Is it possible to turn off Vsync for the et4g?? Just looking for some higher quad scores as I'm a certified junkie

It sems there is a fps cap on our Desire HDs. In games and benchmarks, the limit seems to be around 59-60 fps. Is there any possible way to remove this? And yes, I know our screens are 60hz, but still...
Under ROM development as I understand it is something to do with kernels...
Sounds like v-sync is on. If that is the case and if it were turned off to allow more then 60fps you would get screen tearing and screen tearing looks terrible.
V-sync is a good thing, it keeps frames that are drawn in sync with the refresh rate of the screen.
There is no reason to turn it off, maybe the menus and stuff will be faster but definitely not smoother.
That's not always the case, my friend Generally i'm more interested to see what type of framerates this baby can hit!
Well that's true, in that case it will have to be turned off. In WinMo it was a matter of changing a registry entry but on Android probably more complicated. Like you mentioned, a modified kernel most probably.
I would actually be interested aswell in seeing what this beast can do to.
Hmmm...me ad my friend were experimemting around with our phones, I have a Desire Hd and he has a Galaxy S....generally Galaxy S is more powerful in 3D graphics. However, even though he built a custom gingerbread rom, my cpu was faster (quadrant rated mine 6600 at 998mhz vs his at 1024 mhz giving 5400). Another interesting find was that overclocking q hummingbird decreases gpu performance to speed up cpu operations. I assume the gpu is underclocked to provide more power to the cpu. However, at extremes (1.6ghz) it seems his gpu also overclocks, thus crashing the system. I was thinking if it were possible to overclock the gpu on a desire hd, or at least reroute power from the cpu to the gpu via software codes...
Note: contains theoretical assumptions
I need a link to a tutorial for the epic 4G please.
Can anyone explain in a couple of sentences why undervolting is good? Does it save battery life? If so, how much?
Also, how much of an improvement are you getting in tasks like playing and recording video from overclocking? What functions of the phone benefit the most and are there any battery-life effects from it?
Thanks

Improvements are small, but everything counts - bad analogy > 10volts uses more electricity than 9volts - if you could make your CPU run at 1ghz with 9volts instead of 10volts, you would be saving electricity, ie battery.
With that being said, lets say CPU's from the factory can run at 1ghz at 10volts plus or minus 1volt, but they set it at 10 volts because they know it will run safely, even though it could run at 1ghz with 9volts. But not all CPU's are created equal - so similar 1ghz CPU from the factory will have some variance. Some 1ghz CPU's instead of saying they run at 10volts plus or minus 1volt, they may have a specification of running a 1ghz CPU at 10volts plus or minus 1/2 a volt - that's why when some people try and undervolt to much, their phone might lock up - and then there are 1ghz CPU's that can't undervolt at all and must always have 10volts to even run.
Over simplified, but you should get the idea.
Okay so I was busy playing Osmos HD (Awesome Game) and my phone started freaking out. I got a notification, Telling me that my phone was over 60°C and was going to power off until the device was cool enough so that no permanent damage is done. When I turned the device back on I noticed that I had a few twitchy pixels that were flashing like the notification led only more eradicate, Over the area where the main heat source was. Its been 2 hours now and my battery temp is at 49.1°C. And the device is finally stable enough to use, Although I still have the group of twitchy pixels.
I am outraged at the fact that whilst playing a game (Not whilst being charged) that the phone can get this hot, I mean can't HTC find a way to dissipate the heat better so that the phone doesn't fizzle and burn itself out thanks to the main feature of it (Tegra 3). I'm going to wait and see weather the GS3 is any good, But until then I'm going to put some aluminum tape on the inside of a case so that the device can dissipate heat better, the aluminum acting somewhat like a heat sink.
Now I don't know weather the temperature is accurate on the CPU but f**k me sideways that's not right!

Doesn't surprise me atall mate, mine has been doing the same since the day I bought it, right ****ing disappointment this phone, wish I waited for the SGS3.
I suspect you may be having the same issue I did. The gmail app has a bug in it which can lead the background sync service to sit chewing on CPU, if you use gmail try to disable sync and stop using the app (you can 'Disable' it too), use HTC mail instead.

There's your problem: "Performance" governor.
It will run your phone at full speed all the time. Switch it to "On Demand" or "Interactive" to give your phone a break.
It's up to you.
mine also heating
My cell also got heated ALOT once
oh boy
OK All HTC One X Tegra 3 Owners should understand that Tegra 3 is a variable SMP architecture
Meaning: The chip is meant to scale up and down and into the maximum of its thermal limits and out, this is the direction NV is taking and you can see it in their latest Kepler GPUS
which means never ever lock the clocks!
You have chosen Performance governor which locks it at a minimum of 1.4ghz what is worse is that in that mode, 2 cores are even disabled so you are actually loosing performance and not gaining!
run glowball in performance governor and watch how the frame rate hits bottom
Modes:
1.5ghz = single core
1.4ghz = dual/three cores
1.2ghz = quad cores
Governors
OnDemand = can use all the cores and all the steps, conservative and power efficient
Interactive = uses all the cores and all the steps but stays in top speeds more often
Performance = locks it to 2 cores @ 1.4ghz
and finally the GPU can run up to 533mhz depending on the CPU clock, this is a very high range for a 40nm chip and hence it needs to ramps down when its not needed to cool down!
You bought Tegra3 knowing its a quad 40nm SOC, this the thermal envelope of this SOC no surprises here!
To add some perspective to your drama, use an iPad3 for few minutes and you will understand quad CPU or GPU in a mobile device this season = heat = ITS OK
I dont understand why all the nagging when both HTC and Apple said these are normal operational temps during heavy use

Oh boy, you're a god. HTC should hire you. Google too. And Apple.

I see a 153mhz GPU speed/ voltage. Is this ever used/ if so, is it when the screen is off or something?
I recently discovered that the sd 865 can be oc to 950 MHz and beat the sd888 while using less power and producing less heat ! So I want to know which brand is best in terms of overclocking and support for 120 fps in games even if the phone doesn’t natively support 120 fps , in which brand you can unlock it after rooting and oc the sd865 to 950 MHz and has an app to disable the thermal threshold ? Thanks in advance
OCing increases power usage and with that comes increased heat. CPU cycles aren't free...

I know thats why I’m planning on cooling it with a custom solution but I what I meant is that the sd865 overclocked still uses less power than 888 and produces less heat

The 888 may be unbalanced heavily favoring gaming at the cost of not be able to do other activities efficiently. Could be a 5nm flop. Not every chipset is a winner
My 7mm 855 does very well, the 865 is a solid chipset.

Oneplus 8 series , Poco f2 Pro Mi 10 series Mi 10T and Red Magic 5G /5S
865 doesn't overheat and uses still less power consumption than 888 even with OC
