Overview Of DOF Reality H3 And P3
Both the H3 and P3 are compact motion simulator systems from DOF Reality designed for VR gaming and simulation. The H3 offers 6 degrees of freedom (6DOF) motion, while the more affordable P3 has 3DOF movement.
Some key specs:
DOF Reality H3
- 6DOF motion platform
- Electric actuators with 20” stroke length
- Supports up to 220 lb user weight capacity
- Cockpit seats or NX model without seat
- Works with SteamVR, Pimax, Oculus, HTC Vive
DOF Reality P3
- 3DOF motion platform
- Electric actuators with 16” stroke length
- Supports up to 264 lb user weight
- Cockpit seats or NX model without seat
- Works with SteamVR, Pimax, Oculus, HTC Vive
Now let’s take a deeper look at how these systems compare.
Motion Performance
The biggest difference between the H3 and P3 is the degree of motion freedom.
The H3 provides full 6DOF movement in pitch, roll, yaw, up/down, left/right, and forward/backward. This allows for highly realistic simulation of driving, flight, space travel, and other vehicular activities in VR. The wide 20” actuator stroke supports strong acceleration forces for immersive motion cues.
The P3 offers 3DOF motion with pitch, roll, and up/down movement. This allows you to feel realistic bumps, leans, and drops in VR sims. However, the lack of sideways or forward/backward motion ultimately provides a less immersive experience compared to 6DOF systems. The P3’s 16” stroke still delivers solid motion effects though.
For full vehicular immersion, the extra degrees of freedom in the H3 are a major advantage. But the P3 still enhances many seated VR experiences with its smooth 3DOF motion.
Design And Comfort
Both systems feature an open platform cockpit design for easy VR headset and peripherals integration. They use sturdy powder-coated steel construction with availability of racing, spaceship, and other themed cockpit seats.
The H3 measures roughly 59” wide x 55” deep x 77” high with a seat installed. It takes up a larger footprint than the more compact P3, which comes in at 36” wide x 40” deep x 77” high.
For user comfort, the P3 has a slight edge in stated weight capacity at 264 lbs VS. 220 lbs on the H3. Although real-world user reviews indicate both systems can accommodate individuals exceeding the specs in many cases.
The H3 also generates higher levels of motion forces, which could potentially cause more discomfort for those prone to simulation sickness. However the P3’s milder 3DOF movement is less likely to cause nausea issues.
Overall build quality and comfort is excellent on both systems according to most users. But the P3’s smaller footprint and potentially gentler motion may have advantages for some users, depending on available space and nausea sensitivity.
Setup And Compatibility
Both the H3 and P3 are designed to integrate with SteamVR hardware as well as headsets like the Oculus Rift, HTC Vive, and Pimax VR. They also work with a range of VR ready PCs.
However, the H3 offers native support for up to 4 monitors to be mounted on the cockpit for ultra-immersive experiences. The P3 does not directly support monitor mounting.
The H3 and P3 both include the necessary actuators, wiring, and hardware in one package. But setting up the H3 will be more complex given the 6DOF components to assemble and connect. Most users should be able to assemble either system in 2-4 hours following the manuals. The P3 is generally easier and quicker to set up out of the box.
Games And Software
With native SteamVR support, both DOF Reality systems can play thousands of compatible VR titles meant for seated play. This includes driving and flight sims like Project CARS 2, Elite Dangerous, Microsoft Flight Simulator 2020, and Star Wars: Squadrons.
For software, DOF Reality offers the SimTools software package. This lets you optimize motion effects for different games with advanced settings and controls. The software works on both the H3 and P3 to enhance your experience in supported titles.
There are no major differences in software compatibility. But the H3 unlocks more capabilities in titles supporting full 6DOF motion control. In 3DOF-only games, the extra features of the H3 go relatively unused.

Price And Value
The H3 retails for $8,999 for a full system with a cockpit seat included. The P3 starts at $4,999 with a seat. So in terms of pure price, the P3 provides a more affordable entry point into motion simulation.
However, the H3 adds much more immersion with true 6DOF movement, larger actuators, and 4 monitor support. For serious racing and flight sim enthusiasts, those premium features easily justify the higher price tag and deliver excellent value. The P3 still brings motion cues to seated VR for a lower budget.
In summary, the extra $4,000+ investment for the H3 gets you superior motion, future upgradeability via add-ons, and a more powerful experience overall. But more casual users who don’t need full vehicle simulation may be better served by the cheaper P3.
Frequently Asked Questions (FAQ)
The DOF Reality H3 measures approximately 59” wide x 55” deep x 77” high including the installed cockpit seat. It takes up a larger footprint than the more compact P3 model.
DOF Reality provides a 1 year limited warranty on the H3 motion simulator system. This covers defects in materials and manufacturing workmanship. Normal wear and tear or damage from improper use are not covered. Extended warranties can be purchased for added coverage.
The main difference is the addition of sideways (left/right) motion. 5DOF systems like the P3 offer pitch, roll, yaw, up/down, and forward/backward movement. 6DOF adds sideways/strafing left and right, allowing for fully realistic vehicle simulation and lateral forces.
Both the H3 and P3 support DOF Reality’s own branded cockpit-style seats. They also work with some common racing/flight simulator seats from other brands. Compatibility ultimately depends on properly fitting the seat to the motion platform size and mounting points.

The Verdict
For most enthusiasts and hardcore fans of VR driving or flight simulation, the DOF Reality H3 is the clear choice. The full 6DOF motion system paired with large actuators, 4 monitor compatibility, and future upgrade potential makes the H3 an excellent long-term investment to take immersion to the next level.
For those new to motion VR or anyone seeking a budget-friendly seated simulator, the DOF Reality P3 hits a nice sweet spot. You still get quality motion effects in 3 axes for enhancing racing, flying, and action games in VR. Just don’t expect the full realism of vehicular simulation like the H3 provides.
Hopefully this detailed comparison gives you a better sense of how these two systems stack up! If you’re still unsure between the H3 and P3, considering your budget, available space, and desire for full 6DOF movement VS. 3DOF effects. This can help you pick the DOF Reality model that’s right for your virtual reality setup.
