Will VR make me feel sick?
VR shouldn’t make you sick!
Every experience in VR needs to be optimized for comfort. During your next VR experience, verify that the images in the headset display with no lag or jumping when panning quickly or walking. In desktop VR, low frame rates – which manifest as judder or lag – are the primary cause of discomfort for users.
This means that for users who are sensitive, a more powerful graphics card and computer are the best way to prevent even momentary drops in frame rate.
How is Virtual Reality used in AEC?
Virtual reality is being adopted at an impressive speed within the architecture, engineering, and construction (AEC) industries, plus throughout many of the allied design professions including, landscape architecture, interior design, stage and product design.
Below are some of the ways that virtual reality is actively being applied by our users to their work.
- Quickly explore and iterate on conceptual options
- Develop client trust early on in the project
- Provide immersive review environment
- Quickly generate realistic 360 panos to share progress reports through mobile devices
- Create materials for RFQ’s and submittals that impress the jury and quickly communicate vision
- Bridge gaps in communication between stakeholders and design team
- Generate VR walkthroughs to engage public audiences
- Facilitate conversations about spatial implications
- Facilitate internal reviews in True-To-Scale environment
- Receive critical buy-in and feedback from stakeholders by presenting the vision for the design in an easy to review manner
- Quality Assurance and Control
- Reduce built mock-up costs
- Solve complex coordination issues by placing consultants within VR spaces
- Evaluate the implications of value engineering on final design in 3D environment
- Identify collisions, conflicts, and mistakes in an intuitive manner
- Test modularized systems prior to fabrication for accuracy
- Onboard construction team to project design and intricacies with VR walkthroughs
- Reduce change orders throughout the entire construction phase
- Reduce time spent on site solving minor issues
- Increase on-site safety by testing phases and maneuvers prior to implementation
- Provide a visually intuitive method for training maintenance staff and operations team
- Provide access to data without knowledge of specific software
The list above is short of complete and only highlights some the primary ways that virtual reality is being integrated into AEC workflows.
The Importance of Frame Rates
One of the biggest technical challenges of VR is delivering content at a high enough frame rate to accurately “trick” the user into believing he or she is experiencing the external world. Studies have shown that in practice, any VR setup that generates frame rates below 90 frames per second (FPS) is likely to induce disorientation, nausea, and other negative user effects. The lower the frame rate, the worse the effects.
Thus, the goal for VR developers is to target 90 FPS at all times in their software. On the hardware side, this means that using a VR headset like the Oculus Rift or HTC Vive requires the high processing and rendering capabilities of a “VR-Ready” PC, which mostly boils down to a powerful graphics card (GPU).
VR CAVE System
What is a CAVE SYSTEM?
A cave automatic virtual environment (better known by the recursive acronym CAVE) is an immersive virtual reality environment where projectors are directed to between three and six of the walls of a room-sized cube.
Check out ID Architects CAVE System using VRcollab:
Wall Projector (1 per wall)
- Projector combines bright projection and XGA resolution — perfect for installation in auditoriums, lecture halls and other large venues.
- With 8,700 lumens of color brightness and 8,700 lumens of white brightness, makes content shine, even in ambient light.
- Flexible installation and Features, with seven optional lenses, lens shift, Curved Edge Blending, Portrait Mode and 360-degree projection features.
- ***Edge Blending; Use multiple projectors to overlap images, and there are no bright spots where the overlap occurs – providing dynamic, seamless projection

We suggest wall mounting your HTC Vive base stations for the best experience or, for portable setups, mounting them on tripods with this tripod pivot arm or this one.
Running the HTC Vive requires a computer with powerful graphics capabilities. Refer to our recommended specs to see if you need to upgrade your computer.
Virtual reality requires extremely high-performance computer hardware in order to deliver the frame rates required to replicate the external world (essentially 90 FPS at all times). The requirements for Enterprise VR software are especially high. To get the most out of VRcollab, your PC needs to be substantially more powerful than a typical CAD workstation. This also means that not all consumer-grade VR setups will allow you to take full advantage of all that VRcollab has to offer.
We recommend that you thoroughly research your options before investing in a VR machine. However, at VRcollab we have a few favorites:
- High-end Laptop: MSI GT73VR with GTX 1080 GPU
- Midrange Laptop: MSI GS63VR with GTX 1060 GPU
- High-end Desktop: MSI Aegis 3 VR7RE-012US with GTX 1080 GPU
- Midrange Desktop: ASUS G20CB-DB71 with GTX 1070 GPU
The VR industry is rapidly evolving, so please be cautioned that these machines are only suggestions. Not sure if your PC meets these requirements? You can download this tool from Oculus to automatically scan your system.
Note: Oculus, which has many consumer users, has different minimum requirements than VRcollab. It is necessary to cross-check the results of this tool against the minimum requirements listed on this page.
For HTC Vive users, HTC has a similar tool that is available on Steam.
The full recommended specs are:
- Graphics Card: NVIDIA GTX 1060 equivalent or greater
- CPU: Intel i7-6700 equivalent or greater
- Memory: 16GB+ RAM
- Video Output: Compatible HDMI 1.3 video output
- USB: Ports 3x USB 3.0 ports plus 1x USB 2.0 port
- OS: Windows 7 SP1 64 bit or newer
You can compare the performance of different GPUs (Graphics Cards) here: Passmark GPU Comparison.
