I often watch a movie or TV serie on my phone before sleeping, but I have noticed that the video payback is not always smooth and there are slight stutters as if the G3 doesn't have enough power to play back full HD high bitrate, particularly in Matroska formats. So whats up with this? I know the G3 is plenty powerful to be able to play without stutter, so could it be some kind of power saving feature holding the cpu performance back and causing stuttering? This is ridiculous to be happening with a flag ship phone! Any ideas on how to fix this?
I assume these are on your phone and not on your network or the web or something. Have you seen this thread?

You could try turning off the throttling (at your own risk).

I will try that and report back, the only strange thing is that my phone does not get warm at all when watching video, so I don't think its a problem with temperature, I usually watch at very low brightness.
I tried turning off the throttling features and it made no difference. I think maybe the stock video player is just not optimized well, so I am going to try VLC and see how that goes.
I'm not sure if this will be of any help, I hope VLC works for you. I use BS Player on my 2012 nexus 7 to play my 1080p bluray rips(at whatever bitrate the pirate scene rips at). I would suggest trying that one and to play with the hardware decoding options if things don't seem smooth with it.

You could try that. May work. The other option would be to turn off the power saving feature LG put in that limits the cpu. It likely turns down for easier frames and then has trouble with frames with more detail, since compressed video is variable like that. I'm not sure if anyone has completely disabled this though, and it may have a huge impact on battery life.

After rooting and doing a hard reset my nitro is significantly faster, but I'm still experiencing stuttering on high quality YouTube videos. It doesn't occur for normal video payback, but does seem to happen using maps or graphics intensive games. The playback will slow down and then go very fast to catch up. Is this just the gpu having a hard time keeping up? Or is this a software problem that can be alleviated through either an update or a fix on my part?

I'm experiencing this myself. I can watch vids on the desktop version of YouTube at 720p with out a problem anything but the app seems to stutter from time to time.

What particular graphic intensive games are you having trouble running smoothly?
Dragon Fly! ran smoothly, although it gave an "Async" notice that I never saw on my Atrix 4g. Fruit Ninja had issues with lag and Minecraft would stick entirely for a few seconds, although I realize that game is in alpha.
Additionally, Google Maps will often stick when loading up traffic, satellite and other info when trying to move or zoom.
Just some thoughts, trying to see if anyone has similar experiences.
I've been having issues with the GN2's performance while scrolling menus and playing games. Jetpack Joyride is the most noticeable, with it stuttering all throughout. This even happens with simple games like Scramble with Friends, making it more unresponsive than it should be. Plugging the phone into the wall seems to lessen the stuttering. It also appears that the longer the app is used it slightly lessens the stuttering.
Strangely, frame rates seem better while playing 3D intensive apps like Death Dome.
My Galaxy S2 did not have any of these problems throughout its entire life span, ever. It did everything buttery smooth, which is strange considering this phone is supposed to be more powerful. The stuttering isn't terrible, but it's definitely there, and I'm not exactly happy with it.
This occurs no matter how many idle programs are closed or what Launcher that is used. I've used TouchWiz, Launcher Pro, and Go Launcher.
Is anyone else having this problem? Is this something that can be fixed or should I return the phone for another?

Wow, hahaaa! Thanks a lot! That's silly to think that works. I felt like it was some sort of power related issue and was sooner going to overclock the CPU than suspect that option.
It didn't work immediately after disabling it, but once I restarted the phone everything was fine. THANKS AGAIN!!
I have the WatchDog app installed on my S3, which allows me to see what processes are consuming unusually high CPU usage.
I noticed a pattern where the stock Video Player is consistently going over 50%, when I'm not using it. It just spikes for no reason. I don't have any movies on my 16gb microsd card. I just have the vids I recorded using the stock camera.
I'm not sure what could be causing this weird behavior. Luckily, this WatchDog app let me kill it when this happens, but I just think it's odd, and annoying. Anyone have a clue on how to fix this?
FYI, I'm using the stock rooted Jelly Bean ROM, with some bloatware removed manually. No custom kernel.
Thanks in advance.
I get exactly the same issue. Watchdog alerts me of 86% CPU usage and 'Usage Timelines' confirms it.
After investigation, I discovered that it was something to do with the media on my phone. I had guessed the problem was with some background indexing service so I deleted all (video) media files and the problem immediately went away.
I have noticed a correlation between my taking a video and this problem surfacing soon after. If I go into media and delete the most recent video, the problem stops. So it's not just dodgy media that I have downloaded onto the phone, it's also media *created* by the phone itself.

Just today i got the same warning, when i was shooting some video footages and attached gs3 via usb to PC for charging. A few minutes after connecting got that WatchDog alert.
Same issue here. Has anyone come up with a solution other than deleting video files?

I tried freezing the Video player app with Titanium, but then of course, I needed to hunt down another video player. there are lots of free players out there, but most are ad supported, and I don't want to have to buy one to get around this problem. Another solution is using the free ES explorer's video player (built-in) but I didn't really like that either (forgot the exact reason).
For some reason, it hasn't been spiking much lately. I've just been living with killing it via Watchdog.
EDIT: Solved by restarting the device.
When playing very large files (h264, 1.5h movie encoded into 7GB file, high profile, 1080p of course) I get high CPU usage in some scenes and dropped frames. Is that too much for Fire TV CPU? Why is CPU usage that high if Kodi uses hardware acceleration? (I tried both libstagefright and mediacodec, they seem to give the same result while software decoding is a bit worse).
Codec info shows no dropped frames, but it's visible that the video is choppy.
Cache is full (although sometimes has trouble filling up - but it doesn't seem connected and is not causing real problems).
Mb/s: usually about 10MBit/s when it happens (doesn't seem that much really).
Cpu usage: all 4 CPUs are over 90% when it happens.
Drop: close to zero, but the video is visibly choppy.
Is this normal?
From specs Fire TV should handle up to 20MBps...
PS. Anyone willing to test those files: http://jell.yfish.us/ - 20Mbps works fine for me with high CPU usage, 50Mbps is choppy like hell.
I have "dc:ff-h264" in the CodecInfo which from what I read means it's software decoding. In that case I am stunned how well it works, I thought it was surely hardware decoding since it had only slight problems.
If this is really software decoding only then the CPU in Fire TV is very powerful. My old PC wouldn't be able to handle that.
I will update this post when I find how to force hardware acceleration to work.

That is software, you need to enable hardware in the system config. It should be on by default, but I am not certain. Check under video->acceleration and be sure to enable expert settings. Decoding Method should be set to hardware. And you can play with Allow libstagefright, MediaCodec, or both.
Edit: With both enabled I just tried JellyFish @ 50mbit and it played flawlessly. I'm on Kodi and Amazon Firmware 51.1.4.0
Thanks for the JellyFish test. It sounds awesome that it works even at 50MBit.
I have hardware acceleration turned on (I tried all options there) but for some reason it doesn't work - maybe I'll switch to SPMC if I don't find a way to force it - right now I use Kodi nightlies.
PS. Restarting the device helped (at least for now). I will observe how it will behave in the future. (for now both amc-h264 and stf-h264 work) I had the device running for a few weeks before that, maybe something got locked.

I can confirm the same. Not rooted AFTV, Kodi official release, both hardware options enabled and latest firmware (in Germany)
Thanks. After restarting the device it works for me too. Turns out it might be good to restart it from time to time. Stupid me for not trying it right away.
I'm kinda desperate at this point and don't know where else to ask. So I'm trying to play pubg in the lowest graphics settings possible with extreme fps. In my previous note 9 never had a problem, but now the framerate drops a few seconds into the game. I've not been able to fix this, even did a factory reset. Funnily enough, I went to developer options and enabled gpu watch to see what's going on, but the game ran smoothly. Then as soon as I disabled gpu watch, the game went back to ****ty framerate. Any suggestions will be highly appreciated.

The only way to play pubg with smooth/extreme frame rate is by using the gpu watch. Just leave it on. It'll turn off when phone is reset. Its the only way. I don't know why samsung did this, tons of ppl must think its a horrible phone. I bet tons of ppl have no idea about gpu watch
