if anyone has a problem should post device and firmware info,rooted-unrooted etc

I bet people that are facing problems on complete stock (if memory serves gokhanmoral has the new drivers in his kernel)

[Heaven Stream]

Well, mine GS3, that faces the problem, is the International, no overclock, is unrooted and runs the stock 4.1.2.

I'm also using siyahkernel but from what I know, using a stock sammy rom will trigger the old mali driver while using any AOSP based rom will trigger the newest one, from what GM said there are two mali drivers in the kernel. So sfageas should actually have the issue, no?

So I think that is more a stock rom thing, the kernel must have some optimization or element making the Mali GPU work better and avoid these problems, be it the driver or something else.

I think it is something with the stock kernel, I am using presus and no issues.
The people completely stock, can you write your Rom version for eg. XXemc3 xxemb3

damn!!im still facing graphics missing on latest revision
im play def jam when play story mode on some places i got missing head,body....in hw transform.!

You have a Sony Xperia Sola, right skyfor? Please tell us which Android and kernel version you use. Maybe someone can suggest something to upgrade your drivers.
I dont know anything about the Sony phones, but there are no glitches with my Siyah 1.9.1 kernel.

[Heaven Stream]

Well, here my GS3 is with I9300UBELL1.

slim bean 4.2.2 no issues

I got a solution for Heaven Stream and all other users of the international GS3 models. Just look at this blog post: http://rootgalaxys3iii.com/galaxy-s3-siy...s3-kernel/
This is for Jelly Bean 4.1.2 stock users and root access should not be required (I didnt need it). It contains new drivers for the Mali 400 gpu.
Read the post, think about it, and if you dont understand what it does; its likely you will brick your phone.
The easier way would be to wait until Samsung rolls out the Android 4.2.2 update.
And yes I know that not everyone knows what Im talking about here. This is on purpose.

[sfageas]

If anybody wants to try you must read read read & read until you understand every word & step by step instruction,then it will be easy
However if you do one step wrong you will end up with a nice coffee pot

yes my phone is sony xperia sola...yesterday im use ics and im still facing missing graphics...so im go back to gb but im still facing missing graphics,i dont know why...

[kevke96]

The answer is quite simple. Gelly Bean has old Mali drivers that produce these glitches.
I hope someone who has experience with the Sony phones can help you with updating them.

[Heaven Stream]

Quite of understood it, but i have not a single experience with Odin, so i prefer to think realy well before making a decision. But anyway, thanks to Kevke96 for the solution.

I have stock kernel, but I have root. I used the app Tegrak Overclock, I overclocked to 1.4Ghz. I not noted almost none diference, just more 2-3FPS on GoW. I have only really more speed when use Turbo Key on Intro of GoW Chains of Olympus, without overclock goes to 59FPS, with overclock goes to 67FPS.

Sorry my bad, bad english. Thanks.
