here you go

Setup

AOKP Jan8 Romanbb Unofficial

franco r32 default settings

384/1512 interactive, row scheduler

perfmon by chainfire

room temperature: 22 degrees celsius

and to increase accuracy this time i got system tuner's notification cpu temperature (in celsius) ready so be sure

not to miss the TOP LEFT corner of each of the screenshots which the number there is showing the cpu temp

;)

Also a note: today on r31 I tested with the same system tuner notification and the phone starts to throttle (at 384) since it shows "62C"

r32 Gaming Review

i did them all in a row so, read like a story please :p

1. Need For Speed Most Wanted (00:00)

The game starts with 41C, 4 cores used for loading

At the beginning of the first race, 2 cores went to sleep and only cpu0 and cpu3 left working

dont be afraid of the sudden rise of temp from 41 to 50, its normal

The cpus did not show much movement all the way, still the 2 cores working at high freq

After a minute the cpu temp rised to 55C, no signs of throttling

I tried really really hard to make the cpu temp go up because everytime a race finishes, the temp goes down very fast in the race selection map

After 11 minutes, I finally got to the temperature that it used to start throttling in r31 - 62C

the 2 cores still working at 1512mhz

at 63C, it starts to throttle around 1026, and cpu1 + cpu2 wakes up to work due to increased demand of cpu power

IT IS STILL VERY SMOOTH

it shows a little bit of 1512 though, but just a little bit spikes then they go back down around 1026

however dont put full trust on the device reported cpu temp coz as i said it goes down really fast after a race has ended - see its just a min and its 56C now

because the temp went down, it could work without throttling and this time cpu0 and cpu1 work instead of cpu0 and cpu3

Left the game at 58C after playing for a total of 19 minutes

then opened GTA VC immediately

2. GTA VC Max Graphics (00:20)

it loads with 4 cores, and in game - similar as before, GTA is capable of waking up 4 cores even when not throttling,

but the 4 cores are not maxed at 1512 because more of them are working together

it throttled at around 62C, and it did pretty well... back to 59C

so i left the car and went on a helicopter to make it load even more landscape

I failed... I failed to make it hotter nor make it lag...

Maybe some explosions? firework? yeah finally i made my way to 63C in GTA on a tank

but still no lag, and still used a bit of 1512 though

Closed the game at 64C after 31 minutes since the beginning and went directly to MC4

3. Modern Combat 4 Zero Hour (00:32)

Opening the game with 4 cores, loading the mission with 2 cores and a cooler temp

and back to 4 cores with bits of 1512 in game

the temp is averagely around 62-64C

Until I went on a car and it drove very very fast (i.e. lots of landscape changes) and i have to aim and shoot things on it

the temp went to 66C and shows a sign of active throttling - all cores 1026 and sometimes 918

it went well and the temp quickly went down to 63C in a minute (where i am still on the fast car)

the temp went down further after i left the car - at a quieter place than the beginning of a mission

and i left the game at 59C after a total intensive gameplay of 49 minutes

4. Smaller but still graphics intensive (00:49)

decided to do abit with some non-storage-hungry-huge-huge-games

and note that they are started in a warm temperature, not from idle

Beach buggy blitz - throttling and 4 cores active

F18 carrier landing - throttling and 4 cores active

Finally, quitted games, turned of system tuner cpu temp notification (to avoid cpu usage)

and all good with cpu offline when they're not in use

Oh that must be a pain in the arse reading such a long report but hope you have enjoyed like i have :good:

Sum Up

Nothing to say.

Perfect throttle, working towards its goal which is to reduce temperature even at 1.0ghz

Perfect smooth gaming experience, over the hour tried my best with the most graphics intense games to produce a lag but really i couldn't

it doesnt lag even at 66C and the temp quickly went down after that short peak i have recorded - so hardware still protected by franco

also, even though the cpu temp is at around 60C, the general feeling is "WARM" on my hands, still comfortably playing (not even palm sweat) and just a bit "WARMER" in MC4.

Hats off and salute to you franco - from one of your extreme gaming type users :)

Luckily i have no problems other else are reporting (mainly data drops and abcxyzwtf wakelocks), so please keep on producing magic :cool:

and if, just if you have got some time, after this test, i have a question which is about the power management during heavy cpu usage, worth a consideration for perfecting the gaming part - of the almighty franco kernel (despite the fact that we never care about battery usage during gameplay)

maybe later, if you need to focus on fixing bugs! :p

Question towards perfection: 4 cores? 2 cores?

then at this point ive found that even smaller games require 4 cores

it is actually because of throttling? why at the beginning of NFS MW, it only used 2 cores at 1512?

I wonder the difference in the working mechanism of 4 cores average freq and 2 cores max freq - which one uses more power and when the device choose to use one of them?

after dinner, i made sure the phone is cool enough and opened the two smaller games again

they still activated 4 cores to work even when not throttling

and NFS MW? still 4 cores!

i turned off apps, idle the phone, make sure cpu 1 2 3 were slept again, and open NFS MW again

still 4 cores

so... what's making this difference in choosing cores? just a question towards perfection
