I seriously think that the transformer prime has a software fps limiter. Such as Sync to vblank or sync to refresh rate. <-- they are the same thing... because on the prime Every game/benchmark I get exactly 60 fps. This is the normal refresh rate of most monitors/screens. This is also normal for vblank to max out and stabilize at 60 fps. So my question is how do we turn it off. I have seen some settings in build.prop for qualcomm devices but nothing for the tegra 3. Anyone have any ideas on how to un-limit the GPU?
bump. interesting topic, ill stay tuned to see how this turns out.

I would not doubt it if it was limited. There is no sense in going any higher than 60 fps on a 60hz display. Also good for saving battery and performance.

true but if we unlimit it then we can brag about having more fps than the apple ipad 3
Well, it would change any benchmark scores based on the graphics grunt.
It could decrease the gap between Tegra 3 and others, but would be a waste of battery in everyday use.
I don't think we could uncap it tbh, the display drivers are closed source blobs, IIRC.

So.....I feel like a noob asking, but what does FPS stand for?
And what is the difference between FPS capped and FPS uncapped?
lol small question
First person shooter. Modern warfare 2 anyone?
Trigger 3.2
Frames Per Second. When the FPS is capped it means the phone can only display games/videos at a certain FPS and it may look a little choppy. When FPS is uncalled, the FPS is as fast as the phone's hardware will allow.

Thank You!
Also note that at present any ability to achieve over 60 fps is just for bragging rights. I don't know of any game or video content that runs at more than that. Movies are typically either "24" or "30" fps. I use quotes because that 30 is actually 29.98 or 29.97, IIRC, and 24 isn't 24 either.
The point is, if your phone does 60, it's plenty.
yup we use 30fps here in the USA because of the electricity frequency is 60cycle per sec (60÷2). This is called ntsc......... other places in the world electricity frequency is 50 cycle per sec so.........**drum roll** their fps is 25 (50÷2) Just interesting FYI
In our phone record it is not as important because the system they are using is flash
I flashed the cm7 1.4 240-325-300 Kernel.
In my settings what should I keep my min and max at for all time usage?
I max them and my quad score is like 5501
don't know if your supposed to keep those certain.
Also does decrease or increase battery life.
I left mine at the default values. Was wondering this myself though. How do you test quad scores?

You want the lowest value to be at the lowest(216 i think) because this allows the processor to idle at that low speed, if you keep the minimum speed at 1ghz your processor will ALWAYS be running 1ghz at the lowest, and that will be an obvious way to kill your battery in no time. So set that to the lowest, and for the maximum i personally run mine at 750 for CM9, think i had it at 800 for CM7 but cannot remember for sure. This is limiting how fast the processor can run so the lower the better as far as battery goes. It comes down to you personally, if you game and do processor heavy tasks often then having the processor underclocked like i run mine will affect your gaming/app/overall experience. Its always like 2 clicks away to bump it up to a higher speed and i have a link on my home screen so if i do decide to do anything processor heavy i can bump it up quickly. But in general it takes more power for your processor to run higher so if your really concerned about battery life try bringing it down. I can still score a solid 1,500+(with a bunch of crap installed on my Photon mind you) on CM9 with my max at 750 and min and 216. Benchmarks are honestly just a number, it comes down to how if performs for you and what you are doing with your phone.
Awesome, I'm lowering it now and battery is dropping slow so its good, thanks for the detailed reply.

Just wanted to know what you guys/girls clock ur phones at and how low u keep it at.
I have been keeping it at 594MHz with lag free gov with both cores active and GPU overclocked to the max
Gives me a decent battery life with less lag than expected (except in 3D gaming)
On mwakious3Dtransformer v3.5
So what clock do ur keep ur EVO at? and comment on smoothness and battery

I underclocked mine to 400 something before. Lower than that Pandora started skipping and my screen would lock up before I could even get into the phone.
What is the battery differnce between keeping it on 594 mhz compared to... 1566mhz, for example? Is the battery life difference huge, or just a few more hours of standby?
Discussions that I have read here and there said that overclocking makes very little battery difference and from my logic, I tend to believe that... Most of my consumption is being done by the screen itself...

I forgot to say I was on gingerbread when I did my experiment. I streamed Pandora for about 12 hours at 486 with the screen off almost the whole time.

I completely agree with you. I keep mine clocked at 1674 and I see no difference in battery life at all. It may get a little odd if I turn minimum frequency down to 384. In standby the max clock makes really minimal difference by my own experience.
We have smashed into the performance ceiling. Without active cooling or massive increases in efficiency through improved architecture, there is no way smartphones (or tablets) can become more powerful.
I can't use 75% of this phone's potential performance while playing San Andreas. With a custom kernel and thermal throttling disabled, the phone shoots up to 90c in minutes and then reboots; that is with 'On Demand' and max frequency at 1.73 ghz.
Coming from a gnex (max stock freq. could reach 80c), absolute performance has become meaningless. Maybe it has been for a while.
This is absolutely true. We need fans or cooling systems if we shall be able to take full advantage of the massive powers in our phones. For now, I think the only way is to play our favorite games in a freezer.

otherwise lg would melt ...
or, you can root your phone and disable thermal throttle. then you can use it at full performance up until you reach the thermal shutdown temp without worrying your cpu being thermally throttled
and i had a gnex as well, it could reach 110C. i always turned off thermal throttle, and always turn off thermal throttle on my nexus 5. you dont reach thermal shutdown without actively trying too, and the cpu doesn't get throttled.

While that statement was not even close to being true when you posted it, tomorrow it'll be less true, etc etc.
If you build the exact same chip with a smaller die process, the smaller die process chip will be more efficient (cooler) and faster. Then there are of course other improvements that are continuously being made, more cores to spread the load, faster ram to reduce bottlenecks, etc, etc, again, all while getting faster and cooler because of improved production methods.
So no, phones will get more powerful, more ram, better screens etc.. Maybe someday we'll have another battery breakthrough, but right now with the massive push on efficiency we're getting some runtime back on batteries, etc.

Actually it is true. The performance on the G2 is limited by heat. You can't run the phone under load at or near its max specified frequency for any reasonable period of time. Try it yourself. To deny that is to deny facts.
Also, a smaller die reduces the surface area for the dissipation of heat.

Time ago a saw a cooling case. If i find the site again, i will post it.
Imagine the HTC One, but with a heat pipe transferring heat from the SOC to the aluminum case... That would provide more cooling, but I'm not sure of the size penalty of the heat pipe.
Also, more efficient chips CAN provide more power and generate less heat. A perfect example is Intel's pentium4 "netburst" architecture vs the newer and considerably more efficient "core duo" chips.
Take care

are there any phones out there that don't heat up while performing great in all demanding titles?
Sent from my LG-D801 using xda app-developers app
well yeah smartphones aren't designed to run at 100% of the cpu/gpu speed for long periods of time. If they were, they would have to be a lot bigger and/or have active cooling. I guess I never really noticed the "wall" because all the mobile games I play do not push the phone to the limit. When you are comparing it to the past though, remember the newest CPUs are significantly faster clock for clock. 1.5ghz is not the same for an A9 vs Krait 400.
So what iz the solution ? Do we have any modification or init.d script to disable that cooling system ?
Solution Is a thermal pad on CPU

So after screwing around for about an hour trying to find the PVS bin of my Z2, I finally found out how
1. You need root
2. Go to sys/module/clock_krait_8974/parameters
3. Open table_name and your PVS is shown right there!!
Well I think I got really lucky as I have the highest binned CPU, PVS 15!
What bin do you guys have?
edit: Also can you guys tell us if your phone overheats when recording 4k video? I still get the overheating after like 4 minutes despite having a high PVS

Not important. The process vary among different wafer lot. The process variations are identified during production test, supply voltage will be set according to different process.

What is the point of this? Can someone give us a clear answer? Does this help to reduce phone overheating.
Chips are not all equal for most all devices. Some are better than others. Typically the chips that are not as good require more voltage to keep them stable especially at their low frequencies.
When the phone starts it will read the setting set by the chipmaker, the setting determines what voltage table to use.
The phones that can run on lower voltages will have slightly better battery life and run slightly cooler.

Higher is better, also with a higher bin, you can also overlook much more
In fact, this explains everything and helps you with voltages needed to overclock. http://www.xda-developers.com/andro...-guide-helps-you-make-the-most-from-your-soc/
Normally once the CPU is getting towards the top of its performance all chips will be set to "max voltage". Eg I doubt any of the z2's are any different with voltages from about 1.5ghz upwards.
So when the CPU is draining the most power and generating the most heat the devices will all start performing closer and closer. The biggest differences between the CPU's is at low frequencies and how far you can overclock. Also users might start under or over voltage, and the stability while doing that will vary.
So high performance things like 4k video are unlikely to be all that different, all CPUs all be at high CPU freqs so will all be at max voltage.
Does anyone actually have the voltage tables for the z2's?
