[Q] Galaxy S3 UI Lag with Siyah - Galaxy S III Q&A, Help & Troubleshooting

Hi All..
First lemme give my phone details:
Galaxy S3 International (i9300)
Kernel : Siyah 1.8.9
ROMs (Dual Boot)
: WanamLite v5.5 (based on ZSEMA1)
CM10.1 Nightly
MODS : JKAY framework
My problem is that there is noticeable UI lags when in the homescreen or the app drawer.
I have not overclocked/underclocked the CPU. Have no undervoltage setting as well. In STweaks, the max CPU freq is set to the stock 1400Mhz and the min CPU freq is set to the recommended 200Mhz. And I have kept the "touch boost level" to 1200Mhz.
When I see the UI lags, I used CPU spy to monitor the CPU speeds. What I could see was that the speeds were at the lower end (200 - 800 Mhz) !!! Since the touch boost level is set to 1200, shouldn't the CPU jump to 1200 Mhz when I unlock/touch the screen ? I agree that the CPU speed needn't stay at 1200Mhz after the speed boost, but shouldn't it stay at a freq to ensure that there is no UI lag ?
If the operating freq is at 1400Mhz, the UI is perfect !!! It goes to this state automatically usually (takes a while ), or manually I can make this happen by setting the min CPU freq to say 1300 MHz from STweaks. Once this state is hit, the UI wrks with no lag until say I lock the screen, or maybe the device goes to sleep for a while.
Any ideas as to why the CPU freq stays at lower values and doesn't come up enough to give a lag free UI ?

ANNNNNNNNNNNND what rom are you talking about!?! CM10.1 or Samsung? if you want a LAGG FREE phone do the following.
1: OverClock the CPU to 1.6ghz, then set min to 500mhz, use a -25mV or a -50mV
2: Set Governor to LULZACTIVEQ
3: Set MIN GPU freq to 266mhz
4: Set MAX GPU freq to 640mhz
5: Disable "gentle fair sleepers" on the CPU tab
6: Set the SCHEDULER to CFQ
7: Go to settings and enable GPU rendering
and FINALLY if non of the above work, FLASH Null_22.1 for a Samsung ROM. and Revolt, cm10.1, jellybam for a AOSP rom.
IF NON OF THAT WORK'S download super wipe and flash a new phone.

Can I just say, 1200mhz?!?! Default is 800 and I'm using 700 on my device. It's a bit extreme.
Perhaps your governor is affecting smoothness. Try using pegasusq. Or it may be the app your using to change CPU frequency doesn't even have ROOT access

No. Do not disable hardware overlays. That will, if anything, cause your device to lag more.

This is a quote from a guy over at rootzwiki
Without a hardware overlay every application that is displaying things on the screen will share video memory and will have to constantly check for collision and clipping to render a proper image, this can cost a lot of processing power. With a hardware overlay each application gets its own portion of video memory, getting rid of the need to check for collision and clipping.
Basically, using hardware overlays can reduce CPU usage by quite a bit, so I would leave it enabled.

Right.. then why dafudge is my s3 SMOOTHER with it enabled?

Maybe you're just lucky, I dunno. It's better to let a real dev share his/her input on this. I'm merely a noob who knows how to Google...

L.O.L but not that big of a noob... thanks for the info - and also reminding me for the 100,000,000,000,000 time to sign up to rootwiki

Heh, maybe not.
Uhm, you're welcome, I guess? :good:

It's probably smoother due to the fact that the CPU will be working at a higher frequency more often. Those that have disabled hardware overlays are causing their CPU to ramp up every time an application has to render an image

The lag is more obvious in the Touchwiz based Wanamlite ROM.
1) As i said, when running at 1.4Ghz (with stock voltage settings) itsef the UI is smooth. So I don't actually want to overclock. . The problem is that the CPU speed doesn't rise up and stays between 200-800 causing the lag.
2) Will try changing the governor (first let me read how it is different from pegasusq ).
3,4) Again, with stock settings itself the UI is smooth. The problem is what i have said under point 1.
5) Already done.
6) WIll try setting scheduler to CFQ (again, lemme read bout it first )
7) GPU rendering is already ticketd. Hardware overlays are not disabled (thought this would increase the lag).
Is NULL_22.1 a Touchwiz based ROM ? And Jelybam is an AOKP ROM I supose ?
Wouldn't want to do the last option.
Also, I saw that you have mentioned three ROMs in your signature. Siyah lets you dual boot right, how come 3 ? Or were you just talking about your preference ?
And, does siyah 1.8.9 for the S3 let us boot with NULL_22.1 and jellybam in dual boot? Are all these combos possible ?
Sammy + CM10.1 (this works, I knw )
Sammy + AOKP
AOKP + CM10.1

From what I understood, it just boosts upto 1200Mhz on touch and needn't stay there. Right ? The only downside there is battery life I suppose ?
Am already using pegasusq and yes, sTweaks does have root access.
