How to eliminate ALL scrolling lag and YouTube/HD video stuttering

Google's project butter is the best thing to ever happen to android in terms of visual polish but I was curious as to why it still was jittery despite all its freaking gpu/cpu cores.
Turns out full gpu acceleration is not on by default so I went into development in the settings and forced 2d gpu acceleration. Disabling the overlays does more harm than good it seems.
This thing is BUTTER. Try this in rom toolbox, before scrolling was jittery and after it was perfect. Same with tapatalk.
What it breaks:
Google movies
Moon reader+ fonts

Should work out for the most part, but some apps out there may not function properly with HW acceleration.

Ah, that works much much better. Before it seemed only a little faster than my old Kindle Fire ICS Rom, but now it's flying.

Now go and try to watch the Transformers movie you downloaded for free.... LOL

Disabling this also fixed my stuttering problems on YouTube app and 720p movies stored internally. Don't really plan on using Google movies that much anyway.

Since it's so easy to change (no reboot even required) it shouldn't be a big problem for most people. Its a very dramatic change in fluidity and silkyness you wont forget to turn it back on.
Now I just gotta figure out what's making apex redraw

As a rule anything that improves performance draws more power so I'm betting this is no exception.

Yes, there is no picture in the movie. I don't think overlays need to be turned off for speed, overlays should be supported in HW by the GPU as well. So if you force GPU 2D rendering, that is enough to really speed up the UI.
Or maybe I am wrong?

Can anyone confirm this?

It seems like disabling he overlays goes more harm than good, forcing 2d acceleration seems to be the best route.
Oh and this will use more ram, but when was the last time you ran out of ram anyways.

Funny seeing this tweak brought up here. We went through 6+ months on prime messing with that tweak. I believe it more so just enables older apps to use hardware acceleration. Most newer apps and jellybean rom in general already uses hardware acceleration in the coding by default. Regardless of what you see in developers settings. This was the case in ICS. Likely the same with jellybean also. Alot of developers chimed in on the subject that we might be seeing more of a placebo effect. It likely does work but for older coded apps n such. Most new apps should already use hardware acceleration by default(regardless of what developer setting is showing). Some apps will have issues with it though. Some apps not made to support hardware acceleration so just keep a tally of what apps act up and add them to the op. The new NVISION app for example. At first it messed up with that setting. Cut it off and the app works fine. They eventually updated the app so the setting wouldn't mess it up anymore.
It'll also raise your 2d scores in quadrant, I believe. This will drain battery faster though. I know on prime, it was hard to tell if this was really working or not. To me, it seemed to be working. But down the road I cut it off and things were just the same. So who knows..lol. I know Y nexus 7 doesn't need it. Give it a shot if you experiencing lag somewhere and see of it helps. There's a good chance though that its just a placebo effect. Thouroughly testing needs to be done with it off n on. Jellybean by default already has hardware acceleration for apps n other things. Regardless of what developers option show.

No placebo effect here, this genuinely works even in new apps especially tapatalk and rom toolbox, you should try those with the setting off and then on. Those two apps were bugging me the most. I'm sure it will drain the battery more but I already get three days of use out of this thing anyways.

Tegra 3 games really really slow?

I've been playing around with the nexus 7 for around two days now and noticed huge amounts of lag everywhere. From the menus to browsing and even gaming.
I tried Modern Combat 3 and it just stutters so bad and the frame rate drops are huge, even my galaxy s2 performed better than this.
I bought the new Batman game yesterday and that was exactly the same. In game play it lags and stutters too much to be even playable.
I have installed the latest update and even did a factory reset and it has made no difference. The thing is I watched someone playing Modern Combat 3 on the nexus 7 on YouTube and it was flawless, is there something wrong with
my unit or has the update done something?
P.S I tried Dead Trigger, Puddle THD, Dark Meadow and all are the same

I get lag on Sonic Episode 2 THD but nothing else, I thought this game was optimised for tegra 3?
Sent from my Nexus 7 using XDA Premium HD app

No lag at all on anygames. Especially tegra3 optiMized ones.
One thing I noticed though. I noticed yesterday it seemed all My games had a brief pause every few seconds. I was like wtf is going on, wasn't like that before. I started thinking something happened from me unlocking and rooting. So I look through my apps to see what could be causing it. Low and behold the force rotation app I had. I had it set to force auto rotation. So I changed it to normal auto rotation. It solved the issue. The forced auto rotation was causing issues with my games. Putting it back on normal auto rotation put everything back to normal.

YouTube playback stutter

Hi, anyone experiencing video playback occasional stuttering? I did a factory reset and its still the same :/
Sent from my LG-P880 using Tapatalk 2

Nobody having the same problem guys? It's definitely not because of my Internet connection since its really fast.
What I'm afraid of is that there's a problem with the processor or graphics chip. I've tried playing HD videos from my micro sd card and all is smooth.
Any inputs? I only have 7 days to bring this back to the shop to swap for another set and it's day 3 already :/

Don't know if this helps you at all, probably not, but I've been having alot of stuttering on youtube on my pc for the last couple of days.
Can't watch any video unless it's fully loaded, which is slow atm, and even then it stutters a bit. Might be a problem on their side.

Hello
I have exactly samme problem.
I am getting used to it even though it is annoying.

I don't really notice a difference.

What's lag?

I don't experience any lag at all from this device (and didn't on my S2 running Cyanogenmod for that matter either).

No lag to report on the Nexus 4... But interesting read nonetheless. Might use it on the Galaxy S2 (Which DOES lag, even though some say it doesn't. Compare both N4 and S2 side by side... It's painful to watch)

Is this like jet lag?

Who Lag?

More like turbo lag

No lag here on this badboy!

The lag is from the way Android was designed originally. Not all apps are even optimized for the platform and others are quick ports from other platforms. Also they are still lacking with hardware to software optimizations.

The're some apps which are lagging. But the Nexus4 itself? Bullsh**!!!

Agreed. It may be the applications that lag but not the system itself. I have yet to see a hiccup when browsing through my Nexus.

There are some pretty awful frame drops when using the device in landscape, especially in the app drawer. I wonder if this fixes that.

Don't lie.
The Nexus 4 might be the smoothest Android device, but it is still lagging compared to other systems like iOS or WP 7/8

Compared to my iPhone 4 the N4's browser is like internet explorer vs chrome.

Sounds like snake oil. Androids remaining lag is too deeply rooted to be squashed with some shell code parlor trick. Android gives content fetching more priority than rendering the UI, it's something that Google has to take care of by rewriting the framework. Ios does this beautifully btw, it doesn't need 4 cores for fluid scrolling and even with 4 cores nexus can't touch it ... yet.

Anyone ever find a resolution for this? I absolutely love this phone but I'm a hardcore user of Snapchat since everyone I talk to uses it for communication and this is ridiculous. Almost makes me want to switch phonese. Does it still work this way on CM/stock tons maybe?

i believe its just the hardware itself the sensor is trying to get more light in and it makes it lag i think (im no expert on cameras) as soon as i got a nexus 5 i noticed how much smoother everything seemed in the view finder and right now i just compared them it just seems to be the way the htc one is

Snapchat uses the camera app that comes with the phone now

Mine is occasional lag.

Same problem on mine, makes videos almost impossible with low light, my Alcatel pop s3 is extremely faster on snapshat. Is there a way to fix the problem ?
