X Rebirth Virtual Reality Edition - FAQ

Post by X2-Illuminatus » Thu, 27. Jul 17, 19:51

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:

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.If you have problems playing with the Oculus Touch controller, it is also possible that you are not running the right version of the game. See below on how to start the Oculus version!


1. On which platforms will XR VR be released?

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


2. Which VR headsets and controllers are supported?
The Steam VR version of the XR VR Edition supports the HTC Vive (headset and controllers) through OpenVR (and also other headsets, see below).
The Oculus store version runs on Oculus Rift and supports the Oculus Touch through the Oculus API.

We are however ALSO providing an Oculus build on Steam for customers to choose from. This build does 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 (see details about controls further down!)

If you have problems playing with the Oculus Touch controller, you may by accident be playing with the wrong version. In the Steam frontend you can right click on X Rebirth VR Edition and select "Launch X Rebirth VR Edition in Oculus VR mode"!

The game is reported to also work on many other headsets, like the Microsoft Mixed Reality Headsets (see next answer!), but without VR controller. We can not guarantee it to work on all such devices.
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.


3. How do I run the game with VR-Headsets without proximity sensor (e.g. Mixed Reality Headsets or OSVR-Headsets)?

To run the game with Mixed Reality Headsets (Microsoft) or Open-Source Virtuality Reality Headsets, you have to start the game with the command line option -openvr_force_proximity.
(To do so in Steam right-click on the game entry in your library, select "Properties" and click on the 'Set launch options' button in the General tab.)

This has to be done, because these headsets do not detect when you wear them, whereas Vive and Oculus switch the mode between 2D and 3D based on this sensor. This can also be the case with other Steam VR Headsets that are not the HTC Vive!


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. 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.


6. Will XR VR support the Steam Workshop?



7. 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.


8. 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.


9. 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.

This video demonstrates different control modes:

10. 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 and now also use the newly added 3D mousepointer like a VR pointing device. (see here. )

Advanced combinations may of course require manual configuration changes.


11. 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.


12. 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.
