(Question) CPU frequency control

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 .

What are your GTA III display settings?

I've made this thread to help people find some good settings to help reduce the lag.
Please state:
Draw Distance
Screen Resolution
Visual Effects
Dynamic shadows
If you have overclocked (If yes how many MHz/GHz)
Do you lag? (Lots, Some, When traveling fast, none at all)
I'm just curious of what the best settings are to make the game look good and run smoothly and I'm sure many people are wondering the same.
To start off with I'll say my settings.
Draw Distance: 43%
Screen Resolution: 66%
Visual Effects: high
Dynamic shadows: On
Overclocked? Yes, 1.613 GHz
Do you lag? A little bit, mainly when traveling fast.

Draw Distance: 81%
Screen Resolution: 79%
Visual Effects: max
Dynamic shadows: On
Overclocked? no.
Do you lag? rarely and usually only on the middle island but rarely.
My device is rooted with bloat removed but no overclock, r800a (rogers)

That's quite good mine lags quite a bit even with low settings
My modifications are
Draw distance 50%
Screen resolution: 50%
Visual Effects: Low
Dynamic Shadows: Off
Overclocked: No
Do you lag? yes it does when there's a lot going on.

Can you post a video? I'd like to see just how rarely it lags with those settings.

Draw Distance: 60
Screen Resolution: 70
Visual Effects: Max
Dynamic shadows: On
If you have overclocked (1.9 ghz)
Do you lag? Yep. Upon first starting the game I will have some lag while it fills memory I'm guessing, and it will lag a bit every few blocks. It's not game breaking, but an annoyance that keeps me from diving in hardcore.

I have noticed that how much free ram you have when you start the game makes a HUGE difference to lagging....
I had alot of apps installed and usually had around 100mb free ram when i close all apps in my go launcher, but after uninstalling almost all of my apps that i dont use, and removing ram heavy apps, i managed to get my free ram to 200mb before launching gta and the difference was amazing!
More ram = less lag

My game lags even when running on low. I have tried the usual things like cleaning memory (I have at least 200 MB of RAM free consistenly), rebooting the phone, reinstalling the game, even restoring factory settings. Patch 1.3 made a small performance increase over 1.2, but like I've said in the beginning, I can't really enjoy it. My phone is R800i with stock firmware. I've been playing like this for months and now it's starting to annoy me.
Can somebody help me please?'
Draw distance: 55
Screen resolution: 70
Visual effects: low
Dynamic shadows: off
Not overclocked.

Maybe turn the draw distance down? It's a small screen, you can get away with it. These settings have nice nearfield detail. Things pop out of the middle distance in some places, but I'm used to old school handhelds where that might be absolutely fine. I found the game lags regardless even below these settings, but I also couldn't go above them.
Draw Distance: 37%
Screen Resolution: 90%
Visual Effects: Medium
Dynamic Shadows: On
Do you overclock: Only if there is lag that annoys me
On stock kernel, there were pockets of low framerate in the middle island and when there were a lot of cars but it wasn't so objectionable that I couldn't play through it. Then on Doomkernel for some reason it was a more annoying kind of lag at 1GHz, but 1.2-1.4GHz makes it play great, with a good sensation of speed for the sports cars, but I don't like overclocking too much. But perhaps it wasn't the kernel, perhaps my rom had got a little more bloated. What's weird is that it occasionally ran perfectly at 1GHz, but I couldn't reproduce those conditions at will. I'm on ICS beta now, where GTA crashes the phone horrendously.

I'm using my ROM, and GTA III v1.3.
Draw Distance - 34%
Screen Resolution - 59%
Visual Effects - High
Dynamic shadows - On
OC - Yes, my frequency is 364.8 MHz - 1305.6 MHz
I think I don't have lags, maybe sometime when some new things on map loading.

I've tried reducing Draw distance and it does have an impact on the performance.
I never realized it was this big, reason why I've been ignoring it. Might try OC and root to remove some of the bloatware
Thanks for the help.

On stock gingerbread 2.3.4:
Draw Distance - 100%
Screen Resolution - 100%
Visual Effects - max
Dynamic shadows - on
If you have overclocked - 2.0 GHz, smartass v2
Do you lag? Rarely, only when traveling very fast with 6 stars wanted level (due to multiple choppers, cops, tanks, etc + map loading)
Sacrifice battery life for performance, leaving it with only 2 hours and a half of gameplay with full charge and half of the brightness (the screen is pretty dim anyways )
On FXP CM9:
Draw Distance - 1% (can't see anything)
Screen Resolution - min (looks UGLY)
Visual Effects - min (no lights or blood)
Dynamic shadows - off (static shadows)
If you have overclocked - 1.6 GHz, ondemand
Do you lag? Yes, when there are more than say, 4 peds or 2 cars on screen. When having lots of stuff going on, the device and the OS completely crash
Definitely in need for a new ICS rom.

[BUG] MX player not using high powered cores to decode

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.

Best battery rom for video playback?

Hi,
I'm currently using a 7.1.1 rom and I can't watch a full movie. I charge this to 100% and I watched the john wick 2, battery didn't last even that much. Brightness was at medium. Used MX player.
Can anyone tell me about the roms you are using? at least a rom that last for 5 hours in video playback

Go for elemental X kernel...!!
I'm running it with pure Nexus 7.1.1

ROM doesn't matter, change your kernel settings. Open the CPU monitor in developer options and tune your governor to keep the CPU as low as possible without the movie skipping. Or set up a different governor profile for movies that limits the CPU to 2 cores max and 1ghz.

[GUIDE] How to Really improve the gaming framerates on your Mi A1

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.
