(Q) Fast Five App Lags

Even when i Over-clock my phone and have the governor set on to on-demand.
It lags a bit and seems like its FPS is low but then will go to max FPS but then drag down again its weird.
Im on Genocide right now and its funny if i UV my frequencies by -25 to -50mv for 200-1200. its still heats up to about 100*F and thats with the charger on but if charger is off it cools down to about 86*F?
Why is my phone heating up just because its on charger and why does it lag even when OC'ed?

Its normal for it to heat you like that on the charger. Mine gets real hit too. As far as the other question change the scaling of the kernel. On demand can be like that sometimes. It tried to stay at the lowest speed but it will go up higher if need br and that is why u are getting a little lag at first.

The problem with that though is on-demand is more geared to stay higher whereas conservative just keeps low, and the only other one that works is also performance but that keeps it up as high as you have it set to which will then heat even faster.
With or without the charger

[Q] What 3D gaming performance should I be getting?

So, I seem to be getting really poor 3D performance out of my Galaxy Nexus, and would like to know if I should be worried.
Something like Shadowgun will fluctuate between running pretty smoothly (30-40 fps, I guess) and chopping noticeably (15-20 fps) on my phone, whereas other people report it running perfectly smoothly on their GNs. Even simpler 3D games like Wind-Up Knight or Cordy fail to run smoothly on my phone, constantly feeling a bit choppy and occasionally dropping to pretty bad framerates. A game that does run very smoothly is Minecraft, but it seems to be something of an exception.
What are your experiences? What version of Android are you running? I'm on 4.0.2 stock, and I'm trying to figure out if my issues have something to do with that (I've found some accounts of people claiming their performance dropped with the 4.0.2 update) or if my phone is actually not giving me the performance I should be getting.

I was playing Shadowgun last night and was amazed at how fast and smooth it was. No lag or stutter that I could notice, but I have no idea what fps I was pulling.
I'm running the latest GummyNex and Franco kernel. I highly recommend both.

Yeah, that doesn't sound at all like my experience. In the very first area of the game, the framerate was noticeably low on my phone, especially when looking out over the open area (it got a bit better when close to walls, etc.). And again, I'd like to find out if this difference is because I'm running 4.0.2 stock or if it's something else.
Could a certain GN unit really have significantly worse 3D performance than another without there being something seriously wrong with the GPU (which would probably show up in other ways as well, such as visual artifacts, etc.)? I seem to be getting similar scores to other non-overclocked GNs in benchmarks such as Antutu (yeah, I know they are not a good measure of performance, but I figured they could at least be useful when comparing the performance of different units of the same model).

Samsung Tab Pro 8.4 - Overheating and rebooting during gaming??

OK, someone is willingly to sell me a Tab Pro 8.4 for a good price. Now everything works well, except for small fly in the ointment. He said while heavy gaming sometimes the tablet reboots. SO not sure if this is a software or hardware issue?

I have personally never had this problem, nor have I ever heard of other people getting this problem. The 8.4 can get pretty hot on the left side in the middle, where I assume the processor is located, though. Seems like a hardware problem specific to that tablet though, maybe a bad batch of CPU's.

Nor have I, seller says everything works just really heavy gaming that its rebooted at times.

Shouldn't reboot, the tablet has thermal monitoring and will down-clock the cpu if it gets too hot, it could be a software issue or a problem with knox as that is known to reboot the tablet...
maybe it was a return and someone installed a custom firmware then flashed it back to stock.
Though can't really rule out the possibility of a buggy game, some apps such as reicast will cause this tablet to reboot due to a kernel bug / snapdragon bug (on stock firmware).

I have tab 8.4 and it heats fast when I play some racing or 3D games (example Asphalt 8, NFS:MW,Roblox,Minecraft,etc) or even if I watch YouTube videos on 1080p60 or 4K for about 10mins. And when it overheats, performance is worse than not overheated(on YouTube, not a big effect). That thing is only when I play that game or watch that video. Can I somehow make it not overheat without losing performance?

if you are rooted you can downclock the cpu or limit the number of cores active at one time.
Turning the screen brightness down can help too.

I am NOT rooted, brightness is about 20%.

Poking around with the kernel, and experiencing this myself, the cores are pretty hefty and can generate some heat under full power. The GPU is not so hefty, so can generate heat when overworked (e.g., by playing games). It underclocks itself to protect against overheating, but of it gets to a certain temperature, it will restart to remove the load on the cores and stop the generation of heat. There is nothing adversely wrong with your device. That's supposed to happen. Trust me. I have had the Tab Pro for a while.

Big Cores are always stopped!

Hey Guys,
i have a problem with my Nexus 5X since weeks and now I think I have founded the problem. On daily usage, in games or in Benchmarks: the two big Cores are always stopped. Bit I don't know why. I have tested it with some Games, Geekbench and CPU-Z. Can anyone help me?
Thanks

The thermal throttle stops the big cores when they reach a certain temperature. It's "normal" behavior on this cpu.

But they are stopped all time. When I Power on the device and start a big game, when I wake up the device after a while and play a big game... ever! Temperatures are round about 55°C

If you're on one of the Android N Dev Previews then it is probably the well known bug that shuts the big cores off. If you're on Marshmallow then it is most likely thermal throttling. I think the big cores turn off at about 45C.

Okay. But why does my device heat up so fast? I have read a few Tests and the Processor never gets hotter then 42°C.

It's your use mostlikely, e.g. camera (, cpu intensive games, benchmarks etc) takes all the cpu power possible, that'll heat up your device into range of thermal throttling in no time, while one can browser normal websides for hours without any signifcant heat building up.

I think it's a general misunderstanding of how a big.little cluster cpu works. Those aren't 6 equal cores, the big ones are (most of the time) just there for short term boosts and otherwise drag down performance overall, especially when the cpu heats up. I can see a much higher use of the big cores e.g. when loading websides compared to gaming, where it comes down to how the game can run on the remaining cores (little ones) after a few minutes.

But the Cores shouldn't heat up after a few seconds, should they? And they are simply alsways off.
I have tested it with the Geekbench 3, Smash Hit and the Camera App. The results like the temperature and the clock Speed came from CPU-Z.
My Standard result of the Geekbench is 650 and 2500 points. The two big Cores are stopped and the temperature is round about 50°C
The Standard witch I have found in the Internet was 1300 and 3600 points. The temperature shoult be round about 42°C-44°C

In-game performance issues. But why?!

Hi there! I have a Galaxy Tab S4, as you can imagine. I use it as my gaming device. The only game I play is Rues Of Survival. And well, Among us, but I don't even take it into consideration as a demanding game.
The tablet is not rooted but I debloated it with adb as far as I could. Android 10 on board.
Probably this crappy game became so poorly optimized that the performance degraded over time.
Now I am at a point where it's pretty unplayable even if I lower the resolution.
Let's see what I have tried so far.
I have checked the usage of CPU, GPU, temp and FPS with the game launcher plug-in. I have an average of 60 FPS with an average CPU usage of 8% and an average GPU usage of 80%. The problem occurs during crowded scenes. The FPS drop to 30, making the whole thing sutter really hard, the CPU usage stays the same and the GPU usage drops to 60%. WHY THE HECK?!
I have tried a couple of different resolutions (the game does not specifically states to how many pixels correspond each d*mn option) with close to no improvements. The graphics got really ugly, obviously.
Should I try to root and disable DVFS? Should I root and lower the resolution of the whole tablet to a normal fullHD with terminal? Should I stop complaining? Should I quit playing? Should I get a new tablet?
It seems pretty absurd that a game that I was able to play on my Galaxy S6, now got so demanding. Or that a 500 euros tablet aged so badly in two years.
Are those 2 free GB of ram out of 4 not enough to handle the game?
I can play it quite flawlessly on my OnePlus Nord. But this is NOT an option. The hardware specs of the two devices should be comparable. What mostly changes are the screen resolution (lower on the OP Nord) and the ram size (double on the OP Nord).

I doesn't try that game, but I played others (pubg (highers settings), stardew valley, this war of mine... etc), and I have not had problems at all. I'm stock. Have you try game booster?
