i use this build.prop tweak from fluid engine

debug.egl.swapinterval=0

but i personally dont use this for daily use because there are lot of screen tearing

#sorry for bad english :D
[Nexus 4 General] morfic:
Did he say he didn't do it in kernel?

There are others who can build a kernel from source ;)
[Nexus 4 General] simms22:
the screen tearing is why kernel devs dont do it. Trinity did it for several weeks on the n7 and on the ns, some reported tearing, others didnt. but there really wasnt any gain for users, so it was stopped. anyways, this is still good info, even for info sakes. thank you :)
[Nexus 4 General] nomancoolboy:
Thats mind blowing dude ...

Its gone faster than the HTC one ...
[Nexus 4 General] thevizier:
no problem sir :D
[Nexus 4 General] simms22:
the difference was that trinity changed the panel frequency, kernel side. anyways, im not getting screen tearing right now. havent played any real games yet though. heres a fun quadrant, got 157fps going up the stairs at 1728/1728.. :)
[Nexus 4 General] thevizier:
will this be on the next kernel build?
[Nexus 4 General] simms22:
no.

this is something for the user to decide to use, not for the kernel.

[Nexus 4 General] bixano:
How do you did this ??? tell us !! :fingers-crossed:

It works only with the build prop tweak ?
[Nexus 4 General] thevizier:
well... just try it yourself ;)
[Nexus 4 General] simms22:
thats all, the build.prop edit. itll raise graphic scores.
[Nexus 4 General] atxbang56:
and how to ?

BANGed from my Pretty CoOl Nexus 4
[Nexus 4 General] simms22:
copy/paste that line posted into /system/build.prop/with a root file explorer, save it, then reboot for it to take affect. make a nandroid backup first, just in case :)

---------- Post added at 11:34 AM ---------- Previous post was at 11:26 AM ----------

debug.egl.swapinterval=0

copy/paste this line into /system/build.prop/then reboot for it to take affect.
[Nexus 4 General] myturbo1:
So Is it actually performing better. Or just making the benchmark think it is ?

★Nexus⁴★PA3.95★LTE★
[Nexus 4 General] simms22:
more fps during 3D graphics. better is relative. for some the actual graphics will be worse(tearing), for others itll be better(no or very little tearing). itll depend on your device. but, fps will increase regardless.
[Nexus 4 General] kszaq:
If you don't want to play with editing build.prop every time you flash a new ROM or don't want to edit it at all, you can also enter this in terminal:

echo debug.egl.swapinterval=0 >> /data/local.prop

and then reboot your phone. If you want to bring back the fps limit, simply delete /data/local.prop file.

Personally I don't use my phone with no fps limit due to increased battery drain (more fps => higher GPU load => higher battery drain) and it does cause a lot of screen tearing, especially when scrolling fast through ListViews.

I am using the latest 4.3 raabeanjelly and trinity kernel with min and max 1.7GHz with fsync and temp throttle off. Other setting follows the trinity default. However I am just getting at most 6000 in quardrant which is quite different to simms 10000 quardrant scores lol

Even if i change other kernel or even the stock kernel, my quardrant lies between 5500-6000 which is so strange. Anyone know the reason?:confused:

Can someone explain why moto X 2 core phone has 84xx in quadrant benchmark, but my nexus4 is just 6k? It's because of 1.7ghz clock speeds?
[Nexus 4 General] DEV_Geek:
Cool!

Can you please give me the link to the ROM and the patch you are using? Thanks in advance;)

P.S. Awesome score!
[Nexus 4 General] simms22:
yup, need the patch. and its noticeably faster, without running benchmarks.
[Nexus 4 General] gskillivenom:
I tried the patch that was linked above , on quadrant I got 7830 , which is a massive improvment over what i was getting before ( maybe 5000 ) , but Antutu force closes for me when I run the benchmark , of course not saying this is a problem for me , just wondering why does that happen?
[Nexus 4 General] -JFK-:
Hello,

You are probably OC and your phone is too hot, that's why Antutu FC.

Let it cool down and retry (sometime we need to cool it down under 5°C to make it run at high OC like 1.7 and 1.8GHz)
[Nexus 4 General] gskillivenom:
Im running the Matr1x kernel , which doesent support CPU OC , and i didnt OC the GPU either. So its not because of the temps.
[Nexus 4 General] sub1287:
No it is still most likely temp related its a picky benching app.
[Nexus 4 General] simms22:
you dont need to oc to hit the throtyle temps(if you dont disable them). i can easily hit tgem at 1026mhz too. but i disable all the different throttles.
[Nexus 4 General] gskillivenom:
Throttling is on , and I tried waiting for it to cool down , but still it force closed . Tried reinstalling , didnt help , cleared dalvik cache and cache , still force closes. Not an issue for me , but kind of strange , still Im happy with the way better quadrant scores.
[Nexus 4 General] simms22:
it is strange. i also had one day last week when antitu would close. i deleted the antutu app data, and antutus storage folder, and hasnt given me problems since.
[Nexus 4 General] gskillivenom:
That seemed to work . Thanks
[Nexus 4 General] simms22:
it was probably a corrupt file in that folder

[Nexus 4 General] TheNerd:]:
Would I need the patch if I had cm10.2
[Nexus 4 General] meangreenie:
Depends on wether cm10.2 uses ...

1) krait CPU library enhancements (it must likely does, check antutu for @ 2100 score at stock speeds)

2) gs4 dalvik libraries (probably/definately doesn't, but it may use different dalvik enhancements, a quadrant run at stock speeds will show where it's at)

And of course it all depends wether you want the above mentioned enhancements too.
[Nexus 4 General] Dark Fear:
hi dude.. can you explain a bit more clear?

you mean , you yourself don't know exactly whether cm10.2 uses 1 or 2?

does these patches really improve performance (in real life.. not only benchmarks)

and i hear they might cause some issues.. is it right?
[Nexus 4 General] kszaq:
CyanogenMod 10.2 (and 10.1, too) uses CodeAurora's bionic improvements and some more, therefore it is superior to S4's bionic library.

They don't use dalvik enhancements that are used in libs from S4 ROM as these are proprietary closed-source things that we don't have a source code for. In contrast, they have merged STE's patches that improve Dalvik VM performance but not as much as Qualcomm's proprietary extensions do.

The issues people were mentioning in this thread were related to JSS15J and not the library itself. You can flash the library on both JWR66V and JSS15J ROMs.
[Nexus 4 General] ctfrommn:
So would it be a good idea to only use the Dalvik portion of this and which are those? Just the dexopt file or some of the libs too? Im using a CM bionic fork with many commits on top of it so it sounds like I wouldnt need that.
[Nexus 4 General] sub1287:
Just flash em and find out, there is a revert zip after all. ;)

They make a noticeable difference on my setup with RasBean and trinity.
[Nexus 4 General] zephiK:
Seems like the patches are causing Nfc and Phone to fc upon boot on crDroid which is using CM10.2 commits. Anyone flashed a recent version of CM10.2 and have the same?

Used to work just fine.
[Nexus 4 General] simms22:
you dont need the patches for cm10.2, if they added the commits that include anything similar to the patches. if youre getting 20000-22000 in antutu without the patches at 1512mhz, then the rom includes them.
[Nexus 4 General] zephiK:
hm but quadrant scores dropped significantly >_> ill do a quick antutu and see what happens in a few

edit: only 14k... 1.5 - 1.5, gpu rendering on

[Nexus 4 General] way2muchcoff:
I have been ready to ditch 4.3 and go back to 4.2.2... but not yet.

I was routinely able to get 23000+ on Antutu with Xylon/Franco/4.2.2

On 4.3 I haven't seen higher than 17,100 (and that was only once.

I am on odexed stock. I've tried the following kernels: faux/franco/stock/semaphore. Now I am about to try the latest Trinity.

Question.. Can I use the kszaq's dalvik+krait patch with stock, odexed, jwr factory image?

My guess is no... but I thought I would ask :)

Update: with oc trinity kernel i get 18500 antutu, and 6159 quadrant... no patch. not great but improved a bit....
[Nexus 4 General] Ace42:
I think this is caused by having so much firepower in a confined area. Even though the chips are 28nm it looks like they still run the risk of overheating. Although it's possible that the GPU is overheating since some of the graphical tests are lower than the competition--I think Adrenos use something called Clock-Gating to restrict frequencies.

[Nexus 4 General] Monkeybrew:
Relevant comment from Pipperox: http://www.anandtech.com/show/6425/google-nexus-4-and-nexus-10-review?all=true

First off: i do not support any product.

Second: It's not that I didn't want to hear about the iPad 4 performance, i just hadn't seen any review out at the time i was writing. Now i did.

Third: you're free to believe whoever you want, but I do not need to believe to Anand, although i generally consider it a reputable site. As a computer engineer with enough specific knowledge on such matters, i believe i understand enough to form my own opinion.

Benchmarks for mobile phones and tablets are in the stone age.

Several "reputable" tech websites have been posting Quadrant scores for years to compare phones performance.

Should I believe those?

I've personally witnessed Quadrant scores being increased by factor 2.5x on the SAME DEVICE, with minor tweaks on a custom rom.

Tweaks which did not yield ANY tangible improvement in any other application.

Browser based benchmarks: well they're just that, BROWSER benchmarks.

On my device if I test 3 different browsers, i get Sunspider and Browsermark scores which range anything between 50% and 100% (the latter being the "fastest" browser).

Chrome is NOT the fastest browser, btw.

GLBenchmark: out of all those tests, only 2 actually render a game like scene. Those are Egypt HD and Classic. Then these are divide between "normal" and Offscreen scores.

Only Offscreen scores are run at the same resolution on all devices, so they're the only ones which can be used to compare GPU performance.

Bit IF you want to compare *per DEVICE* framerates, then off course resolution is relevant and you should look at the "on screen" scores.

Finally the other tests from GLBenchmark like Fillrate and Triangle throughput: when you want to buy a PC graphic card, do you base your purchase on 3DMark scores, or on a dozen GAMES average fps scores, games which the *reputable* tech sites update on a yearly basis?

The PC industry has moved on from synthetic benchmarks.. 10 to 15 years ago.

Before we had things like, NVidia's Riva 128 beating 3Dfx in synthetic benchmarks, and then people scratching their head when their games were not running as smoothly as on their friends' 3DFx.

Fourth: a quad core Snapdragon Pro, running more slowly than its dual core sibling (which has also a lesser GPU), and slower than its IDENTICAL TWIN sold under another name (LG), doesn't sound right to me and makes me think that there were issues during the test (either of HW, SW or methodology nature).

But you're free to believe what you want.
[Nexus 4 General] Lownita:

Everyone interested in the Nexus 4 needs to read this!!!

http://arstechnica.com/gadgets/2012/10/need-for-speed-just-how-fast-is-googles-new-nexus-4/

Check the optimus G results as its the same specs, but running ICS

it shows the performance of the s4 pro and what it should do once software is fixed on the pre-release stuff that reviewers have.

And if it can do that on ICS .... It should be better, not worse on JB overall.
[Nexus 4 General] jader13254:
Hope google fix that and android 4.2 is really the fastest android ever so finally a device which is faster than iPhone 4s ;) or 5 :D

2GB RAM i exspect to play MC3, MC4 and MC2 all together and no lag superb crisp MC2 (best online) no touscreenn bug as my arc S on ICS... Finally i can win vs iPad cheaters ;)
[Nexus 4 General] Ace42:
Since Jelly Bean has project Butter shouldn't it be much quicker...? And it looks like the iPhone 5 continues to mop the floor of Android devices. The Apple chips always seem to be ahead of the Android chipsets no matter how high of a frequency they use. :/
[Nexus 4 General] chrisjcks:
Well, it shows it trades blows with the A6 GPU in the iPhone 5, and if it can do this on ICS ..... It should run fooking sweet on jelly bean 4.2 lol

I've no doubt the cpu bests the iPhone, browser benchmarks are never a good indication, in head to heads - I guarantee the nexus will be faster.

Even reviewers of the pre release stuff have all stated its the fastest phone they have used.

But what it clearly shows, is it destroys our own top end phones which are wayyyy more expensive.
[Nexus 4 General] jader13254:
I really wanted to get this Phone. Cheap & Fast. But LG.. Ok LG is fail... Let's see!

Now first i thought: perfect phone, but now:

- Throttling Issues

- No Remove-able Battery

- Low Build Quality & Hardware-Brick Issues

- Just 16GB, why not 8GB & MicroSD, please?!

- xda news about Quality of LG ( http://xdaforums.com/showthread.php?t=1973171)

[Nexus 4 General] renna1992:
you know that all these tests are done with prerelease software and maybe not even final hardware, right?
[Nexus 4 General] Ace42:
True, but Google/LG were dumb enough to allow professional reviewers give their take on said device. You can't blame everyone for not *knowing* that these were pre-release devices--not to mention that potential buyers reading those articles will not know either.
[Nexus 4 General] jader13254:
Because i still wait for a review with final release.

Sure, Hardware change 10 days before release... Haha ;)

Software is definitely not final, true, thats not new, but that can not fix all issues.

And FYI:

I know those are prerelease phones (since this device isnt released lolz)

But software can't fix all issues.

I'm really impatiently waiting to see a review after the release...
[Nexus 4 General] yahyoh:

IMEII on the back is really annyoing since you cant replace it if your device is cracked on the back.

[Nexus 4 General] Venekor:
After the Optimus G not being able to finish the benchmarks and crashing due to hardware issues, it is clear this has been hardware throttled back. I'm sorry but Android 4.1 - 4.2 just doesn't make this much different, a new browser might suggest poor performance and battery issues, however it doesn't explain why it is so down on power for its specs.

It has been throttled back due to issues the Optimus G has.

Shame...

I will Defo wait till next year for the GS4.
[Nexus 4 General] simms22:
you can use the patch. grab the revert just in case. the reason you saw higher scores on 4.2.2 than 4.3 is that those 4.2.2 roms all had something very similar to these patches already included. some 4.3 roms have started including it again. some aosp roms and stock dont include it(aosp roms just not yet). try this zip, if nothing then use the revert zip. to be on the even safer side, make a nandroid backup in your recovery.
[Nexus 4 General] way2muchcoff:
Gave it a try.

I couldn't get past the google x during boot. I used the revert patch and it booted fine. I tried twice and got the same result = no boot. No problem. I am ready to try a new rom anyway, maybe rasbeanjelly or psx. :)

One more quick question... can i edit the build.prop to disable the 60 fps limit on stock/odexed? Sorry for the noob questions. :)
[Nexus 4 General] sub1287:
RasBean is great!
[Nexus 4 General] simms22:
you can always try. i stopped using the edit. it was fun for a couple days though.

btw, rasbean doesnt include the dalvik and bionic stuff yet, but the patch works :)
[Nexus 4 General] way2muchcoff:
Thanks guys... Appreciate the responses. :)

I have been shy to post at xda, don't know why. But I'm a bit of a flashing and benchmark junkie. Funny i didn't really look at this thread until a couple of days ago. :)
[Nexus 4 General] simms22:
i was shy to post on xda as well, even read xda for almost 2 years before i joined. now i cant stop posting :p

anyways, welcome to our thread :)
[Nexus 4 General] way2muchcoff:
Just to summarize my findings...

Stock/Odexed/JWR Rom

Trinity Kernel - CPU/GPU OC

1) Krait/Dalvik Patch causes no boot

2) 60 fps limit disable build.prop edit doesn't work with local.prop created by terminal editor

3) 60 fps limit disable works with direct edit of build.prop

Best results:

Antutu: 20387

Quadrant: 6286

Maybe this info can help other guys using stock rom. At least i can get over 20000 on stock!!!!

Will move to Rasbean now...
[Nexus 4 General] TheNerd:]:
Will they ever be included
[Nexus 4 General] simms22:
i dont know, only rascarlo can answer that. i can be convincing sometimes though :)
[Nexus 4 General] kszaq:
As I stated in the post from which you can download the patch: dalvik library from S4 won't work in odexed ROMs.

If you want to score a bit higher in AnTuTu, you can delete the following files from the zip: libdvm.so, libqc-opt.so and dexopt. This way you'll get a flashable bionic patch for odexed stock ROM. You can also try replacing the files in the zip with libraries from a CM 10.2 nightly. This should work fine on stock odexed ROM and should give you both AnTuTu and Quadrant score boost.
[Nexus 4 General] simms22:
its my fault, i told him that he can always try, and restore if it doesnt work :p
[Nexus 4 General] sub1287:
That's always my attitude. There just isn't enough of that ol crack flashin' spirit anymore.

Flash now, fix later. ;)
[Nexus 4 General] way2muchcoff:
Rasbeanjelly 4.3 (latest), Trinity Kernel (latest)

Krait/Dalvik Patch, 60 fps limit removed

Highest scores i've seen on my phone!!

Quadrant: 8963

Antutu: 24963

Thanks guys. Most appreciated. I suppose i'll fix the build.prop back as the graphics aren't great with this set... as many folks have mentioned.

Just another question. Anyone know what causes the RLOD with Antutu benchmarks? It's happened to me a bunch of times. No big deal to remove the back and unplug the battery. Fixes it every time. The back cover is busted already already... you can guess why. :angel:

But the bumper holds it together nicely... :D

Hmmm.... I posted images but they were HUGE... seemed greedy so i deleted them...
[Nexus 4 General] simms22:
from wat ive seen, rlod is caused by the phone thinking that the battery went to 0% or under. you dont see it reported as often as it used to be reported. i think its a quality control issue from lg, because it happens, or used to happen, to stock phones too, at stock speeds. as many times as ive crashed at 1836mhz, and with antutu, my phone has never seen rlod.
[Nexus 4 General] way2muchcoff:
That is interesting. I've had maybe 12 RLOD's. All but one of them came when benchmarking with Antutu. Different roms, kernels, versions of android...

I don't have the foggiest... (scratches head... :confused:)

At least they are relatively simple to correct them...

^^^something odd with that antutu 2d score? Isn't it usually about 1,600?^^^
[Nexus 4 General] michelD:
This high 2D score is due to the build.prop patch that breaks the 60fps limit.

See few pages back.

The problem is that this patch introduce a lot of artefacts: so not useable for daily usage.

Ok, time to clear some stuff up. Unless specifically stated in a lcd display's specifications, and it was made in the last few years, it only supports up to a 60hz refresh rate. No matter what you do, you can't make it refresh faster. You'll just get screen tearing and your GPU will consume more electricity and generate more heat. This isn't a cathode ray tube display with adjustable refresh rate. Only for Benchmark! :p

Simms, have you reproduce the 10000 at Quadrant?

Impossible for me to get more than 9300...
[Nexus 4 General] simms22:
you need 1836mhz to make 10000 possible. right now 1836mhz on trinity has issues, so its capped at 1726(for now, until it gets resolved).
