Choppy/Framerate Issue When Gaming?

Hello, everyone.
Thought I'd take this question to XDA, since I'm unsure if I have a defective unit or not.
I have a HTC One (obviously) and it's stock, unrooted 4.1.2, running the latest 1.29 update. But when playing some games, I've noticed that ever 2 or 3 seconds, I'd get some sort of...frame jump, or random choppyness when playing. It's not framerate lag as far as I can tell, and when running benchmark tests, they appear to be fine.
The games I have tried where I can see this issue are:
-Mini Motor Racing
-Ski Safari
-Temple Run 2
I don't game that often, but these are the games I mainly play when I do. I know that not all CPUs/GPUs are made equally, so some people may not have this issue, but some *hopefully* might.
But as I say, when I run an AnTuTu benchmark and watch the GPU benchmarks, I see no jitter or jumping.
I'm wondering if I have a defective GPU or not, and just wanted to see if people are in the same situation as me.

It could be that 4.1.2 doesn't have optimized GPU drivers for the Snapdragon S4 processor. 4.2.2 runs games like butter, but I think the GPU got a speedbump on that OS. I know you said your on stock, but try applying a custom kernel like from Faux, and see if it makes a difference, maybe OC the GPU a bit.

Interesting...I didn't know that, I'll definitely give a custom kernel a try. Thanks

It's not about drivers, it's about heat throttling. HTC somehow decided that when the CPU hits 40 degrees everything should slow down to keep below that target. Which is bonkers considering many countries have ambient temps of 30+, and the speed of the monster in the One. With custom kernels you can adjust this setting and to delay the throttling.

Just another question, do you experience this issue as well?

Everyone does if it hits 40c ElementalX kernel allows it to hit 55c with the Run Hot option I believe

Thing is, when the phone is cold and below temps and I start a game, it's still pretty jumpy. So I don't think it's that.

I got the same problen..

[Q] Switching between CPU modes

Hi guys,
I may be being completely dense but on the TF700 you could switch between power saver, balanced and performance modes.
Can this be done on the TF701? I'm on 4.3 and can't find it anywhere!
Owen.

Pull down the menu from the top and choose intelligent saving. Or open the app called energy-saving and choose there what you want to choose.

That is not what he is asking. He knows that already.
He means to switch between different CPU frequencies as on the TF700 is possible.
I don't know if this is also done with the energy savings settings.
Maybe after Sbdags started to build a custom Rom he can find out if it can be done.

I can see already by playing around with the ROM files that Asus haven't set it up the same way - in fact I'm yet to see any indication of how they do it, if they even do.

I could be wrong but I read somewhere, that when your do low level tasks, like watching video, it goes to single core.

Well that is nothing new. The TF700 with Tegra 3 did that already and Tegra 4 does the same.
I guess maybe they don't lower the clock frequency just limit Wifi, brightness etc. on the TF701.

Yeah that was my wondering, a bit more 'intelligent'. Certainly can't find anything obvious in any menus or pull downs.

Checked with SystemTuner the max CPU freq when energy saving off and on.
Off: 1.91 Ghz
On: 1.7 Ghz.
So they still use it, but only 2 frequencies.

Ok good to know how it's varied, thanks!

So for normal use you can let energy saving enabled unless you want to play 3d games.
When browsing I don't see any difference in speed, also not with other applications.
But for sure running an Antutu test is will score lower.

Overclocking Kernels for the TF701t

Hi, does anyone know of any kernels available for the tf701 so we can overclock/underclock the processor better? I still am kind of new to this forum. I want to do this for overall battery life improvement and also performance improvements as a bonus. thanks for your help!!

There are none currently.
Not sure the device really needs it either. It's very fast as it and would only generate more heat and worse battery on an already hot device.
Tweaking the kernel and rom are much better options (CROMi-X )

I essentially wanted to use SetCPU in order to dramatically underclock the processor during sleep and slightly underclock it while its screen is on (because who needs all this processing power really?). This could possibly stretch out my battery life by another day. Do you think that will be possible to do when I install a different ROM on the tablet? (like yours for example)

Ah ok - download trickster mod and set the min and max freq there. SetCPU is years old and won't work with our device

with the trickster mod, would I be able to set profiles for it when I do things like turn off the screen? thanks for the suggestion!!

Nope - it just sets the min and max.

I wonder why it gets hot though. I thought these are SoC's and aren't supposed to get hot. The tf101 didnt get hot at all. But if you overclocked it to 1.6 it started to get warm.

Does anyone know if this happens as regularly on cm11 or another aosp ROM? Also, what's a good max level to clock it at so I don't constantly worry about the heat issue?

What exactly are you worried about? You can't clock it past 1.9GHz anyway which while it might get toasty it won't fry an egg or anything.

I just want to make sure getting it this warm wouldn't damage the hardware in anyway.

stock kernel

Dose the Stock 5.01 N6 kernel idle with 2 cores ? I'm watching it with prefmon app and its idiling at 300 with 2 cores always on .

you forget, stock uses mpdecision, so its always changing your cpu speeds(and cores used) as needed. and if its idling with 2 cores always, so what? my cpu idles with 4 cores always on, but thats just how i have it set.

No I no but I don't remember ever seeing any Device (stock kernel ) idiling with 2 cores . Just seems strange even with mpdecision . idiling on home screen with nothing running , doesn't seem right .

na, its alright. you wont lose extra battery because of it, if thats what you are worried about. many custom kernels include this as well, since there isnt any difference in battery loss.

Not worried about battery , I don't think its the normal behavior for stock kernel .

i go back and forth from ElementalX and stock , I no ElementalX runs 2 cores now but I already flashed back system IMG and boot img so ElementalX should be 100% gone . But ya hopefully there's still stock kernel users here on XDA ;P

Mpdecision idles 2 cores.

Max CPU frequency capped when at low battery

No this is no the same throttling issue that the Nexus 6 is known for.
I am running Lineage OS with the latest version of Popcorn Kernel. When my battery gets under 50% all four cores will still be online but the frequency will never go above 1497MHz. Even if when I change it manually in kernel Auditor it switches right back off of it.
Anyone know how I can prevent this?

You can't, as it's working AS intended.

A typo. I meant 'as'
The reason is the current drawn from the battery has to be limited to prevent sudden shutdown or crashes.
The level where this limit kicks in has to be chosen very conservativly because some devices are already more then 3 years old.
If you have a newer device with a battery not aged that much you can always compile the kernel yourself and change those values.

Have you tried turning off BCL and changing values in thermal-engine-shamu.conf file? I did both and it did the trick as it seems. Only issue I have is cpu overheat throttling.

sorry double post

If you are using LineageOS it's system/vendor/etc/thermal-engine-shamu.conf
But I would recommend only changing it if you really know what you are doing.
Wrong thermal values in this file caused the well known death of many Nexus 6p devices.

So in that case would the safest solution be to complie Popcorn Kernel 1.7 myself? I don't even know where to start with that process. All I know is that my battery isn't that old and shouldn't be throttled at 50%.

Could you recommend a value to change? I've looked through the file but I'm not sure which value would choose when the CPU throttles.
