Quick question guys, which governor is best for pure gaming

I would've tested this myself but there's just too damn many of them :p

Also I heard the msm-dvcs governor is best for gaming on the HTC One but anytime I try and switch to that it instantly crashes . Does everyone else face the same? And yeah which ones the best for gaming :)

Do you think we'll get even more performance with new gpu governors? (I'm waiting for a ktoonzervative gpu governor ;D )

Gesendet von meinem GT-I9505 mit Tapatalk 2
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
GPU governors are pretty useless (given that you cant control cores, only GPU as a whole), there is nothing to really tweak on them except a touch booster. At some point I will give faux's simple governor a try and make sure it scales properly from 100-720 (or whatever is choosen) and if that goes ok, I will add it permanent and enable my GPU booster in ktoonservativeq :D :good:
[Galaxy S 4 i9505 Original Android Development] iamnotkurtcobain:
720 lol ;). Gpu voltage control will be awesome too.

Do you think gpu frequency of 545+ mhz is noticeable on ui? (Don't play that many games).

Hope Android 4.3 brings some gpu/performance improvements.

Gesendet von meinem GT-I9505 mit Tapatalk 2
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
I dont really think 545 helps for just android UI, just gaming. 720 might help though for UI since it is such a huge jump and GPU seems to love that speed.

I've installed the kernel and applied these settings in KTweaker app,

General

Min: 189

Max: 1674

I/O Scheduler: row

CPU Governor: ktoonservativeq

Governor Adjustments: All default settings

Extras

Screen Off Profile MHz: 594

Screen Off MHz Call: Enable

Screen Off Profile Sched: noop

Screen Off GPU Max MHz: 200

GPU Max MHz: 450

Set options on boot: Options WILL be set on boot immediately

Few questions that I'm unsure about,

1. In the Voltage settings, how do I UV'd 50mv across the board? I press the option button but there's 4 options to select

2. What does UV'd 50mv across the board do?

3. In General settings, do I tick or untick Lock Frequencies?

4. My Governor Adjustments are default settings, do I leave it as default or change it? If so which ones?

5. What does Vibration Strength do as it's on 120 at the moment, I press Apply to the pop-up when I first open KTweaker

6. What does Internal and External Read Ahead do?

7. In Set options on boot, I choose Option WILL be set on boot immediately, have I set this correct?
[Galaxy S 4 i9505 Original Android Development] _PrEzi_:
1. In the Voltage settings, how do I UV'd 50mv across the board? I press the option button but there's 4 options to select

Press two times "Subtract 25 from all.."

Before doing that notice the default Voltages, when you press once it will go minus 25 mV across all steps, press second time and Voila - -50mV global.

2. What does UV'd 50mv across the board do?

Undervolts all steps by 50mV. For me it's a bit unstable, I have -30 mV global UV.

Check by yourself every phone is different.

3. In General settings, do I tick or untick Lock Frequencies?

Ticking Lock Frequencies will "Freeze" the Frequencies for other applications. I left it unticked.

4. My Governor Adjustments are default settings, do I leave it as default or change it? If so which ones?

As it is said in the Recommended Settings by ktoonz :

Governor Adjustments: All default settings

5. What does Vibration Strength do as it's on 120 at the moment, I press Apply to the pop-up when I first open KTweaker

Mine also, it sets the default strength of Vibration. If you want it to be less intensive set it to lower value.

6. What does Internal and External Read Ahead do?

It improves the read/write performance from/to SD Card by building a "prebuffer" for those operations.

7. In Set options on boot, I choose Option WILL be set on boot immediately, have I set this correct?

Well, if you are sure of your settings then yes. I've set mine to be onboot with 20 seconds delay.

That way if something goes wrong - I can quickly access the Ktweak and alter the settings.
[Galaxy S 4 i9505 Original Android Development] DuckMcQUack:
I dindn't get it so i left this option at the value i found it in stock settings. I see that ktoonsez have this value higher than default. What does this prebuffer do? I leaved it as it was because i tought it was something related to write\read speed that could have damaged my internal SD card.

Can we all have a more detailed explaination??

Thanks for your insights, i clicked TY on you :D
[Galaxy S 4 i9505 Original Android Development] _PrEzi_:
Well the parameter alters the cache sizes for read and write operations.

This is considered safe for SD-Cards and greatly improves the write and read speeds (You can test it with SD Tools).

It acts similar to Windows programs like TeraCopy, FastCopy etc. which build also an internal cache for read/write operations.

The only side effect of setting the values too high is either - degradation of performance (that's why ktoonz recommends 3MB, I actually set for mine 2MB - on a trial test-error basis) or - some users reported skipping of music when listening via e.g. PowerAMP.

If you have such problems - alter the values and test again.

As far as I know there is also a little bit risk of data lost that was not yet written to SD Card and still remains in the buffer and your phone crashes (but this risk is always there, even with the default buffer). When you shut down/reboot your phone it purges the cache before shutting down/rebooting, so this has no side effect in that case.

Thanks for answering the questions that I'm not sure about, but have few more that I'm not certain about

Undervolt means it will use less power? If so I'll play on the safe side and go for -25 mV to all steps

Can you describe to me what each one of these do?

sync_extra_cores

touch_boost_cpu_all_cores

touch_boost_cpu

sampling_rate_screen_off

I don't have disable_hotplugging_chrg as I'm using version 7.7 as people said there were problems with newer version but I don't think I'm missing out much

I've ordered a Samsung 16GB Class 10 UHS-1 MicroSD card, when it arrives, what format do I format the MicroSD card to? I'll store Pictures, Musics and other files on the card

Also what software do you suggest to use to track down what's using the battery and maybe wakelocks or other information
[Galaxy S 4 i9505 Original Android Development] _PrEzi_:
>>Undervolt means it will use less power? If so I'll play on the safe side and go for -25 mV to all steps

Correct. Usually the power-envelope is set for all CPUs to be on a safe side, and we have some room for improvement if we fine - tune those settings.

You can Try several uV values - just set your Ktweak to apply the settings after a while - then you'll be on a safe side and can always revert them back if something goes wrong. Other possibility is to write the uV values down, disable onboot applying and test them in benchmarks, under load etc.

Once you are sure they are safe and stable - enable the applying on boot.

>>Can you describe to me what each one of these do?

>>sync_extra_cores

Sorry but I don't have this in the head... search this thread - it was all described by ktoonz.

I have it set as 0

>>touch_boost_cpu_all_cores

Once you touch the screen it will either - boost (fire up) all cores (1) or not (0)

Personally I have it on 0, if you have stability issues set to 1 (0 conserves more battery)

>> touch_boost_cpu

The boost value in MHz that will be set once You touch the screen (I have it set to 1242)

>>sampling_rate_screen_off

Once the screen is off the sampling rate (check/update rate ?) will go down (less frequent = higher value = conserve battery)

-> I have it on 90000

>>I don't have disable_hotplugging_chrg as I'm using version 7.7 as people said there were problems with newer version but I don't think I'm >> missing out much

Well. I myself have the latest one... love to test things out. Rock stable and kicking :)

>>I've ordered a Samsung 16GB Class 10 UHS-1 MicroSD card, when it arrives, what format do I format the MicroSD card to? I'll store Pictures, >>Musics and other files on the card

Try the usual thing - Fat32. Please note that it has problems with files over 4GB -> then you might try exFat or ext4.

But first try the 'casual' FAT32.

>>Also what software do you suggest to use to track down what's using the battery and maybe wakelocks or other information

BetterBatteryStats

Usually the biggest power-hogs are Google-related apps (Maps, Music etc. and Facebook/Talk/Twitter).

Either disable/freeze with it TitaniumBackup / other soft or if you want to use them - Greenify with Greenify.

Hey,

Wanted to try this popular kernel but EVERY time the screen goes off I am not able to wake it, it just lights up the display and in few seconds it reboots.

I am running Omega ROM 8.0 (didn't tried KT on lower versions of Omega). Tried different governors (ktoonservativeq, intellidea) but the situation is the same. I am running with the settings from post #3, I have disabled "no extra cores screen off" (it is 0 now), still the same.

Run a few benchmarks, you might also try System Stability Test app - I like it cause you can 'lock' the frequency you are testing currently.

And try a few rounds of turning screen off, waiting and waking the phone - this tests the wakeup from deepsleep etc.

Third is to test when someone calls you and when you call to someone.

If it doesn't crash or behaves weirdly - stable.

Fast Charging - yes, I'm using it,

As I've said - nearly all the wakelocks are related either to Facebook hog, K9 mail, Micro messenger or Ebay app. A few relate to SHealth.

If you use any of those apps and you don't want them to stay in background then you might consider Greenify'ing them.

When using data cable it will disable MTP mode (no data transfer possible) and just pull more power to charge your phone from USB port.
