Devs,
The performance of le 2 is very bad when it comes to gaming.
It is the same in every stock eui to miui and all lineage os ROMs like AICP which uses lineage is kernel.
As per my finding this is due to severe thermal throttling in eui as well as in lineage os 13 and 14.1.
Firstly the two A72 CORES don't run while any task making it like SD 650 and clock go soo down at reaching 34° to 35°c and at above temp all A72 CORES ARE DOWN in lineage is and only one works in stock eui, same goes with GPU under clocking starts at 32°c making gaming experience horrible,
Even kernel auditor don't have any control in any of the ROMs and in lineage is 14.1 27 Feb build it is told it have core control but it can make all A72 cores run couldn't control clock speeds and result is the same ,
So I request devs please make a kernel from scrap and don't take hints from eui kernel and give us good gaming experience.
Thank you

I installed latest version of XenonHd rom on my LeEco Le 2 Snapdragon 652 version and I checked benchmarks are now minor low, and I also checked on cpu z , aida 64 etc apps it shows only 4x1.4Ghz a-53 core is working and 4x1.8Ghz a-72 is stopped or sleeping checked on 4 different apps also.. So I wanna know that 4x1.8ghz a-72 cores are working or not plz answer wanna flash on my other LeEco devices.

I just did that like u said but nothing happened for me and now I m back on stock eui and now I saw on 1 device its showing all a53 cores and dual core a72 and on other device only quad a53 and 1 a72 core is activate .... What should I do? plz help as I m very new to these custom roms and root process .

Try changing CPU Governor to performance in kernel auditor after turning minimum CPUs big to 4 (using this for prolonged time results in heating and draining of batter) .. And also it is normal that the phone turns off unwanted cores to save battery.. It only turns on those when needed..

I did that yesterday but doesn't work on both of my Le 2 , I did exactly the same but after restart again cpu-z and other apps all showed only quad+one core on one device and quad+dual on another device now I m confused what should I do , On eui I saw all the 8 cores working while gaming or doing heavy tasks but now performance has reduced now only a53 cores are active and a72 has stopped.. plz help right now I m back on EUI , can u plz tell me any stable rom with VOLTE support (I was on xenon hd rom from past 3 days and noticed cores issues) , I tried rr rom , lineage os , miui 8 , hexagon , etc plz help waiting for ur helpful reply

Yes the settings does not stick after restart even apply on boot option in kernel auditor doesn't help always, you have to manually change it everytime you restart or let it be in interactive.. I did not face any kind of performance issues while letting it the way it is and sorry I couldn't help you.
In the country I live now, there is no VOLTE carrier; but in official lineage os thread many have mentioned VOLTE is working for them. LOS 13.1 is the most stable ROM I have used. other roms may be stable but every rom that uses LOS 14 as base have some kind of camera problems.. You can use EUI but I don't belive in Chinese ROM because most of the inbuilt apps require unwanted permissions, it is my theory that they could steal your privacy. If you prefer EUI over Los better instal EUI 16s because 19s has **** load of bugs(for x526)

Now I had installed Los 14.1 on my Le 2 its preety smooth and fast and tested the cores I rebooted the phone and saw on cpu z hexa is activated 4 a53 and 2 a72 and benchmark score was 85K on antutu and 1500/5K something on geekbench 3 and 1400/3.5K on geekbench 4 (@ the time of benchmarks cpu z showed only a53 cores active) which is more than Le 2 on stock eui (81K and 1.4K/4.5K and 1.4K/2.2K respectively) , I m confused
How the score came out more on Los than eui ?
On eui all cores were activate and on Los only a53 are active then also high score... HOW ? and how the battery life on Los 14 I m not getting good battery life..

First do not consider benchmarks, those results are not accurate. Retesting will give you some other results. In both EUI and Los the OS knows when to use all 8 cores and when not to. Most of the time 4 a53 and 1 or 2 a72 only works. Because are meant be used only when needed.
Battery life depends upon usage.. Use greenify

During normal operation some cores are shutdown to save battery but they become active once you run benchmarking software or on heavy load.
With Mokee 7.1.1 I am getting 5-6 Hrs SOT.
When i open cpu control apps like 3c cpu manager and rom toolbox pro, the maximum frequency is set to 1.59 Mhz by default and i can't increase it. When i increase it, it again comes to 1.59. Any solution?
Using oneplus 3t
Overclocking depends on the kernel. If you are using the stock ROM and stock kernel, don't even hope.
If you have a supported kernel (not likely), use Kernel Adiutor. Much more up to date.
Also there's core control which will interfere as to make sure your CPU doesn't melt into a beautiful pile of liquid metal ?
As far as I know you shouldn't overclock your CPU, there may be some design problems with it, and becomes unstable. Sultanxda investigated the problem back in December, and it looks like even the stock rom must use some tricks (aggressive thermal throttling?) to reach maximum spec. frequency. Overclocking on custom roms lead to crashes.
Radioactive kernel for los based roms by @acuicultor has overclock. I use it and love it. Great sot, 7-9 hours easy, less if I game. I actually have the large cores underclocked to 2. though so that may help a little with my sot but it shouldn't affect it much at all

That is normal although the max frequency of the little cluster is 2.15Ghz as advertised by Qualcomm for Snapdragon 821.
According XDA review of oneplus 3T dated November 2016 https://www.xda-developers.com/oneplus-3t-xda-review-what-has-changed-and-by-how-much/ the Little cluster was clocking to 1.6Ghz (round off) as opposed to 2.15Ghz which is its maximum clockrate, it is safe to say that oneplus intentionally did that in order to save more battery.
Btw im using custom kernel ElementalX kernel based on Oxygen OS 4.1.1 and even I set the little cluster to its maximum 2.15Ghz it always reverts to 1.6Ghz.
As you can see OnePlus 3T is still blazing fast even the little cluster is a bit downclocked.

Radioactive kernel stays at 2.188Ghz for the little cluster for me even after reboot if I set it that way. I prefer 1.6Ghz, I like my insane sot. The big cluster oc at 2.419Ghz does not stay though, it automatically reverts back to 2.3Ghz. But I actually prefer to set it uc at 2.15Ghz. Still blazing fast.
EDIT: Using exkm aswell
OC more than possible
in each rom my phone show 1.4 ghz in 8core how can i over clock the cpu to 1.8 ghz or this that a issue with all the roms?
I also have this issue, even antutu score become 44000 !
I'm using los 14.1 latest build
I found that the A72 CPU cluster is disabled!

I fixed it by going back to MM, maybe it is a bug in nougat.
Try flashing a custom kernel and see if it helps
Flash this kernel, it may rectify the problem:
https://forum.xda-developers.com/le-2/development/andromodx-kernel-t3529576
I monitored the GPU and it does not stay 600mhz in heavy games.
Setting 600mhz in the Kernel Adiutor, the fps increases for a few seconds but then GPU drops to 400mhz and decreases frames.
Using CarbonROM.
With someone else does this happen?
Hello, as I mentioned I am facing low fps and poor performance in pubg and when I ran the geekbench test it games 1k in singlecore and 3k in multicore test. I am using stock oos oreo with blushark( I don't remember the name lol) kernal with unlocked bootloader. It also shows only 3 cores idk why, and the score is very low compared to other scores on browser.geekbench which shows 2k for single core and 5.5k for multicore. Please help!
I'll try to keep updating my research on this.
I did a hard reset and installed omni rom 8.1 which got me a 80% increase in single core benchmark (~1850) and 25% increase in multi core benchmark(~3925). Single core benchmarks are now around the same as of what others test results are showing in browser.geekbench, but multicore benchmark is still less. :/
Aah I settled on omni ROM 8.1 with caesium kernel and disabled touchboost and changed big cluster governer to ondemand from conservative. I now could play pubg smoothly on 1280x720p with high graphics and extreme fps thanks to gfx tool app before I couldn't even play the game with so smooth graphics and 956x500 blah blah resolution. I noticed the CPU would throttle down and reduce the frequencies for big cluster to like ~1530mhz and little to ~1350 MHz but the gameplay was good.

Stock kernel will give you the best results IMO. Try the Bane kernel, is good too

Will try that too! Thanks!
The stock kernel gave me the above result 1850 singlecore and 3900 for multicore and after caesium kernel I got 4050 in multicore and 1650 in single core. But I don't how to go back to stock kernel without reinstalling the rom :/

Use a file manager, such as Solid Explorer, to copy boot.img from the ROM zip file and flash it in TWRP by selecting Image in the install option.

I am back on the stock kernel of omni rom 8.1 which gives me a average score of 1900 in single core and 3900 in multicore tests and pubg runs great on hdr 720p 60fps although it doesn't run at full 60 fps and there are some stutters here and there but gameplay is very good.
Simple fact: oos sucks except its face unlock.
I've always wondered that apart from the obvious hardware differences which contribute to the speed difference in phones like OP7P or ROG2 etc (Storage Ufs 3 vs 2.1 in K20P),
-- what's the secret to their software optimisation too?
I've seen benchmarks on custom roms vs stock miui & the difference is visible but not much & even custom kernels have a boosted score but they are still coming only close to or slightly exceeding stock OP7P scores.
In games like pubg there is significantly lesser jank & microstutters on OP7. How come?
Are the driver's much updated or tuned or the cpu scheduler tunings very different in their base software stack?
Pubg in k20pro has a much higher frametime average & level of frame drops vs OP7, especially visible with multiple squads nearby (in-game I don't think UFS3 has a significant potential of impact once assets are loaded in the game but maybe I'm wrong?)
(In general games have better stats when tested using profiling apps on OnePlus vs K20/Mi9T)
What prevents our phone from getting to that level of fluidity?
Atm I'm using immensity kernel on miui 11 & I see it's based on caf sources & there's noticeable performance boost in scores as well as real life usage but importantly the idle drain or drain while using light apps is damn low too!
For example I've not seen <150ma live drain in simple apps or in idle on stock kernel or like on Quax which is based on stock but in Immensity I'm often seeing as low as -95ma-115ma drain which is very, very good & sign of tuned cpu schedulers & other things despite using the same rom.
^^---So is this the sign that the 855 chipset is not fully utilised/optimised by Xiaomi yet?
Even black shark 2 has lesser jitter & smoother operation in daily usage (yes it has the 855+ but it's ~15-20% faster ., seems to have much better base software!)
Can we hope things will improve officially? Or Xiaomi won't prioritize base phones that much vs their 'gaming' phones?
Personally I'm hyped about PapaSmurf kernel coming for our device too! (og made for Razor phone) :fingers-crossed:
*Rumored to come this month (or maybe in Jan!)*
(Mad props to devs like UtsavTheGreat, Xenix96,AcerVenky etc who have developed some really great kernels so far & given their precious time to the community!) :highfive: :angel::good:
