Q: What’s the main difference between the H3 and the P3?

The H3 and P3 both offer 3 degrees of freedom (pitch, roll, and yaw/traction-loss), but the P3 is part of DOF Reality’s Professional “P-Series”, which uses stronger, more rigid motors, smoother gearboxes, and a more robust chassis designed to withstand long, repeated daily use—roughly up to 10 hours per day in commercial environments—while the H3 is aimed more at enthusiast/home use.

Q: What does the third axis (yaw / traction loss) actually add?

The third axis adds rear-end rotation (yaw/traction-loss), which lets the platform simulate the tail of the rig stepping out during oversteer, drifting, skids, and crosswind or rudder inputs. In racing sims, you feel the car’s rear sliding around corners; in flight and heli sims, you feel rudder and slip/skid behavior, making directional control much more intuitive.

Q: Is the P3 only for racing, or can I use it for flight and other sims too?

It’s a Universal platform, so it’s designed for multiple disciplines: Racing, flight, helicopter, truck, off-road, and even custom training applications. You can mount a racing cockpit today and later switch to a yoke + throttle or HOTAS setup without changing the motion base, which is ideal if you want one rig for many types of simulation.

Q: How noisy is the P3 in real-world use?

For a motion platform, the P3 is relatively quiet—typically comparable to a desktop PC or a low-to-mid 50 dB environment under normal use. You’ll hear some motor and gearbox motion when the rig is working, especially with aggressive profiles, but it’s generally suitable for home game rooms, dedicated sim rooms, and commercial centers without being overwhelmingly loud.

Q: How much space do I need for the P2?

The platform itself has a compact footprint (roughly the size of a typical sim rig), but you should allow extra room around it for motion travel and safe entry/exit. As a rule of thumb, plan for at least a 6 ft x 6 ft area for the rig and user, plus enough ceiling height for your seat and your tallest user.

Q: What is the weight capacity?

The P2 Professional is built for heavier commercial use and is designed to handle a combined load of roughly up to 200 kg (about 440 lb) including the user, seat, and attached cockpit components. Very heavy custom builds should be discussed with us in advance so we can confirm suitability.

Q: How complicated is the setup?

If you’re comfortable assembling a normal sim rig or gaming PC desk, you’ll be fine. You’ll assemble the steel frame, bolt on the P3 motion base, mount your seat and controls, connect the control box via power + USB, and install motion software on your PC. Most users can get from unboxing to first motion tests in a few hours, taking extra time to tweak ergonomics and profiles.

Q: What’s included—and what do I need to provide myself?

You get the P3 motion base, universal frame, professional motors and gearboxes, control electronics, power/USB cables, and mounting hardware. You will need to supply your own seat, steering wheel or yoke, pedals, shifter or HOTAS, monitors/VR headset, PC, and sim software, which lets you build exactly the cockpit style you want.

Q: Will it work with Playstation and Xbox?

Yes.

Consoles operate within a closed, controlled, and proprietary platform. Currently, only a select few games, such as Grand Turismo 7, Sport, PCARs, PCARs2, AC, F1, Forza Motorsport 7, and Forza Horizon 4 and 5, send motion data from consoles using UDP over the network (as demonstrated in this video).

For these games, we offer a MagicBox solution priced at $200. To enable motion in all other games, we are developing MagicWheel and MagicPedals, which will be available in two months.

For a list of supported PC and console games, including compatibility with the latest consoles, please refer to our games list.

Q: What seat should I use with your platform?

Your seat setup is all about personal comfort and driving style. The P3 Motion Platform supports almost any bottom-mount car or gaming seat, giving you the freedom to choose what feels best.

We recommend using a bucket-style racing seat for added stability during high-intensity motion. A 4- or 6-point harness can be added for extra security, though it’s optional. For best performance, opt for a lightweight seat, as it allows the motion platform to react faster and more precisely.

You can purchase a suitable seat from Amazon, JEGS, or eBay, or even check local listings and racing communities for single bucket seats. When shopping, look for non-certified racing seats — they deliver the same experience at a much lower price compared to FIA-certified options.

For convenience and easy adjustment, we recommend using a standard bottom-mount car seat with sliders or rails, similar to what’s found in real cars. If you choose a bucket seat, you may need side-to-bottom bracket adapters and slider rails for installation.

Seat Mount Dimensions:

• Depth: 280 mm (front to back)
  
  

• Width options: 345 mm (13.37”), 375 mm (14.49”), or 405 mm (15.94”)

Q: Can I upgrade later if I start with a different DOF Reality model?

Yes. DOF Reality systems are modular, and many customers upgrade over time—from 2-axis to 3-axis, or from H-Series to P-Series. Exact upgrade paths depend on your starting model (e.g., H3 → P3 vs P2 → P3), so if you already own a DOF Reality platform and are considering a P3-level upgrade, reach out and we can help map the most cost-effective route.

Q: Is there much maintenance required?

The P3 is largely maintenance-light. Plan to:

• Inspect and re-tighten frame, seat and control bolts periodically (especially in commercial use).
  
  

• Keep actuators, linkages and the control box free of dust and debris.
  
  

• Apply light lubrication to moving joints or sliding points every 6–12 months if the rig is used heavily.
  
  

• Listen for changes in sound or feel—any unusual noise is a prompt to pause and do a quick inspection.

Q: Is it suitable for commercial use, events, or VR arcades?

Yes—that’s exactly where the P-Series shines. The upgraded motors, stronger frame, and traction-loss axis make the P3 ideal for VR arcades, sim centers, training facilities, events, and show-floor demos where rigs are expected to run for many hours a day, with many different users, and still feel solid and consistent.

Q: How motion cancellation / compensation works with your platforms?

The DOF Reality motion simulator is fully compatible with all major VR headsets. However, combining motion simulation with VR requires a few setup considerations to ensure smooth and immersive gameplay.

When your motion platform moves, your head—and therefore your VR headset—moves too. This can slightly shift the in-game view since the headset’s sensors interpret real-world motion. In most cases, this effect is minimal and won’t affect gameplay. You can see a clear example of this in action here:

Example Video

If you notice excessive camera movement or “swimming” effects in your VR image, try reducing the platform’s motion intensity in your software settings. This simple adjustment often delivers a much smoother experience.

Software Solutions for Motion Compensation

If reducing motion doesn’t help enough, you can use motion compensation software to correct the visual offset automatically.

We recommend OpenVR Motion Compensation — the most up-to-date and community-supported software for this purpose. It tracks the platform’s motion using a small tracker and removes that motion from your VR headset’s perspective, creating a stable visual experience.

• OpenVR Motion Compensation Install & Setup Guide

This software works with both base-station (outside-in) and camera-based (inside-out) tracking systems.

Supported VR Systems:

• Outside-In Tracking (Base Stations): Valve Index, HTC Vive Cosmos, Pimax 5K/8K*, and the original Oculus Rift (CV1)
  
  

• Inside-Out Tracking (Headset Cameras): HP Reverb/G2, Oculus Quest/Quest 2/Rift S**, Samsung Odyssey+, and Windows Mixed Reality headsets

Mounting and Tracking Setup

For base-station VR systems, mount a Valve Index Controller, HTC Vive Controller, or Vive Tracker directly to your motion platform. The tracker must be visible to all base stations—most users attach it near the headrest or top of the chair.

For inside-out tracking systems, mount an Oculus Touch Controller or WMR Controller on the front of the platform, ensuring it remains in clear view of the headset’s cameras.

In all cases, make sure the tracker is:

1. Securely mounted to the platform.
   
   

2. Isolated from vibration using additional weight or vibration-dampening materials like Sorbothane or soft rubber.

• Pimax PiTool Software – enable “Motion Cancellation” under settings by selecting a Valve Index Controller as the motion sensor. (Note: functionality may vary.)

Important Note for Oculus Devices:

Because Oculus devices rely on Valve’s SteamVR driver, some users may notice:

• Occasional black borders during large platform motions.
  
  

• Slight inaccuracies in rotational compensation.

Hardware (Non-Software) Motion Compensation Methods

If you prefer a hardware-based fix, there are a few effective workarounds:

• For inside-out tracking headsets: Cover one of the headset’s tracking cameras with tape to minimize tracking movement. See video tutorial
  
  

• For Oculus Rift users: Use the included DOF Oculus mount to attach the Rift sensor directly to the platform and cover the headset cameras. This prevents the headset from visually jumping but disables full rotation tracking. To compensate, reduce yaw movement in your DOF software.
  
  

• For original Oculus Rift (CV1): You can mount the sensor to the front of your DOF Reality platform using the provided bracket (mounts to the two rear holes on the wheel deck plate). Due to recent Oculus software updates, results may vary.
