We recommend at least a NVIDIA GTX 1080 graphics card with 8GB or better for a smooth VR experience with Enscape! For less complex projects the official requirements might suffice though.
Please choose your preferred VR device to read about Setup & Movement:

Due to its higher resolution (1440 x 1440 per eye) compared to the HTC or Oculus headsets, please refer to the Hardware Requirements that we recommend when using Windows Mixed Reality VR headsets. If you cannot meet the recommended requirements then we advise that you lower the rendering quality to medium or even draft which will allow for a smoother VR experience.
If you get distortion in VR, and you are using a high end graphics card, this may be due to SteamVR adjusting the resolution to 200%. In such cases, you should open the SteamVR Settings window, navigate to the Video options, and then check the option ‘Manual Override’ and then use the slider directly below that checkbox to set the resolution to 100%, or lower if acceptable (Fig 1.4). Anything lower than 100% may also result in a performance increase, although the image quality may decrease, and this is to be expected.

Usually, if you follow all the above steps, and have a powerful enough machine, cybersickness is not a big problem. However, it depends on the individual and his/her experience within Virtual Reality.
Some of the most common symptoms of Cybersickness include such things as general discomfort, headaches, a feeling of movement within the stomach, generally feeling odd, nausea, disorientation and dizziness.
Certain things can trigger Cybersickness, and these include age, gender, and general fitness, stability of the posture, a low visual refresh rate, spacial awareness, and sensitivity to motion.
The intensity of the symptoms of Cybersickness can be intensified by things such as visual refresh rate, position of the user, motion mismatch, field of view, motion parallax, and viewing angle.
However, there are some things you can do to try and reduce the effects of Cybersickness. We suggest the following:
To interact in the Enscape VR world, Enscape provides you with a Menu Ribbon (Fig 1.10), that is always visible, above the left-hand controller in VR.
Fig 1.10 The Enscape Menu ribbon in VR
When any of these symbols are selected in VR, an associated panel will slide out of the top of this strip displaying the related options for each menu item. You will also notice that the selected menu option is indicated with an orange bar above the selected symbol (Fig 1.10).When the left-hand controller is not in focus, after a short period of time, the menu panel will slide back down into the Menu Strip and disappear.
Teleportation functionality uses two distinct stages in its operability, and these should be observed to get the best experience from this function.
Holding the trigger (but not pressing the trigger fully down) displays the Teleportation Target Indicator (Fig 1.11).
Pressing the trigger down completely will then execute the Teleportation, if the location is available(Fig 1.12).
So, the right-hand controllers trigger will allow you to select and teleport to almost any destination visible.
Fig 1.11 The Teleportation Target Indicator, before fully pressing down on the controllers trigger, showing an available destination.
The Teleportation Target Indicator is able to penetrate doors and (some) windows (curtain wall windows are not supported yet), so you can easily reach the areas behind them.
If the pointer turns red with an X symbol when holding down the trigger and pointing at a location, this indicates that the destination is not available to teleport to (Fig 1.12).
NOTE: Teleportation does have a threshold of roughly 10 km, with an offset of some 500 meters.

The Navigation panel (Fig 1.13) contains five possible options.

To further clarify the functionality of the Recenter Tracking option, consider the following use cases:
Any views that have been created in Revit, SketchUp, or Rhino and have been marked as a Favorite (Fig 1.14) will then become available under the Presentation Mode menu in VR (Fig 1.15).
Fig 1.14 ‘Mark as Favorite’ Views in Revit, Sketchup, and Rhino.
In VR select the Presentation Mode symbol and the Presentation Mode panel will appear (Fig 1.15). This is a carousel menu containing thumbnails of all the Views that were highlighted in the View/Manage Views menus. Use the right hand controller’s trigger to scroll through and also to select the thumbnail of the View you want to display. Once selected you will be instantly teleported to that saved View location, whilst the Time of Day, associated with the View, will also be updated.

On selecting the ‘Map’ symbol from the VR Menu, a Mini-map is displayed (Fig 1.16). This is a top elevation map using True North as its orientation, which allows you to quickly select, with the right-hand controller’s laser pointer, a location to instantly transport to within your project.
Fig 1.16 The Map panel is displayed in Enscape VR. This is the ground floor of the building.
If you have a multi-story building, the related levels floor plan will be shown in the Map panel. For instance in Fig 1.17 the same position is shown as in Fig 1.16, but in Fig 1.17 we are one floor higher.

The Virtual Camera settings panel allows you to capture an image of the screen in VR. There are two types of screen capture that can be produced:
In Eye view you can capture exactly what you are seeing in the VR window, so when you are happy with the position you are in, press the right trigger on your control module to capture exactly what you are seeing in VR – but note the quality will not be the same as an actual rendering as the Eye View function is designed to facilitate a way to add notes from VR.

Fig 1.19 The Virtual Camera Settings Panel showing Screenshot as the selected method of screen capture
The second method allows you to capture high quality images whilst also allowing the framing of the screenshot through the adjustable aspect ratio of the capture resolution that is specified in the Enscape’s Visual Settings Capture tab (Fig 1.20).

You can then frame your view by moving the virtual camera.
A Preview window will show you the area you are going to capture as a lower resolution, grayscale image (Fig 1.21).

You can take as many screen captures as you want and not leave VR but please note that the preview quality is NOT the same quality as the final rendering. Also, the final renderings are being generated only upon VR being disabled in the Enscape ribbon.
Opening the settings screen will allow you to change three aspects:
