Do you know a method or an application to force CPU speed to 1Ghz or at least how to control the current speed?
I find with TCPMP that, after a boot, CPU is running at maximum speed. After a few minutes it goes down to 500 - 400 Mhz and it does not raise anymore.
With 1 Ghz TCPMP runs smooth with GDI (the driver that let me use subtitles), with 500 Mhz it begins to stutter.
Another question, do you know a version of TCPMP that let you use subtitles using directdraw drivers?
Thanks
I want to know this ,too.
How to release our HD2's CPU speed ?
I wish HD2's CPU can work in full speed all the time.
Don't worry about battery issue, If it can be control .

My xoom is on tiamat 1.4.4 and overclocked to 1.6 max and 400 something to min on interactive governer. After some stadby when i open the xoom and start playing videos, cpu stays at minimum and video files play choppy (and sometimes GUI)(even after 5 minutes of playing). When i set the minimum to a high value like 800ish, videos start playing smoothly again. Then when i again reduce the min value to 400, video player keeps using higher valued cpu levels and keeps on playing smoothly.
My guess is video player cant wake the cpu at the begining or something..
Question1 : What is the default governer of honeycomb! Does it use steady 1000mhz or scales itself between its own min and max values. (is it SetCpu's fault!)
Question2 : Is there a way to assign profiles to specific applications and tasks like
"when i play videos use 1000mhz minimum!".
I know "on demand" governer and some others are just for this but apps are not using them as they should. Sometimes SetCpu needs some "push" to give more juice.
Or is it just me!

Not sure about question 1, but Tasker can set specific CPU freqs and governers for specific apps.
so far i failed to understand the mechanics of tasker..
can someone explain? The existing manual is not helping much.
I figured it out! This tasker is amazing!!
i made a preset to control cpu with tasker to:
When i start moboplayer
-set cpu min to 912
-set cpu max to 1200
-flash "video mode on" text
When i exit moboplayer
-set cpu min to 412
-set cpu max to 1600
-flash "video mode off"
working great now..
HD video playback is smooth as silk!
Max out processor, interactive. I use no-frills setcpu, because setcpu screws around too much. No-frills gives me super smooth performance.

I agree. SetCPU is awesome for my phone (can give greater performance AND greater battery life if you use profiles), but it does wreck **** on the Xoom. Been using No-Frills for a while now, and it is much smoother.
How do you setup the "if heat goes over xx then reduce cpu to xx " part with nofrills.
As far as i understand nofrills dont have any settings or profiles.
What if cpu overheats?

The xoom will probably shut itself down before it gets too hot.
I should play around more with the different governors. Right now I'm using System Tuner to OC/OV my Xoom. I'll try No Frills next. SetCPU was on my SGSII until it started shutting itself off at random, sometimes requiring a battery pull to get it to power on again so that app will stay far from my Xoom.
Can anyone recommend any other (preferably free) apps that can OC/OV/UV and set profiles?

CPUMaster is my favorite.
I learned from reading this forum that i9500 can be better for listening music, however I have few doubts:
1. Hi resolution audio files which I listen to most require more processor power for unpacking. For example 800Mhz CPU does well job for unpacking medium compressed 24/192,000hz FLAC file in real time, however if I get Audio Monkey file with same quality but compressed as insane, then 800Mhz processor can't do the job. However Intel Celeron 1.5Ghz and 64 bits does the job right. All tests were done using JVM. So how 1.6Ghz Cortex is comparable with Celeron 1.5Ghz ?
2. Android limits sample size to 16 bits, (no AudioFormat ENCODING_PCM_24BIT constant provided even in kitkat). So additional processor power will be required for resampling and dithering. So again question is for APE 24/192 insane compressed, can Cortex take additional job for DSP?
Can somebody who owns i9500 confirm that the phone has enough power comfortably manage hi end music files in APE and WAVPACK formats?
I use Kamerton for my testing, but similar results were reported for Neutron, so if you have the former, then your data will be same helpful.
I would be happy to test it for you.
Can you please attach the file you want us to test?
Hi,
I am working on a program which reads the current GPU frequency of Android devices. For example, Adreno GPUs have a standard directory of /sys/class/kgsl/kgsl-3d0/gpuclk. The GPU frequency of Intel devices seems to be a lot more difficult to find. '/sys/class/drm/card0/gt_cur_freq_mhz' works for a few devices, but not all. Any ideas?
Thanks,
Andrew
I have a meizu MX4 (mediatek MT6595 8 core CPU in big.little configuration - 4*A7 + 4*A17) and I noticed that in some extreme cases where software decoding is required (aka a 10bit h265 video), the high powered cores are idle leaving the low powered cores to try to decode the exotic video format, unsuccessfully obviously.
I am currently on android KitKat but I can also test on android lolipop if required.
Try playing with CPU Core Limit
Settings>Decoder>Cpu core limit
You can also try "Use Speedup Tricks"

I tried changing the core limit settings, doesn't matter what settings I choose, only the low powered cores do anything but MX player detects all 8 cores.

This might be due to the the fact that SW decoder can't detect which one is faster and which one is slower.
You may get better performance by reducing number of cores to 4 to ignore slower cores.
Reducing the number of cores to 4 still uses the low powered cores exclusively. MX player simply refuses to load any of the high powered cores, no matter what setting.

It is solely kernel's decision selecting cores to be used..
Anyway I will check again if there is a way to control on it.

BTW, How did you monitor core usages? I can't find proper tool.
I'm pretty sure that choice of core usage is purely controlled by kernel logic; these big.LITTLE setups don't generally expose the cores to the OS.
Yo fellas, its your"rooting enthusiast SenpaiYank (lmao rooting enthusiast, as if such a thing exists)
Well, as you know, our device has a quite outdated and not so beefy (at all) SoC, the snapdragon 625. While its CPU is not tremendously ridiculously bad, the GPU quite is. This is not a prolem to people who don't care about games but a very prominent one on the other side.
With the help of this trick, tweak, whatever you decide to call it, you'll practically be able to play any game out there that you're not able to or play that same game at a higher setting than you would. The trick consists basically on lowering the screen resolution through a script, trading some of the visual quality for a noticeable night day performance boost. It's a common trick that works on other devices too and I've yet to find a game that had problems with it.
I'm using "profile" scripts to achieve it so you can change it on the go. I feel that way is the most ergonomic and quick one. Just run each script with root permissions according to your need. I recommend FX file explorer. Wanna play a graphically intensive game? Switch to gaming profile. Wanna do something else besides gaming? Switch to the default one.
As I side note, the trick can be done on unrooted users too but you'll need a computer and you'll have to apply the gaming profile permanently (unless you're willing to repeat the procedure whenever you want to go back to default). I can talk about it if you guys get interested on it.
Enough blah blah, how do I do it ?1st - Grab both of them (default.sh and gaming.sh)
2nd - Install (in case you don't have it), open and type this on the Terminal Emulator app:
Code:
su
To attain root access (not sure if needed but, just in case)
Code:
wm density
To get your current screen density value at 1080p (override density field).
Lets imagine you got 432.
3rd - Choose and calculate a new resolution for your gaming profile
So now lets ge to the actual work. Our device native resolution is 1080p (1920x1080) and we want to lower that.
I lower it to 810p (not a standard lmao) which is 75% of 1080p (1440x810) as it gives me agood balance between visual quality and performance. You can go even lower to something like 50% if you're ambituous about performance. At 810p I can expect a minimum of 25% performance uplift (not FPS).
So, to get your gaming profile resolution DPI, you multiply the relative percentage of it by the default profile resolution DPI.
Code:
[COLOR="darkred"]432[/COLOR] * [COLOR="RoyalBlue"]0.75[/COLOR] = [COLOR="Blue"]324[/COLOR]
This value will be your gaming resolution DPI a.k.a. the resolution from your gaming mode script.
4th - Edit default.sh and gaming.sh, apply the new values and save the files somewhere.
default.sh script should contain the values of your default resolution, in this case, 1920x1080 and 432. Size for resolution and density for DPI.
gaming.sh script should contain the values of your gaming profile resolution, in this case, 1440x810 and 324.
VOILÁ
To make the process much much easier and quicker, I use FX file explorer and its shortcut feature so I can switch between both profiles from my home screen pretty easily. Whenever I'm not playing a demanding game Is stick to the default mode, whenever I'm playing a graphically intensive game, I switch to the gaming mode and enjoy the improvement.
Cool, cool. So, is there an actual improvement in performance or is this just one of these so called placebo tricks ?It's definately not placebo and probably the most effective way around of increasing gaming performance!
I've tried to record a test with and without the trick (and failed, it doesn't look as effective in the video but I'll leave it here anyway). Take it with not 2 but 3 grains of salt due to all the uncontrallable factors that involved the scene, the actual gain in practical use is much more noticeable. The benchmark takes place in the super duper hot (pun intended) looking and intensive game, Shadowgun Legends.
On the first video, the device is running the Extreme Kernel, without the tweak, along a CPU cap of 2.5Ghz and a GPU cap of 855Mhz (or something around that). I didn't increase it further to prevent the device from overheating (which it already practically was) and because at a higher GPU clock, I would get arctifacts (my device does not support the 922Mhz frequency).

On the second video, the device is running a beta batch of the velocity kernel, with the tweak, along a CPU cap of 1.9Ghz and GPU cap of 672Mhz. I ran the device at a lower speed so you can see how useful the improvement can also be.
http://sendvid.com/fqum12jw
I ran the game at the high graphical setting (30 FPS max) on one of its most intesive scenarios and were at very high ambient temperatures (30C) so again, take the videos with a grain of salt. Used an external gamepad to play and used Scrcpy to record the screen (through wifi so, the quality and framerate from the recording is considerably worse than the actual one). You should also remember the 5-6 FPS strain of capturing the screen.
I also used game bench to monitor the framerate (top right corner) where the last 1 minute of each benchmark were with the screen capturing off. Once again, sorry for the bad quality of the recordings, I'll leave a screenshot of the game bench results.
Not willing to write a outro so, yeah, basically thats it
Here's another sample video, of the same game, this time at medium settings. Along the very noticeable smoother gameplay you can also notice how the GPU load goes down from 95-100 to 70-80 and it becomes less of the bottleneck on the scenario. With the gaming profile could I could actually remove the 30 fps cap and run the game at +30.
