Dev Update #41 - VRidge 2.2 Beta (Controllers & Jitter fix)

VRidge 2.2 Beta is now available

Today we're releasing beta version of 2.2 update which mostly targets high-end VR devices. Until now, Vive Focus, Daydream-ready, Gear VR and Oculus Go were performing similarly to any other mobile phone. We want to change it and utilize those devices to unlock their full potential. Some improvements are also available for older devices but the most interesting changes apply to devices below.

To learn how to join beta testing, see the article here.

Deployment status:
Viveport: in beta @ 2.2.3 (available in Viveport)
SideloadVR: in beta @ 2.2.3
Google Play: in beta @ 2.2.3 (join)



Vive Focus and Oculus Go

Vive Focus and Oculus Go should now work out of the box with mainline RiftCat/Vridge. Easier Oculus Go distribution method is not yet implemented so you'll need manual installation (via ADB) until we finish a better option. Please see this article:

Mobile controllers

Following controllers are now supported:
  • Vive Focus Controller
  • Daydream Controller
  • Gear VR Controller
Controller uses virtual arm-elbow-wrist model so even with only 3DOF rotational sensors, it feels quite natural to move and wave. You can grab in-game katana and slice those fruits in very natural motions. It also allows you to navigate SteamVR dashboard in a easy way to switch between VR apps without taking off your headset.

All controllers are built differently with various button setups. Most of those hardware buttons are unfortunately unmappable so we came up with a solution that emulates missing buttons.

As a reference we used Vive wand, which is supported properly by nearly all VR games. It has:
  • Touchpad
  • Trigger
  • Menu (button above touchpad)
  • System (button below touchpad)
  • Sidegrip (controller side button)

Mappings

We've mapped missing buttons to reflect position of buttons on Vive wand. For example, the System button is located below touchpad on Vive wand and is emulated by pressing bottom part of the touchpad on a mobile controller. Same goes for other sides.

Advanced users may want to adjust the threshold where touchpad registers emulated buttons by adjusting EmulatedControllerButtonBoundary line in vridge.cfg. Default threshold is 10% of touchpad.

"EmulatedControllerButtonBoundary": 0.1


Vive Focus Controller

Bottom button is unmappable and recenters view on system level.
  • Trigger: Trigger (0/1 only, no analog state is available)
  • Touchpad: Fully mapped to Vive stick
  • Menu: Pressing upper part of the touchpad
  • System: Pressing the button below the touchpad (same position relatively as Vive stick)
  • Sidegrip: Pressing touchpad left or right side

Gear VR / Oculus Go controllers

Controller Home and back buttons are unmappable. Long pressing home recenters view on system level.
  • Trigger: Trigger (0/1 only, no analog state is available)
  • Touchpad: Fully mapped to Vive stick
  • Menu: Pressing upper part of the touchpad
  • System: Pressing lower part of the touchpad
  • Sidegrip: Pressing touchpad left or right side

Daydream View Controller

Bottom button is unmappable and recenters view on system level. The controller doesn't have a trigger and only has one mappable physical button so it's used as trigger.
  • Trigger: Pressing the button below the touchpad
  • Touchpad: Fully mapped to Vive stick
  • Menu: Pressing upper part of the touchpad
  • System: Pressing lower part of the touchpad
  • Sidegrip: Pressing touchpad left or right side

Jitter improvements

If you're using one of the high-end devices targeted in this update, the jitter should no longer be a problem for you. We've been working on it for a while developing Vive Focus version and we found that we can apply those improvements to all high-end environments (Vive Focus, Gear VR, Go, Daydream).

Your head movements should now be instantly reflected as rotation of the view. This may cause you to see black borders where the real rendered image isn't yet caught up to your head rotation but we want to improve prediction to get rid of those too.

This should bring jitter and perceivable rotational latency to native mobile VR level. You may want to use Reliable streaming mode (in advanced streaming settings) to prevent artifacts. Previously it could cause hiccups / stutters which no longer should be the case on high end devices.

Automatic FPS adjustment

We changed the 30/60FPS switch to Native and Half-Native. This will automatically detect your device display refresh rate and set appropriate FPS to match your device.

Advanced users may override it in vridge.cfg. For example, if you'd like to use 45 FPS, use:

"Video.FPS.Mode": "Custom",
"Video.FPS.Value": 45,

Detected refresh rate is displayed in advanced video settings GUI after connecting your phone.

New FOV calculations

Field of View and aspect ratio should now be correctly adjusted to any screen aspect ratios. This may alter the way your view is aligned so if you're using custom Cardboard, make sure that you scan its QR code in Daydream settings to configure lens distortion.

Minor changes

  • Reduced VRidge's CPU load by 30-40% when using NVENC.
  • Recenter should now recenter API-powered controllers.
  • Disabled option to switch HEVC encoder in live settings view. This would freeze the mobile stream until restart.
  • Added Project Cars tutorial to Discover view.
  • Tethering tooltip no longer clips in certain localizations.
  • VRidge settings should no longer incorrectly stay on top of all windows in certain cases.
  • Mobile app should no longer crash on reconnect sometimes.
  • VRidge Gear VR should no longer become stuck on app pause/inactivity.
  • Lobby text ("Connected, waiting for SteamVR" should no longer become stuck and displayed on top of streaming window.
  • Updated Google VR SDK to 1.80.
  • Removed artificial +170cm HMD height that could sometimes cause incorrect API controller calculation when paired with headset that didn't send positional data.

Closing notes

This update changed critical parts of VRidge technology stack so please let us know if we altered something in a way that worsens your experience. In the upcoming weeks we'll be focusing on ironing out the wrinkles and bringing it to stable channel while also enabling an easier installation method for Oculus Go and Gear VR.

As always, thanks for your support feedback. We hope that you're going to have more fun using VRidge with update 2.2.

  1. Not working good for me. Using lg g4. The fov now for me is way better, yet the problem is that this version seem to use much more resources than previous cpu or gpu. Fallout 4 vr used to be smooth now becomes unplayable but mirror image is smooth. I must mention that i also use the driver4vr for leap motion and kinect. Anyway hope this version will be as smooth as previous cause new fov for mr is way more immersive.

  3. Nice update :)..

    By the way, I want to ask about vridge on sideloadvr, can it connect to moonlight too?
    Or this no jitter mode is not using moonlight?

    Which one better, with moonlight or not? ( For gear vr using sideload vr )

    Thankss

  5. I finally got the app extracted and installed to my Go. Super confusing with so many old links, different versions on my Go and naming conventions changing all the time. Anyway, the geometry is all messed up. I seem to be laying down, inches from the floor and the controllers are at my waist. SteamVR only loads if the Nolo controller is in use so I not sure if Nolo is the problem. Should Nolo be working in this version or is there a way to load SteamVR without it? Thanks!

    1. Success! I deleted all the old versions and side loaded the app again. All is now OK. Looks great! Now to dive it and try out the great new functions. Thanks!

  6. Also, my Go headset is now overheating whereas that never happened on the 2.2.2 pre-beta where geometry was fine as well

  9. When i try to launch this version it has a popup from steam saying that steam vr could not launch. I checked steam and made sure it and steam vr are both up to date. Does this mean that i have to wait for the initial release of this version or is there something i can do to fix it.

  10. This update is amazing. No more Gear VR stutter on Gear 2015 and Samsung Galasy S6. Thank you very much.

    The only weirdness with this update is that the "Recenter HMD" behavior when tapping the center button on the Gear VR pad doesn't work as it used to anymore.

  11. Where is this "Reliable streaming mode"? On the Riftcat UI or on the mobile client? I don't see it anywhere. Please help - I have pretty bad artifacts.

    HEVC appears to have a much lower frame rate then NVENC.

    Also, sometimes when switching video encoder and then starting the stream, I get a 2d surface in the VR display that looks like a clipped viewport. When starting a VR title, that viewport remains present in the VR display.

  12. software streaming is getting WAY better and the gear vr controller support is mind blowing!!! just one issue media foundation streaming is by far the worst experiance (im using a R9 270X {i7-5820K CPU}, although its a bit old the first vridge 2.0 worked fine, while 2.1 i saw some slowdown an thought nothing of it), im wondering if others have had similer issues with older cards?

    on another note:
    you guys are doing AMAZING work, the controller support is beyond perplexing, i dont know how you did it, but by god is it worth EVERY PENNY.

  13. can it support two gearvr controllers?

  14. Does honor 7a with amd radeon 4core(laptop) matches with a simracing game?

  15. So does this mean that we could use a daydream controller with a non-daydream phone and have it work? I've got a Galaxy S6, which of course won't do daydream or anything, and I don't have cash for a Gear VR, but I could get my hands on the daydream controller. Would it still work then?

  16. Is nolovr not working in this beta? I have an s9 with gearvr, nolo headtracker is plugged in, the prompt comes up and then a grey screen followed by the oculus home starts up instead of any stream. Without nolovr the vridge stream works.

    1. I have the same on s7 + gearVR + Nolo

    2. Yeah, I have to use nolovr assistant on the PC and plug the headtracker into the long USB and stream to the gearvr for now. Maybe next update will bring nolovr standalone

  17. I'm having a problem when trying to click Play button and VR server just stop working, everything is updated and freshly installed, any ideas how I can get this beta to work? I'm using a S7 with GearVR. Thanks.

  21. The main purpose of education is to help students gain the knowledge and skills so that they will be able to function in society. Students need to be provided with the necessary skills so that they can learn to become productive citizens. There are many advantages that are associated with receiving an education. Students will be able to contribute to their community and help make it a better place to live. Education basically helps shape society because it helps students learn to become more sociable and helps them develop relationships with their peers. Students will be more qualified for different job positions if they have a good solid education. Education is vital to each student’s life, therefore, by working hard to provide the best instruction possible will help train students to become future leaders and will lead to a better life.

    Education is essential to every student’s life as well as their future. Students can have a prosperous life by receiving a good quality education. My thoughts are that students need to learn from the books along with other various materials just as I did while growing up. The classroom curriculum should be decided by their teacher and the teacher should set clear goals as to what is expected from the students. Students should work hard to achieve their goals because it will certainly be worth it in the end. According to essentialism, ‘Schools should not radically try to reshape society but schools should transmit traditional moral values and intellectual knowledge that students need to become model citizens’. Read about education help at School Uniforms benefits . The school should stress the importance of values because some children are not taught these at home. Teaching children good values helps build their character and helps them become respectable people. In regards to education, I think society is important because this is a place where we all live so we should work to make it a better place.
