Hi guys, bit of a strange problem here - using any emulator (any of robert brogalias, as well as supergnes or animaonline), I'm getting sound and framerate stuttering at consistent intervals. It seems like something is hitting the cpu when this happens, but I don't know what might be doing it - I have "betterbatterystats" and it shows that "audioOut_2" is causing 12.8 percent of partial wakelocks, don't know if this could be related.
Power saving features are all off, to my knowledge.
I've only installed very few apps, like PowerAmp, CPU Spy, titanium backup and a couple others. Rebooting the phone makes no difference, removing the SD card after copying roms to the internal memory made no difference, stopping the media scan service did nothing, I even flashed roms to Clean Rom 3.5 and it didn't change. I wiped dalvik and the other cache beforehand.
Any ideas? My tegra 2 tablet can run these emulators flawlessly at 60 fps all day!

You didn't make any under clock profiles did you? And is there a setting to change emulator settings back to default? Perhaps you changed something that made it go whack.

Haven't changed any clocks, nope. Emulator settings are default - changing frameskip to 0 makes the sound lag even worse, and allowing frameskip creates big jumps every 3/4 of a second or so. Happens regardless of the emulator used.
Forcing CPU to 1600mhz constant also has no effect.
Governor default or performance? Can't think of much else besides power saving mode but it should run fine on that too.

Doesn't seem to matter on performance or default. I'm still running the stock kernel, think I should overclock? I really shouldn't need to though when a stock tegra 2 can handle it with 0 frameskip, sound quality on max... even NES is stuttering.
I did a complete restore, no change.

No need to over clock. The emulators have run fine on my older hardware under clocked just fine. The only thing it could be is a setting jacked up inside the emulator. Nintendo and super Nintendo run easily on ARM chip sets. Fpse and n64 would give it a run for it's money though. You sure you don't have something in the background hogging up horsepower?

No problem with epsxe here smooth as butter stock 4.1.2. It's most likely the rom you're using.
Stock or Clean Rom has the same issue.
epsxe is a different story, I can run that just fine. My benchmarks are pretty standard for quadrant, I'm really out of ideas - maybe the refresh rate of the phone is slightly higher or lower than the emulator is trying to run at, causing either frame skipping or sound jumps? Any other users with an eye for framerate here noticed minor frame jumping in, say, sonic 1, 2, or 3 on MD.emu? I bet it's there, but then if you turn frameskip to 0 (like I would on my tf101) the sound goes to hell instead.
I'm using Snes9x EX and AndroGens (as well as Fpse) and don't have any of the problems you describe. Maybe you should give those a shot, and if you get the problem with those too, you might have a hardware issue?

Snes9x EX gives me the issue as well. Play mario world and run as fast as you can on level ground left and right a few times, see if the image has some slight jumps in it. Lots of people wouldn't even notice this.
Otherwise, turn frameskipping to 0. Does the sound start having issues? If it does, you have the same problem as me.
Reading around, I've found that the Note 2 apparently runs at a 58 hz refresh rate, where most everything else (including the emus) expect 60, causing the video or audio to have issues (you can have one or the other, but not both). I'm running the stock kernel, if you're running perseus it might be ok... which kernel are you running?

Oh, youre right, it does this for me too. It's really barely noticeable though, I hadn't noticed before now. I'm also on the stock kernel.
What did you mean by sound issues? Turning frameskip off maybe makes the sound a tiny biy faster at some points than it should be, but that too is barely noticeable and could just be my imagination.
But you're right, theres definitely an issue there, and I do wonder if you're right about the refresh rate.
Sent from my GT-N7105
Yeah I tried the perseus kernel, no change, sadly.
For sound issues, I get skips and stutters every couple of seconds in MD.emu, NES.emu, snes9x ex, SuperGNES, Animaonline SNES, and presumably all the others which require a tight synchronization of audio and video. Doesn't seem to be overly noticeable on epsxe, but then I haven't played any games which run at a tight 60 FPS on that one, either. Official games have no problems.
Running 1800 mhz makes no difference, either.
I've emailed Robert Broglia about the issue, I'll update if he replies - anyone else, let me know if you find a fix!

Hi, thanks for the heads up on the Galaxy Note 2, not sure why all these manufacturers are using screens with such odd refresh rates. For example, the Kindle Fire is 53Hz and the Xperia Play is 62Hz. Luckily the Nexus 7 I just picked up has a perfect 60Hz refresh rate so 0 frameskip works well on it.
In the next update I'm switching over to a more precise method for getting the device's clock so I wonder if it might help space the frames out a bit more evenly on your device. The best solution will probably be to use frameskip 0 but adjust the input audio frequency to speed-up/slow-down the audio to match the refresh rate, so I'll look into adding this for a future update.

That's very interesting that our quad-core 1,6Ghz with 2 GB ram struggles to emulate the SNES
CPU: Custom 65C816 at 3.58 MHz

It's actually not hardware power that we're lacking - we could probably emulate snes at fullspeed with 400 mhz on a single core if the emu was very well coded, and obviously we have tons more power than that. It's a function of how the emulator draws the screen and plays the sound - almost every device runs at 60hz, so every application expects the maximum speed to be 60 FPS, but the note 2 is actually 58 hz. This creates a (much larger than you'd expect) jump in the fluidity of the emulator when running with frameskip set to auto, and it creates an annoying audio jump/skip if frameskip is turned off.
In this situation, you can have perfect video or audio, but not both. One workaround is to slow down the audio to match the 58 frames instead of the 60.
If you use supergnes, you may as well email him because it happens in that emu too. Snex9x EX is way better than supergnes, though.
I can confirm the same thing is happening for my Galaxy Note II, although mine is the US Sprint CDMA/LTE variant. It also has a refresh rate of 58.002 Mhz and I use nearly all of Robert Broglia's emulators. On this device, it's either sound regularly skips with frameskip set to 0, or (nearly) perfect audio with stuttering video when frameskip is set to Auto.
This device is a beast, so this shouldn't be happening at all. :-/
Hey, everyone! I'm looking for the best way to change the resolution of the G3. I used an app that supposedly does it, and it did, but it bugged out every boot to where it would go back from 1080 to 2K, though it would think it's 1080. I know 2K is awesome, but not only can you just about not notice the difference, but game performance are GREATLY increased!! Battery life may be much more improved as well due to using less GPU power. I had frame drops on PPSSPP playing Monster Hunter in 2K but at 1080, it was always locked at 30fps. Heroes of Order & Chaos I think had worse frame drops but I hadn't gotten the chance to try it yet. Can I change the actual screen resolution, and not the DPI alone, through the build.prop file or something?

I tried that app, and used the G2 preset. It made the status bar look funny (the icons became too big for the bar) and I didn't notice any performance improvements.

That, in a nutshell, is what you get when you artificially "lower the resolution"
Hi guys, I recently bought a galaxy tab s 10.5 and I'm having issues with video playback in the native YouTube app. Basically every 5-10 seconds, I would get a micro stutter, as if the video is slightly jittery. It's definetely not buffering as the video has loaded well ahead already too.
I am using the samsung stock OS so 4.4.2 and I have installed all the latest official updates for both the OS and the Youtube app.
I have also tried a factory reset of the machine, clearing the cache and updates for the Youtube app and reinstalling. I've also tried forced GPU rendering and turning off hardware overlays in developer mode
Does this indicate there's an issue with my hardware ? It does not happen when i stream videos from my PC over wifi or any locally downloaded videos. Any help would be appreciated. Thanks.
Hmmm, never had this problem with mine when it was on stock. I usually had this problem when I underclocked my cpus and all that or when I am using to many appps.
The only thing I can suggest is use another app (viral popup https://play.google.com/store/apps/details?id=com.Mata.YTplayer ) or take it back to be safe.

Thanks, yep the youtube videos would stutter even when i freshly restarted the tablet so nothing else really is running in the background. I have tried the viral popup app except it seems to play at a really low quality setting, ,ie 1080p is not available ?
Is there anything I can test to see if its a possible hardware issue ? I ran the Antutu benchmark and got 37k which seems in line for what's expect from this tablet. Does this help rule anything out ? Thanks.
Check processes, there's probably something in the background.

I dont think so. When you play games does it lag too? Ex real racing 3 etc? Because if it cant play youtube without the micro lag, that may affect other apps. I dont get any lag while I was on stock.
If any other apps lag while playing (not on loading screens) then it may be an issue. I never had any micro lag on mine so it may vary on how you see it. Of course we have custom roms that are way smoother (CM12) but I am unsure if your issue is hardware related or the way you see it. Hope this helps!
I got youtube stuttering too for months on my TabS ST800, I tried every tricks in dev options, nothing ever changed .
But one day i tried the CARDBOARD view in the YouTube app options and then return to normal 2D view.... motion became butter smooth up to 1440p60, for any video! If closing youtube app and restarting it, it is stuttering again, until opening again the cardboard view.
Here is a test video I used to validate stutter-free playback :

You, sir, are awesome!!! I had this problem for the last couple of months on my Tab Pro 10.1, tried everything to eliminate it. Going back to Stock or GraveD rom was slightly better but not really smooth either. I was beginning to lose my sanity switching back and forth between CM11, CM12.1 and stock-rom, trying different developer-options but was not completely satisfied in the end. This cardboard-step is a temporary fix i can definitely live with. But I'm surprised that not many people seem to be effected by this stuttering or they simply don't mind at all. Hope that google is going to fix this shortcoming in the near future but meanwhile...Thanks a ton mister :good:!

I was so happy too I spent a night watching again many videos I love ! I'm glad I could share that little joy !
To answer your question, it is a shame that people are suffering from the belief that "online" videos on computer, tablets or phone *must* somewhat stutter. Well ... even trans-galactic communications in Star Wars/Trek and other sci-fi movies are depicted with stutter and even analog (!) video sync and lines issues (in 2150!!). Stutter and other digital disorders have been imprinted in the modern culture because not much effort was given to understand (and implement) that we human are analog creatures requiring a natural constant flow of sound and light, not a "best effort" variable low frame sample rate due to "unavoidable" system interrupts between storage, cpu, gpu and screen. Remarkably, Apple hardware/software was always close to perfection due to their close collaboration with the computer graphics industry for tv and movies..
It is indeed so much enjoyable when colors, contrast, motion of a clean picture hit the brain which then do not have to interpolate, filter dynamically and overcome an unpleasant stressfull and therefore tiring "motion picture"
So far only Sony with its X1 graphical processor in TVs is IMO able to achieve a minimum of digital artefacts while interpolating and displaying moving pictures. HD was a attempt to increase resolution (but we lost many qualities that the oldest of us enjoyed with CRT tubes). UHD must bring "better pixels" back with constant higher frame rate, higher pixel resolution and higher color resolution and dynamic range.
I hope to say bye bye soon to "flicks" = flickering judderish stuttering color-ish moving pictures.

Hello guys,
is there a way to lower screen res to 1080p by default (for system and everything running)?
Thank you
You can google "wm size" and "wm density", for 1080p you might as well set the dpi to 420. I don't recommend you do this on stock rom though.
If you think this can help you save battery life, it won't.
If you want performance, the gpu is strong enough for most apps that you probably won't notice any different between FHD or QHD. For 3D gaming, HTC's boost+ can lower the game resolution to 1080p.
Indeed, if you change the resolution and density, they can make some apps acting weird.

It doesn't open apps faster, but it can make the UI smoother (transitions/scrolling). This is entirely subjective of course, and then there's the variables of different rom/kernel combinations
Hello the game battery booster app installed on the htc 10 does anyone seem to have this working?
My understanding is that once you add a game to the list, the game will run at 1080p instead of 1440p but so far am getting poor performance in games and when I take a screenshot I see 1440p and not 1080p reason for my lower frame rate.
Is it really hard for htc to add an overlay that pops up saying when it's enabled?
OK is they any other apps out there that will down scale games? Without root.
Thanks
I use it for all of my games and it seems to have a very minor impact on battery life for the few games I do play. I haven't had an issue with poor performance with or without it enabled.

I think the screenshot should be 1440p as opposed to 1080p as your actual screen is still 1440p (bringing actual resolution to 1080p would cause black bars on the screen which would look unsightly). The game booster probably just forces the game to render at 1080p so fewer pixels are generated and less load on GPU.
I want game booster for my htc desire 820 g + and I have lineage os 14.1 custom rom plz anybody give me
