Virtual Reality Flight Simulator Games – What You Need to Know

Virtual Reality Flight Simulator Games

There are two types of virtual reality flight simulator games. One type includes titles with native support from the developer. The other type includes titles that need third party technology to work with VR. Virtual Reality brings with it exciting possibilities, but also significant performance challenges for developers.

Why is VR challenging for developers? Frame rates. Any software must provide at least 60 frames per second in order to be used with VR, and preferably over 90. Flight sim software has always struggled to provide high frame rates because of the expansive and detailed environment it models. Consequently, the software choices come down to a trade-off between performance and features, and I’ll elaborate on that more next.

Titles with Native VR Support

First of all, here are the flight sim titles with native VR support (as of Nov 2017): DCS World (modern military), IL-2 Sturmovik and War Thunder (both WW2), Aerofly FS2 (civil and military airplanes) and Elite Dangerous (sci-fi). These titles have good VR performance, which means they operate at high frame rates and look stunning.

The tradeoff is their limited features for flight simmers. They do not have global maps, weather options are limited, aircraft systems are not completely modeled, and they have limited choices in aircraft. Now before I get angry messages, DSC World is deeply detailed in aircraft systems and environmental fidelity, but only with the limited choices of aircraft and geographic area.

Furthermore, I’m not saying these virtual reality flight simulator games are undesirable. Each one is spectacular in its own way and the immersion is breathtaking. Indeed, once you try these titles in VR, you may never go back to a flat screen again.

Titles Without Native VR Support

The flight sim purists will point out that the titles I mentioned above were games, and the ones I discuss next are SIMULATORS. The three full-featured titles are Prepar3D, X-Plane 11, and FSX Steam. Can you fly these in VR? Yes, but only with Fly-Inside software and a Leap Motion device. Again, performance becomes a problem because these titles can’t hit consistently high frame-rates for VR.

Lastly, Dovetail Games’ Flight Sim World currently has no VR capability at all.

 

Using Virtual Reality in the Real Word

Once you strap on a VR headset, that is your new world. Forget using keyboard commands, you can’t see the keyboard. You may even lose track of your mouse or beverage. Everything must stay in the same place so you can put your hands on it without looking. This is why I strongly recommend a framework to hold your controls in place, like the DIY Side Joystick Frame, the DIY Center Joystick Frame, and the DIY Easy Helicopter Collective. These projects are for serious flying, so they include a mounting point for rudder pedals.

Add a trackball mouse, because it is priceless for VR flying. Use a drink holder and note it is hard to drink from a regular travel mug while wearing a VR headset. Use a cup with a straw. Also, set up a fan because VR headsets are warm and they make you warm too.

Virtual Reality for Flight Simulator

Virtual Reality for Flight Simulators, Is it Time? – Part 2

Is is time to take the leap into Virtual Reality and incorporate it into your flight simulator? Maybe not, depending on what you like to simulate. In this article I continue my exploration of Virtual Reality for Flight Simulator and discuss Flight Simulator X, War Thunder, some physical and financial issues, and system specs. In Part 1 of this article, I experimented with DCS World and Elite Dangerous in Virtual Reality. You can read it here.

 

FSX sample

Flight Simulator X with FlyInside and Leap Motion

This is the big one! FlyInside FSX is an ambitious project to make Microsoft Flight Simulator X compatible with VR. Leap Motion is an infrared sensor that can detect the location and position of your hands, so you can see your hands in Virtual Reality. Put FlyInside and Leap Motion together and you can activate airplane switches with your hands in the FSX virtual cockpit! If that is difficult to imagine, here is a video that demonstrates it.

Disclaimer: I discovered it’s really difficult to take good screen shots in Virtual Reality for flight simulator, so for this article I borrowed representative pics from other sources. This has no impact on the validity of my findings.

FlyInside FSX is a rather new project and even though it didn’t work for me, I still think it’s important to support the developer. The first flight I tried was the simple default flight around Friday Harbor in a Piper Cub. It was pretty cool to look around in VR, as long as I didn’t move my head too fast. Virtual Reality works best when the images are rendered at 90 frames per second or more. The stock FSX can’t consistently provide fps nearly that fast, but FlyInside has a trick to get around that. Unfortunately, it didn’t work well enough. When I moved my head, the images lagged. Lagging equals motion sickness, remember that. When the images you see with your eyes do not match your head movement, you can get motion sickness very quickly. I’m not prone to motion sickness, so I was able to do a few takeoffs and landings without barfing, but the experience is not nearly as good as VR in other flight sim software. On the other hand, I found that it’s easier, and it feels more realistic to land an airplane in VR.

I tried to trim the airplane during flight, and that’s when it all went sour. Recall that I also used Leap Motion, so I could literally see my hands while flying in the virtual Piper Cub. This is supposed to give me the ability to manipulate controls and switches in the cockpit, much like it’s possible now with the mouse. I reached out to adjust the elevator trim and…. FSX crashed. I re-booted and tried the same thing again… another crash. And that’s it. After two crashes, I’m done.

Conclusion: support this project. I did, but I won’t use it again until it’s more reliable.

 

WT sample

War Thunder

Combat in Elite Dangerous made me miss my old online squadron. I had never played War Thunder before, but it’s free to sign up so I enlisted and went back to World War 2 for the first time in several years. This game was much more menu-friendly to VR than DCS world was. I wasn’t familiar with War Thunder, so it took a while to get my controls and buttons assigned. Apparently, the game isn’t expecting many users to have rudder pedals, so that really throws it for a loop.

Once I had my controls set up, I launched into battle with my pathetic P-26 Peashooter (that’s how you start out). Even with my crappy plane, I had blast in War Thunder. I had a level of spatial orientation that I’ve never had before in a flight simulator. VR is a game changer for air combat because of the way I could look above, below, behind, and around the cockpit frame. Even though I was a rookie, most of the guys in the Arcade level don’t know anything about energy fighting so I was able to use that to my advantage and I leveled-up rather quickly, or at least I think I did. The flurry of levels and tokens and things are still a mystery to me.

War Thunder also has a Realistic mode that I tried, but I didn’t get my controls completely set up. A Saitek X-52 looks nothing like the controls you would have in a WW2 airplane, so this means I need to assign mixture, prop and some other functions to the knobs on the throttle, which I wasn’t all that excited about. I’m sure I’ll revisit that at some point.

I experienced my first strong physical reactions in Virtual Reality while playing War Thunder. My heart was pounding and I was sweating profusely during combat. I had to take breaks between sorties for my heart rate to come down and I pointed a fan at myself to cool off. This is serious fun!

Conclusion: I will only play War Thunder in VR. That’s how good it is.

Edit: the recent update of War Thunder failed because the sound no longer works. As a result, I won’t be playing this again until they fix it.

 

Matrix: Virtual Reality for Flight Simulator

Here is a summary of my findings with the flight sim software. Read on for financial and physical implications.

Virtual Reality: Financial Issues

The FlyInside developer recommends FSX Steam because it works better with FlyInside for some reason. I would like to try it, but I’m simply out of money. Virtual Reality costs real money. It is expensive. The Oculus Rift headset was over $600 with shipping, but I also needed a new computer to run it. I shopped smart but still spent over $1160 on a new gaming computer (specs below) and that still wasn’t enough. I’ll need to spend another $600 on a new graphics card before I can run the Rift at high definition 1080p. I bought Leap Motion on sale, but I can’t use it because of the problem with FlyInside FSX. I couldn’t afford to even try Aerofly FS2.

Notice that Virtual Reality did best with games, not simulators. Flight Simulator X was not usable and X-plane doesn’t support VR at all. Think long and hard about spending your money. VR is for gaming, not for simulating.

Virtual Reality: Physical Issues

You can’t wear glasses with the Oculus Rift. Well, technically you can, there is an awkward way to do it, but the headset will push the glasses against your face, which is very uncomfortable. Realistically, it’s contact lenses or nothing and that’s just the way it is right now. Maybe there will be helpful remedies in the future.

Motion sickness is a risk if you’re prone to motion sickness in general. If you typically feel nauseous in a plane or boat or car, you may feel the same in VR. Furthermore, if your computer can’t render VR in 60 frames per second (at least), you may feel nauseous in Virtual Reality for flight simulator. Luckily, motion sickness if easily remedied because you can just take a break and remove the headset for a while.

Pounding heart, sweaty armpits, residual headset heat, dry eyes. Clinical flight simulator research shows that pilots start to have involuntary physical responses to professional flight simulators when the images are rendered higher than 60 fps. In other words, their palms sweat. In my experience, my heart was pounding, I was breathing heavy, and my whole body sweat during combat in War Thunder. I took breaks between sorties to calm down, it was that intense. Sometimes my eyes would get dry in VR because I probably don’t blink as much as I should. Lastly, the Oculus Rift headset gets warm during use, so I needed a fan blowing on me to help me stay comfortable. That’s unusual for me, I typically have a lower than average body temperature.

Virtual Reality: Emotional Responses

I didn’t expect to have any emotional reactions to VR but I did. Virtual Reality for flight simulator wasn’t the only thing I tried, I also looked at some 360 degree videos. When you view these videos, it’s like you are inside the video and you can turn any direction to see what’s happening around you. Several little clips are included in the Oculus library.

One clip showed a young couple on a gondola ride in Venice. The camera was in the boat with them so it seemed like I was riding along with them too. It was a vacation I can’t afford in a city I’ll probably never visit and yet, I was there… virtually.

Another 360 video clip showed a family in Asia somewhere and their house was basically a little shack on stilts in the water and again, I was there… virtually. I was reminded of how lucky I am to even experience VR because my computer and VR headset probably cost more than their annual income.

Virtual Reality for Flight Simulators, is it time?

Virtual Reality for Flight Simulators, Is it Time? – Part 1

Is a Virtual Reality headset worth the money if you are a flight simulator enthusiast? It depends on the type of simulating you do. In this article I’ll tell you about my first month with the Oculus Rift headset and Virtual Reality for Flight Simulators. I’ll discuss the four different flight sim platforms I tried with VR and also the physical and financial impacts of these experiments.

The first thing you should know is this: Virtual Reality is a game changer. Accent on the word “game.”  I’ll go into more detail in a moment.

The second thing you should know: Virtual Reality costs real money, plenty of it.

Upgrade the Gear

I started my maiden voyage into the world of Virtual Reality for flight simulators a few months ago when I ordered an Oculus Rift. They were on backorder at the time, but even so, I received mine a full month before I expected to. VR headsets need substantial processing power to work effectively, so I bought a new computer at Best Buy and the specs are at the end of this article. I also bought a Leap Motion sensor while it was on sale so I could experiment with FlyInside FSX. If none of that means anything to you, don’t worry, I’ll come back to that in a minute.

Upgrade the Controls

I also upgraded an F311 Side-joystick HOTAS by making the control platforms wider to better align the controls with the armrests of my chair. Furthermore, I added a trackball mouse and a drink holder (don’t fly thirsty). I also raised the reinforcement bar so I could use my favorite rudder pedals and attached all fittings with self drilling screws. I used this F311 frame with great success, I can’t VR without it.

For these experiments, I said goodbye to my trusty Saitek switch panels and keyboard mods… you can’t see them while wearing a VR headset. Now, come with me as we explore Virtual Reality for flight simulators…

Elite Dangerous

My first flight in VR was in space and it was breathtaking but just a bit disappointing. Everything worked correctly, but I found that my graphics card could not power the Oculus Rift at 1080p, so I’m temporarily stuck at 768 until I can afford a more powerful graphics card. Even so… I said the experience is breathtaking and it is. You have stereoscopic vision in VR, just like you have in real life. Your left eye and your right eye see slightly offset views of each object, so this is what makes close objects look close and far objects look far away. In Elite Dangerous, this means I could for the first time, sense the size of the spaceship’s flight deck. I could look down at my arms in the game and see how close they are and then look outside and comprehend the enormity of the space station.

The game isn’t on a screen any more, it’s all around you. You’re inside the game. This is most obvious in combat because you can look up and back and over your shoulder at your enemy. You also should be fully HOTAS so all aircraft functions are assigned to the buttons on your joystick and throttle because it’s too inconvenient to use the keyboard. That means you also have to memorize all your button assignments. One of the great limitations of VR is that you can no longer see real-world buttons and switches. However, you can use Voice Attack to simply speak commands to your spaceship. For example, you can verbally tell it to extend landing gear, and that is perfectly plausible in this futuristic environment.

Conclusion: from now on, I will only play Elite Dangerous in Virtual Reality. That’s how good it is.

 

DCS cockpit

DCS World

I couldn’t wait to try DCS World with the Oculus Rift, but unfortunately it didn’t go as smoothly as Elite Dangerous. First of all, the DCS menus were very difficult to use and in some cases, they just didn’t work at all. It was a time-consuming chore just to set up my Saitek X-52 HOTAS controls and rudder pedals. I flew several tutorial missions, but many of the lesson tasks required the use of keyboard commands, so I had to put my keyboard on my lap. I could kind of see the keyboard in the gap between the bottom of the Rift headset and my cheek, but this is not a reasonable option. Perhaps I could have assigned specific functions to HOTAS buttons, but there are so many of them and, again, navigating the DCS controls menu in VR is a crapshoot at best.

Disclaimer: it’s really difficult to take screen shots in Virtual Reality for flight simulators, so for this article I borrowed representative pics from other sources. This has no impact on the validity of my findings. 

I appreciate the realism of DCS World, but lifting the Rift headset repeatedly to look at a paper checklist or the keyboard is a no-go. I applaud the young man in this video for diligently looking at his checklist, but every time he lifts the headset with one hand, the Rift lenses come in contact with his forehead. Be very cautious with the Rift lenses, they are delicate! Repeated exposure to sweat or hair or grease can damage the Oculus Rift lenses.

DCS World looks astonishingly great, even if it’s not fully usable. One of the aircraft I selected was the TF-51 Mustang and I really felt how cramped the cockpit is. I also tried a few landings and found them to be a more realistic experience in VR than my previous experience. Instrumentation was a little hard to read because of the lower resolution required of my graphics card. I would love to try all of this again at 1080p.

Conclusion: I won’t play DCS World again in VR until there is some work around or fix for the menus.
