[JB] GPU Memory

Hey guys,
I havent flashed Jelly Bean yet but I think i know why for example Temple Run 2 lags.
The GPU has not enough RAM allocated.
At GB the GPU has around 200 of RAM
At JB it has only around 100.
Anybody know how to change it?

Even if u play 720P video, it lags and sometimes freezes I experienced that.

I think you are mistaken. This is not a windows based OS. Free RAM is useless RAM.

Well I ws quite sure abt this lag on my phone, that is why I posted it. I tried playing many videos with stock video player, and everytime thr ws a lag.
But I ll try It with mx player as well.

I just use stock and I didn't see any lags maybe it's something else...

200MB of RAM allocated to the GPU? That's impossible, on GB we had 555MB of usable RAM, 213MB was hardware reserved, some of this was allocated to the camera, some for HD 720p playback and a tiny amount for the GPU itself, the specific amount to be allocated is kernel dependent. You can't do anything about that. The change to kernel 3.0 brought several changes, the whole Mali libs were reworked and newer modules were used, that should bring better performance in theory.
The reason behind the lags in Temple Run 2 may be either hardware acceleration (which may not be working as it should) or a GPU lib issue. Both shall be fixed in the final firmware. You can't just expect things to work right away in such an experimental firmware which wasn't even meant to be used on a daily basis.

yes, basically it is not for end user, this is just experimental rom so we can find what's inside the rom (feature etc) and find some bug if exist.

Ever thought that this "leak" brings Samsung free testing? In a relatively short amount of time people found some bugs with battery drain and BT issues.
It could be a premeditated release to help developers build a bug free firmware sooner.
Next step would be to make the source code public and then they would get help with code generation as well
Just a theory, don't want to start any flames

To any of you who might have concerns, there is no doubt about it -- performance is lower on JB at this point, but hell...
IT'S NOT GPU RELATED.
The issues you've been reporting directly address video decoding issue and/or lower CPU performance in some scenarios.
GPU does not take care of video encoding/decoding. My guess is there is still no full HW accelerated decoding available.
On a side note, vRAM is irrelevant to GPU performance as well. vRAM keeps pre-rendered frames and texture data. How does that quantity make GPU faster or slower? If there was not enough vRAM to handle all the texture data and pre-rendered frames - you'd see artifacts on the screen, yet you don't.

Bad graphics on games

I've been trying some games on my GT p3110 and I've noticed the graphics are pretty weak compared to other devices', games such as The Dark Knight Rises, MC4 and others. I'm uploading some printscreens of Blitz Brigade I took while playing. Check out the outlines of the shapes..Are your graphics better than this or it's normal on this device?

Our tab isn't the best option for games... maybe its normal for our tab.
the Nexus 7 with Tegra 3 is the best gamer tab!

First of all post high res pics .
And secondly i have tried many games(almost all good ones)
I don't see any graphics issue leaving games like real racing 3 which set graphics intensity according to devices(which can be set to high with some patches after which it too works great).

Some games allow me to increase or decrease the graphics quality.But, on Dungeon Hunter 4, for example, my only choices are Low and Very Low quality... why is that?

I guess they read the device specifications and automatically they include only resolutions that the device would run

hey ur pics arent normal i play blitz brigade on my tab 2 p3113 and its better than that

But if they choose the graphical options automatically, why our devices run the same games at differently? Also, when I was playing Dungeon Hunter I could only switch between very low graphics and low graphics....why can't I choose better graphics?

U shud knw that the tab 2 isnt the perfect tablet it is faulty in many ways they said it had hdmi but no it doesnt plus its cheap overall it isnt tegra so u shud be satisfied by what u get for such a price it is a good bargain . Sry not helping u but dont try to mess with files or using apps that spoof ur device identity I tried and had tab was soft bricked

U can probably do something similar with other games!
Sent from my MT11i using xda premium

If you run custom ROMs like CyanogenMod or flash a custom kernel such as KK, you realise that most graphic issues are resolved. The problem lies mostly with the outdated/poor implementation of PowerVR drivers in Samsung's stock ROM. Custom ROMs & kernels are using newer drivers.

HM I tried to do that with the game in example (Real Racing 3) and it worked but I don't see how to do that with other games

There's some patching tool for Modern Combat 4 that can tweak the graphics if I recall. I think you can check in the HTC One X forum.
But that's beside the point, the main point being that the PowerVR SGX540 GPU is starting to feel a little underpowered as it shows its age. Even if you could force the games to run on high or max settings, performance would take a big hit, in some cases, the game slows to an unplayable pace.
The reason why there are patches, tools & mods to manually tweak graphics settings is because of the fragmented nature of Android, some devices have powerful hardware but have not been properly supported by the game developer yet.
---------- Post added at 04:45 PM ---------- Previous post was at 04:41 PM ----------
By the way, I have checked out the screenshots in this thread, they seem fine?
I would recommend the threadstarter to check out these games on other PowerVR SGX540 devices for a better comparison. If these games look better on other PowerVR SGX540 devices, then it would warrant further investigation.
As I mentioned already, the stock Samsung firmware for P31xx uses older PowerVR drivers according to various modders. By switching to custom ROMs or kernels that implement newer PowerVR drivers, users have reported better graphic performance/compatibility in games.

Well i had bad graphics with brotherhood of violence
I had installed brotherhood of violence game and was surprised to see the difference in graphics between s2 and tab2 for the same game. Graphics were soo terrible that i had tp uninstall the game from my tab and had to play on s2....
Well one possibility to have better graphics is to overclock the gpu(more computations per second) and then use patches for higher settings in games... as previously mentioned in the thread some developers ( mainly gameloff) seriously cap the performance...
u can use any custom kernel like kk's blackhawk/next kernel or dhollem kernel to overclock the GPU... see their respective threads for more info..
Our tabs GPU is clocked at 304mHz by default in stick and cm... these kernels allow overclocking 384mHz and 512mHz..
so the problem of frame rate drops when using patches can be solved by overclocking the GPU...
But we need to remember that Powervr540 is at least 4 yr old technology( i first saw it in galaxy s)... so we need to cut it some slack...
Cheers

[Trick] Lower Minimum Brightness a lot !!

The minimum brightness is still very bright in my XL .....at night i ve to use night filter, a kind of app that puts a black colour filter over screen.....
This lowers the contrast and screen looks washed out .
I found a fix in Gravity box......i managed to lower the brightness to a lot lower level.....now i dont even use night mode filters....screen has good contrast at night too and my eyes are not strained anymore ......this likely improves battery life too .
Steps :
1. Install Xposed .....set it up
2. Download Gravity box module .
3. Under the Display tweaks and go to brightness settings
4 . Set minimum brightness level to 5 as shown in the screenshot .
5. Reboot
Enjoy

@sherry_94 a nice and informative post but we can also do a soft reboot also and also you can use Pie controls with this app :good:

Or u can use screenfilter in Play Store without installing Xposed n have a rooted Xperia L

I too use screen filter but as he said it lowers contrast ratio too, and this tweak will save battery too thus more useful

Can you do something similar to this, but with the volume, and instead of reducing the high-volume limit, increase it?

Sorry , i cant do anything in this regard.
But in my Xperia Tipo , the volume level was higher in cm10 with DSP Manager compared to Sony stock rom with xLoud.
So, dont lose ur hopes until cm11 arrives .

higher gamin performance and full graphics nova 3

Hi Here i show the easy way to enable nova 3 full effects without using the navbar in the Galaxy s4
You need rooted device,
Resolution changer from playstore
Set screen resolution to 540x960 and dpi to 220 apply and enjoy
You will notice that the screen ist AS sharp AS before.
Now you will notice that games run smoother

Why is the grafics sharper at lower resolution?
It cant be sharper then fullhd or?

I don't think we should change resolution to have the games run at full speed as they should on such a high end device...
