How Hardware Choices Impact Performance

Processor (CPU)Video Card (GPU)Memory (RAM)Storage (Drives)

The two main factors in IrisVR Prospect's performance are the CPU (central processing unit, often referred to simply as the processor) and GPU (graphics processing unit, which is the main chip on a video card). This is similar to how traditional computer games work but with a heavier emphasis on graphics - since two views have to be rendered at the same time, one for each eye - and more user inputs to keep track of.

Because of the way the workload for virtual reality is split up you need to have a good balance between the CPU and GPU. Memory and storage systems in a computer also play a role in IrisVR performance, as they do in all computer-based applications, though not as much complexity is involved in the selection of those components. What follows is a general overview of what hardware is important for virtual reality and related applications.


Processor (CPU)

IrisVR Prospect, along with many engineering and modeling applications, is heavily dependent on CPU clock speed. Only a few cores are used at a time, usually, so while having extra cores for other applications and future-proofing is good clock speed is paramount. Here are a couple of our top CPU recommendations:

  • Intel Core i7 9700K 3.6GHz (4.6-4.9GHz Turbo) 8 Core - This is one of the highest clock speed CPUs available, topping the charts for single-core performance and VR / gaming applications. It also has more cores than previous generations of Intel processors in this market segment, which helps with future-proofing and other, more multi-threaded tasks.
  • Intel Core i9 9900K 3.6GHz (4.7-5.0GHz Turbo) 8 Core - This chip is clocked just a hair higher than the 9700K, but also adds Hyperthreading. That won't impact 3Data, but if you run other applications which are able to benefit from more cores then it could help.

Video Card (GPU)

Having a powerful video card is critical for virtual reality performance as it directly impacts the ability of the computer to keep up with the high resolution and frame rate which a good VR experience requires. The initial release versions of the HTC Vive and Oculus Rift both have dual displays, one for each eye, at 1080x1200 resolution. These run at 90Hz, which is 50% higher than the standard refresh rate of monitors, and the perspective of each eye is slightly different so it is actually rendering two distinct views rather than just a single, larger display. Some VR head mounted displays also require off-screen rendering of an area around the actual display that each eye is given, or allow super sampling for better image quality, both of which require further resources from the video card. Here is a chart of four common monitor resolutions with the effective resolution of a HTC Vive overlayed for comparison:

Common Screen Resolutions Compared to HTC Vive HMD

Within NVIDIA's GeForce RTX series, the RTX 2070 8GB is a solid choice for VR. If you want to use a higher resolution headset like the Vive Pro, or plan to work with particularly large 3D models, then going to the RTX 2080 8GB is a decent upgrade - and the 2080 Ti 11GB is about as high as you'd want to go currently.


Memory (RAM)

Memory requirements for most virtual reality headsets start at 8GB, but for better results with recommend 16GB as the entry point. If you plan to run a lot of other applications as well, or work with very large models, you consider upping that to 32GB (or even more).


Storage (Solid State and Hard Drives)

With the falling costs of solid-state drives we strongly recommend using a SSD for the primary drive that will host your operating system, software, and project files. The high speed of SSDs allows your system to boot up, launch programs, and even load media many times faster than a traditional hard drive.

The main question then becomes capacity. Windows and applications like IrisVR don't actually take up all that much space, but since most users will eventually have more stuff installed than just that - plus project files and other media - we recommend a minimum capacity of 500GB for the primary drive. Further storage can also be added, either during the build or later on, but keep in mind that the more compact workstations are hard to work inside... so for those, we encourage having any extra drives included up front rather than planning to add more of them later on.
