17 ms is just over 1 frame. It's completely typical even for the best devices. Because of VSync and triple buffering from Project Butter, that extra frame of latency is there regardless of how fast the decoder is. I'm trying to figure a way around it.

sys/module/DC/parameters/no_vsync
Change from 0 to 1.
This disables VSync
Cameron, can you add 2k and 4k resolutions to the app ?
i added 2k myself, since my phone is an Note 4, but everytime you update i have to change it on Android studio

That would be incredible! 4k! But has the encoder from GFE the ability to encode at such a high rate?sys/module/DC/parameters/no_vsync

Does the V-SYNC help on the lag issue?
Thanks
I don't see why not.
Apparently, this project butter function delays the screen composition to avoid screen tearing but at cost of higher latency
But there is no such settings on GFE. The client is who decide the resolution/fps.

Check out my wip_resolution_preferences branch. The reason I never merged it is because last time I tried it, GFE seemed to never set a resolution larger than the resolution of the physical screen. You'd get a 1440p stream, but it would just be scaled up 1080p if you've got a 1080p panel. It's very confusing behavior and I could never verify that GFE did things correctly.
What you mean by physical screen, the server or client screen ?
Cause i have a note 4, his native resolution is 2560x1440.
if you mean the pc monitor screen, we can easily hack through regedit.
Good News about Qualcomm Decoder Latency
I found by luck that the SDP attributes on the new GFE beta 2.4.0.9 allow the client to adjust video slicing parameters. I've released a new build that enables slicing on GFE 2.4 to reduce latency of Qualcomm devices (hopefully back to 2.1.3 levels). It will also improve the latency on the Fire TV as it's also a Qualcomm device.
The build is rolling out on Play Store, waiting for review on Amazon store, and up on GitHub now.
Remember, you MUST have GFE beta updates turned on and be running GFE 2.4.0.9 or higher with Limelight v3.1.4.
You can enable beta updates for GFE on the Preferences tab in the General pane.

Streaming over LTE with my nexus 6 on Verizon:
1080p/60fps
17ms hardware decoding latency. If I go to 720p/60fps or 1080p/30fps its even smoother
I have connection problems. I use Java client for Mac OS X, it successfully pairs with my Geforce PC. But when I press Start Stream, I get a message "Geforce Experience 2.1.1 is required", though I have the newest version of Geforce Experience installed, 2.2.2.0. Please help
UPDATE: problem solved, just forgot to turn off Windows firewall at my host PC.

Ever since updating to Limelight's latest version on the Play Store, I cannot launch any game stream. I receive GFE error 521, and nothing happens on the host PC (you can see the streamer service daemons running though). My GEForce Experience version is 2.2.2. Updating to the 2.4.0.9 beta did not solve this, so I rolled back to 2.2.2. Driver is the Game Ready 347.88. This really sucks, I use this a lot...guess I better stop auto-updating Limelight.
Do you know which version you were running before it updated? I haven't made any changes that are likely to cause that error recently.
You can try older versions from the GitHub page. I'd recommend trying v3.1.2 then v3.1.3 to see if either works. https://github.com/limelight-stream/limelight-android/releases
Yes, I downloaded Windows client and paired to Geforce Experience through the same network. But when I change network I can't connect again, the client app doesn't remember the host. What should I do?
General tips...
Hey guys, I've been trawling this thread looking for bits of info I can use to generally make my experience better. Currently I see 40-47ms hardware latency at 1080p60 compression. I'm positioned about 2/3 meters away from my router. I'm trying to reduce that as I use limelight for wireless VR gaming via the Trinus Gyre app.
I have a Note 3. I've just ordered an Asus RT-AC66U router to replace my current ISP provided router. I expect this to improve latency times (maybe not only due to the faster wireless speed but also due to the PC being hooked to a gigabit ethernet port?). Would this also resolve the 1 second stutter that I get every now and then? Or is that due to a Note 3 hardware limitation? Guess I'll find out truly when I receive and try the new router.
Going forward, which 5/5.5 inch smartphone would provide even less latency? Which processor should provide the best possible experience? Anyone tried the new Galaxy S6?
Thanks!
PS. Many thanks to the limelight devs for continued support.

If your Note 3 is Qualcomm-based, make sure you've upgraded to GFE 2.4.x. Nvidia just released GFE 2.4.1 to all non-beta users today. Beta 2.4.0.9 will also work.
Fixed my streaming problem after reloading the PC for another reason. Limelight was fine, apologies for the false alarm...poor timing of other issues apparently.

Android client - keep aspect ratio
Hi, I'm using Limelight Android client to stream old game. It works almost perfect, the only problem is with resolution and scaling. Game works in 640x480, and tablet scales it to stretched full-screen (17:10 I believe). Is it possible for Android client to scale stream while keeping aspect ratio? If it can't be configured, I don't mind changing something in client's code if it's something easy.

106Please don't ask for Moonlight help on Nvidia's forums! It's not their responsibility to support this app. Ask on this forum, another non-Nvidia forum, by email, etc
What happened to Limelight?/Why did you change your name?
On April 21, 2015, we received a Cease and Desist letter from Limelight Networks, Inc. They also do streaming services and were concerned about confusion between this project and their company trademarks. To comply with the terms of their C&D, we've decided to rename our project to Moonlight.

General Streaming Latency Information
The latency of streaming is dependent on the device you're streaming to and the network you're streaming over. Different devices have different H.264 hardware decoding latency. After streaming, a toast will show up with latency numbers. It will show the total client latency and the portion of the total client latency spent waiting for the hardware decoder. Note that the total client latency does NOT include network latency, so the real latency is higher than the number you see. The total client latency is a measure of the time that the first packet in a frame is received to the time that the frame is released for rendering on screen.
Anecdotal Hardware Decoder Latency Numbers
These are some latency numbers (from memory) I've seen on my test devices as of Moonlight Android 4.0.1. I'll try to keep updating this as I test.
Tier 1 devices:
Tegra 4 - Nvidia Shield - 5 ms - 1080p60 supported
Intel Atom/Bay Trail/Moorefield - Nexus Player - 8 ms - 1080p60 supported (may need a USB OTG Ethernet adapter for consistent performance)
Razer Forge TV - 10 ms - 1080p60 supported - H.265 supported
Tegra X1 - SHIELD Android TV - 10 ms - 4K60 supported - H.265 supported in hardware but needs changes in Moonlight to work well
Tegra K1 - Nexus 9 - 15 ms - 1080p60 supported
Tegra 3 - OUYA and Nexus 7 (2012) - 17 ms - 1080p60 supported
Tier 2 devices:
Broadcom VideoCore IV - Fire TV Stick - 20 ms - 720p60/1080p30 supported
Exynos 7420 - Galaxy S6 - 20 ms - 1080p60/4K30 supported - H.265 supported
Snapdragon S4 Pro (rebranded 600) - Nexus 7 (2013) - 20 ms - 720p60/1080p30 supported
Snapdragon 801 - HTC One M8 GPE - 20 ms - 1080p60 supported
Snapdragon 800 - Nexus 5 - 20 ms - 1080p60 supported
Snapdragon 600 - Fire TV (2014) - 30 ms - 720p60/1080p30 supported
Tier 3 devices:
MediaTek devices - Fire TV (2015) - 55 ms - 1080p60 supported - H.265 supported
Adding games/apps that aren't automatically found
You can stream any almost any game or app by adding the EXE file to GFE manually (if it's not found by the automatic app scan). Open GeForce Experience, click the Preferences tab, click GameStream on the sidebar, then click the add (+) button on the right. Browse to the app or file you want to add and click OK. You can rename the app using the edit button on the right (near the add button).
Using Moonlight as a remote desktop solution
You can stream the entire Windows desktop via Moonlight. Follow step 2 from this guide
Streaming over the Internet
Install the Moonlight Internet Streaming Helper on your host gaming PC to enable streaming over the Internet. If your router supports UPnP, you won't need to make any manual changes.
If the above tool isn't able to enable Internet streaming automatically or your router doesn't support it, forward these ports manually:
TCP 47984, 47989, 48010
UDP 47998, 47999, 48000, 48010
General requirements for current APK:
SoC capable of decoding H.264 High Profile in hardware (Snapdragon, Exynos, Tegra 3 or higher, Rockchip, and more)
Android 4.1 or higher
GeForce Experience with a GTX 600/700/800/900 GPU or GTX 600M/700M/800M (GT-series not supported)
Xbox, PS3 (with SixAxis app), Moga (B/HID mode), Shield, or Ouya controller (other controllers may work too in HID mode)
Mid to high-end wireless router (preferably dual-band 802.11n or better)
Good wireless connection to your Android device
Troubleshooting tips:
1. Make sure GeForce Experience is open, up-to-date, and that you've scanned for games.
2. Make sure your device is on the same network as your computer for initial pairing.
3. Try disabling any firewall software running on your machine.
4. Try rebooting your machine. Sometimes the streaming software gets into a messed up state where it won't work normally until the machine is rebooted.
5. Make sure your Android device has a strong wireless connection (and your PC too, if it's connected wirelessly).
6. For Internet streaming, make sure to install Moonlight Internet Streaming Helper on your host gaming PC, then run the Moonlight Internet Streaming Tester that it installs to troubleshoot further.
7. To check if GFE is working properly, try navigating to the following URLs on your GFE PC:
http://127.0.0.1:47989/serverinfo?uniqueid=1234
https://127.0.0.1:47984/serverinfo?uniqueid=1234
For those with latency issues, please see this post.
Device-related issues
Depending on the wireless chipset on your phone/tablet, you may have a bad streaming experience if Bluetooth is active while streaming. Unfortunately, there's nothing we can do about this. If you experience significant connection degradation with a Bluetooth controller connected, you could try connecting the controller to your PC (see the section above), a USB Ethernet adapter, or controller that connects directly to your Android device (assuming your Android device supports USB OTG)
Older Changes:
Demo video (a bit old now):

Downloads:
I'd recommend downloading the app from the Play Store. Updates are automatically applied through the Play Store when they are released. Crash reports also get to us automatically if you use the Play Store version and click the Report button if Moonlight crashes.
Google Play Link
Sometimes APKs are more convenient for sideloading and other things, so they will continue to be posted.
You can find the latest APKs on the GitHub page here: https://github.com/moonlight-stream/moonlight-android/releases6Moonlight Chrome Test Build (Alpha 1)
Since there seems to be some interest in this Moonlight port for Chrome, I've decided to put a binary up for testing. Please report your thoughts on it.
Working:
- Pairing and streaming
- Hardware accelerated video decoding up to 1080p60
- Game controllers (currently limited to those for which Chrome has a built-in mapping, like Xbox and DualShock controllers)
- Keyboard and mouse input (with the caveat of Esc kicking the app out of full screen)
Not working:
- No feedback when starting a stream - just be patient and wait for the video stream
- mDNS auto-discovery of PCs
- (Very) Non-final UI
- A few settings are missing
- Error handling needs work
- Controller detection can be wonky at times (try fully exiting and restarting Chrome)
To install, drag the CRX file into the Extensions (Menu -> More Tools -> Extensions) page of Chrome.
To launch, use Chrome App Launcher, the Extensions page, or just search for Moonlight on your PC and you should see it installed like a normal program.

I found by luck that the SDP attributes on the new GFE beta 2.4.0.9 allow the client to adjust video slicing parameters. I've released a new build that enables slicing on GFE 2.4 to reduce latency of Qualcomm devices (hopefully back to 2.1.3 levels). It will also improve the latency on the Fire TV as it's also a Qualcomm device.
The build is rolling out on Play Store, waiting for review on Amazon store, and up on GitHub now.
Remember, you MUST have GFE beta updates turned on and be running GFE 2.4.0.9 or higher with Limelight v3.1.4.
You can enable beta updates for GFE on the Preferences tab in the General pane.5Another GFE 2.1 status update: success!
I've figured out secure pairing and encrypted input (required for GFE 2.1) and implemented them in Limelight-common. There's just a bit more work to do for platform-specific support (certificate and private key generation and storage) on Android and PC. My PoC code was able to stream from a GFE 2.1 box over the Internet to a custom version of Limelight-PC.
I'm off for some much needed rest (4:54 AM here), but we're on the home stretch. Expect a release for Android and PC in the next day or so.
Update: It's done! Limelight Android version 2.3 is rolling out on the Play Store, waiting for approval on the Ouya store, and posted https://github.com/limelight-stream/limelight-android/releases. Limelight PC is released too https://github.com/limelight-stream/limelight-pc/releases5Moonlight Chrome Test Build (Alpha 2)
