[Q] Unleash the real power of Galaxy S SGX 540 GPU - Galaxy S I9000 Q&A, Help & Troubleshooting

Hello there,
I am just curiuos if there's any way to disable VSync in SGX 540 driver? 3D applications are limited to 56FPS, so Samsung Galaxy S can't win some benchmarks, because of this ridiculous restriction. My SGS always scores about 55.7 FPS or very close to 56, but Droid X has 60 or 62 Hz refresh rate and even though it has weaker GPU (SGX 530) it can still beat SGS in some less demanding benchmarks. The SGS screen refresh rate is 56 Hz... I wish we could unleash the real power of SGX 540, which is now *STRONGLY* limited.
Maybe there are cfg files with options:
VSync=0/1
Or:
MaxRefreshRate 56 Hz etc..
Or something like that... Can somebody look at it?
Thanks in advance for answers!
Best regards,
John

While I'm sure if the framerate was unlocked it would beat every other current Android device in GPU benchmarks, in real-world use this wouldn't mean a thing since the screen itself has a refresh rate of 56Hz...so visually it would be impossible to see any difference other than screen tearing.

It's a limit to save battery, i would like to turn it off/on (for benches) but for real life 56+ fps is just waist of powerbecause of the screen that has 56Hz
(but i prefer 200fps against 60fps on my PC in my 60Hz monitor, somehow i DO notice the difference )

That's called the placebo effect. It's literally impossible for you to see it, you just 'notice' it because you're aware that the framerate is higher, so your mind convinces you that you can see the difference.

Let's try not to prove if human eye can see the difference between 56 or 200 FPS. Let's try to find out if there is a possibility to turn the VSync off to see what SGX 540 is capable of. Because it's an external GPU so it has to have any external panel control or cfg file with some options like NVIDIA and ATI GFX cards have.
Damn I wish I could see 80-100 FPS @ Neocore and GL Benchmark score that kicks ass Droid X score (which is better than SGS, because of damn screen refresh rate)... It's really possible!

About fps perception, that is discussed a lot.... dont bring it here.
The tweak -> would be nice, but just for benchmarks (showing them mine is bigger), or playing with charger connected.
This is mobile device, we got limited power resource.
On pc we got sum competitive games, they provide matchup with players around the world, and it means sth to win/lose, so ppl would do anything to do better.. But in singleplayer...on a 'phone'? No matter to me.

Mate! It doesn't matter for the power usage if there are 56 FPS or 200 FPS! GPU is doing the same job with the same power usage but is capped by VSync. It's the software (driver level) limitation, not hardware.

Why don't you just find a more graphic-intensive benchmark instead? It's pointless to turn off Vsync even if we could.

So what will you guy accomplish from getting higher scores in a synthetic benchmark which doesn't actually represent real speed?
I wish people would stop putting such an emphasis on synthetic benchmarks...

Testing purposes, to see how fast GPU really is and to kick Droid X ass. ;-) We can't say anything about the real performance of SGX 540... But we can see that every 3D test we run on SGS it gets ~56 FPS...
Mate I can ask why do people overclock their CPUs? Why do people overclock their Galaxy S CPU to 1.2 GHz? It's pointless in some way (battery usage, it's hard to see the difference without benchmark scores etc.). But for power users - people just like me - it's something to test the limits of the hardware.
I am going to check the possibility on the PowerVR forum and keep You updated.
The worst thing is that I can cool my PC hardware using liquid nitrogen but I don't really know mobile software to do the trick.

+1 to try and disable vsync! really would like to know what the gpu is really capable of...

With tables like this one, for non informed people it may look like Galaxy S is the worst of the current high end devices.

In the /system/build.prop file, there is a line called:
windowsmgr.max_events_per_sec=55
Change it to 60 and see if the framerates go up? Quadrant reports the Galaxy S screen refresh rate is 68Hz.

changed. quadrant gfx test is same 56fps max.

The config file should be somewhere in the OpenGL driver folder I think. I can't check it out because I am at work at the moment...

I changed it to 68 and although the quadrant test didnt go about 57fps, I got higher scores. JPC default got around 950 or so, with this I got about 1000.
The UI is definitely smoother though.

Interesting!;-) So we can adjust FPS on the UI right now. Looks like it's possible to make scrolling ultra smooth.

nice, please add all of the findings to post 1 , because we could find it easier later..

[Q] Quadrant Score

hey guys
ive recently flashed this kernel http://forum.xda-developers.com/showthread.php?t=975349
and im getting quadrant scores btw 1400 to 1600
is there any way to increase them
i read somewhere it can be increased by using some file named ' build.prop'
I am on Darky's 10.1 using DarkCore, and I'm getting about 1200 with EXT4 lagfixes enabled.
i used to get 1900 - 2100 back on stock froyo with OCLF 2.1
if it is only about increasing the quadrant score, you could download tegrak overclock tool from market and increase the CPU to 1.25 Ghz..
or, before that you can disable lagfix, switch to CF-root, enable all tweaks (including media stage someting), and then apply overclock and it ll hit around 2350 ...
use damians latest kernel.. quadrant scores of more than 3000 are reported(use jvp as ur firmware) hope this helps..
I just can't understand why people are so obsessed with quadrant scores??? Frankly with stock Rom with ext4 the normal score is around 1500 and with custom ROM you can get around 1700-1800 - that's it (and you can gain around 100 more by removing the journaling of the the ext4 system). Quadrant isn't reliable benchmark and people should stop striving to get higher quadrant scores.
Anyway - if you want high quadrant scores just enable stagefright if you don't mind not being able to play certain video and audio formats on your phone - at least you'll be able to brag about you scores.
quardrant scores shouldnt be an obsession..... but just merely a certain reference once in awhile....

Mods need to start closing some of these Quadrant threads, because, there are way too many.
Quadrant scores are great, if you are simply chasing a placebo (or you want the opportunity to grow your ePenis). If you want a phone which is productive though, throw the benchmark in the bin and run a blind test.
You are only testing if Quadrant is faster, not if other applications are. It is possible that optimising for Quadrant may lead to other applications being dramatically slower (because Quadrant isn't detailed enough). You will notice that the Wikipedia article is almost exclusively about the inaccuracies of benchmarking, and that developers generally don't use standard benchmarks (almost every developer will use a test suite that pops out pages of "user unfriendly garbage").
Quadrant simply doesn't provide enough information to tell you what operations is faster.
An optimisation might yield a 6x speedup of directory creation, at the cost of a 2x file writing slowdown. If quadrant is coded poorly and weighs the tests equally, it might tell you the optimisation was worth it (it will be 4x speedup overall). However, in normal usage, you might write to files 10000x more than create directories, so in the real world, it might be actually slower.
It's even less worth it considering that the time most people waste running benchmarks, and optimising their phone (sometimes they spend an hour or so), is never regained in productivity gains again.
That is just an opinion though

Okay wouldnt be a better question be whats the fastest rom?
Im still on GingerReal cause it is a combination of both a stable as a fast rom. Quadrant score of GingerReal isnt that high somewhere around 1500 - 1600. I never have forced closes and loading of files etc. go like crazy.
Tried CyanModGen and MIUI which are both great roms but they arent that stable and still have some minor known issues. I'll probably change my ROM until of one of the above have a stable rom.
What is working the best for u guys (and girls offcourse)?

GL Benchmark
CNET UK said:
To see how it stacks up against the competition, I booted up my benchmark test and hit go. On the Geekbench test, it returned a frankly astonishing score of 1,975, putting it just below the powerhouse Galaxy Note 2 and far above the S3. It did similarly well on the CF-Bench test, where it managed to achieve 13,207, again well clear of the S3.

Processor and battery: Though the Nexus 4's data speeds might not be blazingly fast, the 1.5GHz Qualcomm Snapdragon S4 Pro quad-core CPU makes its internal speed swift and smooth. Graphics-intense games like Riptide GP and Asphalt 7 played extremely well, launching and running with no stalls or hiccups. The games both displayed high frame rates with high-resolution graphics.
Because of the phone's ultrafast CPU, gameplay was crisp, smooth, and fast.
(Credit: Josh Miller/CNET)
In addition, average start time for the handset was about 23 seconds, and it took about 1.82 seconds to launch the camera. Browsing on Chrome was a lot smoother on this device than on the Optimus G for some reason. For instance, scrolling down Web pages was executed much more swiftly.

The GLbenchmarks scores look promising as you would expect. Quallcomm also has a record of drastically improving 3D performance over time with driver updates, let's hope they do the same with the Adreno 320.
Antutu however doesn't seem like it's a good way to measure the Performance of highend smartphones anymore.
The 3D and 2D scores are totally useless as the test are completely Vsync limited meaning that all new Smartphones score the same.
I also doesn't seem right that the Tegra 3 has a higher CPU score at the same clockspeed.
It's about time someone develops a decent benchmark suite for android.
This shouldn't be a surprise since the power of the Adreno 320 is mainly the SGX 543MP2 and SGX543MP4. So it has half the (GPU)power of the iPad 3, though it's sorta close to the iPhone 5(SGX543MP3). I'm actually surprised that Android phones haven't been using the SGX solution--would've been epic if the Nexus 4 had the SGX Rogue.

Did S4 advanced have a better screen than S4 ?
Out of interest, will it ACTUALLY be that much/if any faster anyway?
Would be interested if anyone with the tech knowledge could chime in....because it seems to me that the slightly faster snapdragon 805 is probably 'cancelled out' in effectiveness by the fact that the handset is now having to power a quad hd screen instead of standard 1080p.
Thoughts?
I can tell you for a fact that my gf's older macbook pro is snappier in day-to-day ui movements than my newer retina mbp which I'm guessing must be due to the added strain of those extra pixels.

There's been quite a bit of discussion in the M8 comparison thread about the impact of QHD on the LG G3. Cliff notes:
- Performance on S-801 took a pretty big hit
- Battery life took a hit
- Display contrast, black levels, and reflectivity all took hits
S-805 isn't a minor upgrade. It and Adreno 440 should allow QHD to perform as well and most likely better than S-801/1080P. So battery life and the quality of Samsung's QHD display are questions left to answer. The M8 thread also has discussion on the value of going from 1080P to QHD which is really pretty limited.

Performance isn't 'canceled out' since the 805 can handle Ultra HD (4K) screens. The following scteenshot is from Qualcomm's site which summarizes the specs of both the 801 and 805. Snapdragon 805 breakdown

However, QHD content is currently limited to whatever bloat comes pre-installed from Samsung and wallpapers you can find online . As a result, people can't yet take full advantage of of that high res screen until app developers update their apps and there are very little YouTube videos above 1080p.
3GB RAM vs 2GB in the S5.
Great Samsung. Great.
That phone is a beast. But so is the regular galaxy S5. I don't think ppl should be upset really, its business. If you enjoy your phone then just enjoy it.

There will be little or no QHD (2K) native content. Commercial content will be 1080p or UHD (4K). That means it'll be up and down scaled which impacts image quality. QHD is a marketing ploy of questionable value. Lots of reasons supporting this in the M8 comparison thread.
This is indeed a good read regarding Snapdragon 805's cpu and gpu power.
http://www.anandtech.com/show/8035/qualcomm-snapdragon-805-performance-preview
From there I got couple important points:
The 805 can handle a QuadHD resolution device at the same frame rate and with same performance that an 801 can drive a 1080p device.
It is said to use 20% less power and provide 40% more performance compared to an 800 SoC
The 805 has small (comparatively) cpu boost and significant gpu and video engines boost.
The GPU tests were there. It nailed pretty much everything.
The 805 has HEVC HW decoder, but no HEVC HW Acceleration until the 810 SoC comes out in H1 2015.
I personally did not know what HEVC was. It is actually H.265 codec that provides magnificent video output at much lower bitrate than ax264/h.264 encoded video.
I curiously downloaded Big Buck Bunny 1080p encoded with HEVC that sized only 130 MB. The h.264/x264 encoded video was available at the Big Buck Bunny's official website to download which was roughly 700 MB. The 130 MB file indeed provided great output compared to its regular 700MB variant!
The only thing I´d like in my S5 is 3GB ram. I do not want a QHD display which will only drain extra battery without me even being able to tell the difference.

Why would you like 3gb of ram? Have you ever run out of it on your S5?

Yeah alot of times, many apps have to reload when multitasking, it´s clearly not as good at multitasking as the note3 for instance.

So true. Someone above wants S-805 because it's "faster." Faster at what? 85% of apps don't use more than two cores according to Qualcomm. Screen transitions and app openings certainly don't need S-805. In every upgrade cycle (720p/S-600<>1080p/S-800<>QHD/S-805) the potentially huge gains in performance and battery life ended up minor because of the resources consumed by the display. Let's see some benchmarks from the SGS5 LTE-A before everyone wets themselves over it. Display quality took a big hit on the LG G3. Let's see how Samsung does.

Yeah, that's exactly why I asked. I don't think people understand how ram works, they just want more because it sounds good.
Unused ram is exactly that, unused ram. No matter how many apps I've had open at once, I've never reached near 2gb of usage.

That´s because the phone hibernates apps before it ever reaches full RAM usage. More RAM = more open apps which allows for faster multitasking. You´d think this was basic knowledge by now.
I´m sure you all have switched to an open app only to have it reload like it was first opened.
Coming from an iPhone with 1GB of ram I am overly aware of this issue.
And no I do not want the new S5, I just wish Samsung had put 3gb in the S5 in the first place, like they did in the note3.

Going to use 1080p on this device for a few days

I'm going to downscale the device resolution to 1080p for a few days if the 2K screen really affects the battery that bad.. If you want to do this, download Resolution Changer from Google Play, and set the screen res to 1080x1920 480 dpi, apply and reboot (important to reboot, if not, the UI will be messed up)
Going to edit this in 3 days. Cheers!
Unless you only use up exactly 1920x1080 pixels on the screen battery life is not going to change much.
Right now that resolution just causes the screen to upscale so the only battery savings would be from the gpu working less driving a lower resolution. The screen which is the main batt hog will still be drawing power as per normal.
Unless you are 3D gaming at 2K then there will be little savings if any. 2D is pretty easy to render at 2K Resolution. And the GPU is probably optimized for 2K and NOT 1080p. So you might actually see a performance decrease running lower resolutions like the old days of Voodoo2 GPU on PC. I dont know... benchmark it and see.

unfortunately, this is the correct response. even though the human eye cannot spot the difference between 2K and 1080p if the screen isn't right on your eyes (there have been several articles about it on XDA portal..interesting reading), lowering the resolution on this device is useless as your phone will power the extra pixles(they are still there) but the GPU just won't process them.
2K was and will be a marking gimmik to sell more phones. just like 64 bit.
hopefully we'll see a 5.5' flagship this year with 1080p- same view as 2K on 5.5' screens and with 6+ SOT easily.

That is correct, but there's one more thing:
the GPU won't work less. Whatever power is saved not having to draw the full size of the screen, will be spent upscalling the 1920x1080 image to 2560x1440. I bet that this upscalling can draw even more power from the battery than simply let it work on its native resolution.
So, if your intention is to save power, reducing the resolution is a bad idea, and it is totally useless.
The only reason to lower the resolution is if you have eyesight problems.

''Thankfully, the battery isn't as persnickety as the rest of the phone: It typically managed about 13 hours on a single charge, all while I was futzing around in HipChat and Hangouts, firing off emails from CloudMagic and playing the occasional documentary in the background on YouTube. When it came time for our standard video-rundown test (all together now: looping a 720p video with screen brightness set to 50 percent), the new G Flex held out for ten hours and 13 minutes before needing a top-up. As it turns out, the charger's no slouch either; it takes the phone from 0 to 50 percent in about an hour, and it'll top off the battery completely in less than an hour after that.''

I'm reading mixed reviews about the LG F Flex 2. however all in all I don't think 10 SOT at 50% brightness is less than amazing (they didn't put a chart showing comparisons to other phones, but personally I don't get more then 5.5 SOT on the note 4 no matter what)

Personal usages are subjective and I don't care about them.
It is not 10hours of SOT in normal usage, it was a test.
In GSMarena where they do pretty well battery Test comparisons, they show a mediocre scores from what you should have expected.
At The same standard-test, Engadget says that Note 4 get 13h.
But 50% brightness on Note 4 is two times higher (291nits) than on the GFlex 2 (152nits).
So results are pretty poor on the Gflex 2 considering the fact that both have the same max brightness.

And you also have to take in mind pentile matrix. A RGB panel with the same resolution looks more shaper.

My N910F scored lower in 1080p then it did in 2k.
The highest score is default resolution.

[ 8 cores - They all work? And how they work? ] ???

Hi!
So, i found how the 8 cores from the P8 Lite works!
First of all, based on the Cortex-A53 the octa-core 64-bit Kirin 620 processor was made to supports HDR photography, and 1080p HD video encoding and decoding. The chipset also supports ultra-fast LTE Cat4 with downlink speeds up to 150Mbps. The performance can be comparable to Qualcomm’s Snapdragon 410.

So, how it works in phone?
I installed the app System2 and stay for a will observing the cpus and is like this, the first block of 4 cores are linked and have for objective the first ground apps, the ones that are running "in first plan", the second block of 4 cores are for background apps and functions like for example installing a app, in the image below i was updating from Google Play you can see the first block of 4 cores almost sleeping and the second block of cores almost at 100.
You can confirm this by the graphics color.
So, like this in a benchmark the scores are from the first block of 4 cores, and the phone release them from the not so important apps and put them in the second block of a 4 cores.
Like this, first block of 4 cores are masters, second block of 4 cores are slaves!
The kernel specifies what each core does.
Will this helps in improvement? I think so, but not a hudge one.
This explains why Benchmark apps give the same scores then a 4 cores CPU, they are only using the first block of 4 cores ...

I don't get how does it save power or does anything else good for this device processor to work only 4 cores at time, when all 8 cores are similiar to each others. Maybe I read a bit hastly but I only find stuff about how it helps power saving if all cores aren't the same.

Do you need to do something to make it show all cores? It's only showing 4 cores online for me.
just my 2p:
Set battery to smart (hope it's the english version), then use asphalt 8 (or other heavy app)
Set battery to performance, then use asphalt 8 (or other heavy app)
You can see a lot of difference.
Set battery to smart (hope it's the english version), check battery percentage, then use as always your phone, after 1 hour check battery percentage again
Set battery to performance, check battery percentage, then use as always your phone, after 1 hour check battery percentage again
Use Antutu and when testing cpu, look at system panel 2 and you will see all the cores working at 100% In this capture is not 100% but I have managed to work at 100%
It has to be a stock rom or it has not changed the kernel, most of the custom rom has a bug in the kernel and the cpu does not work well.

Plus you can "unlock" the mhz, you can have constant 1200MHz by deleting/renaming something... Kernel Adiutor doesn't really help...
