is permanently set to "point" mode. To click on objects you would use your right thumb on the trackpad by default.

Gesture steering can be activated with the menu button on your right controller (the one with the pointer by default) and will then work with the left controller. The orientation the controller has the moment you activate it, is the "neutral" orientation.

Gesture steering allows rotation around all three axis including roll.

17. What kind of controls / combinations are supported?

In addition to playing with the mentioned VR controller you can also play with a gamepad or joystick. Both work fine in VR. These also work in 2D mode in addition to keyboard and mouse of course. In 3D you can also combine a joystick with VR controllers for pointing.

Advanced combinations may of course require manual configuration changes.

18. Is there a manual for the game?

Yes, we created a manual for the XR VR Edition in the Egosoft wiki. You can find it here.

19. Can I use supersampling to improve visual quality?

The game does not have an option to set supersampling in its graphics options, but you can set it externally (e.g through the Steam VR developer settings). Note however that supersampling is extremely expensive on the GPU side (performance does go down!!) and that some UI elements change in size because of it. Using it a little (e.g set to 1.5) may be OK, but if you set it to a higher value some HUD elements will behave strangely.
