[HTC One X+] ryanjsoo:
First off you must be rooted, and before you go complaining about lag, battery life, poor gaming performance, etc, have a look on the internet because chances are you either have a faulty device or someone has already created a fix. Many new phone manufacturers will market their device as quad or even octa core, tricking the market into believing that smooth gaming and UI are a result of having a 1.7ghz quad core or such when in reality the chip pushing the pixels is the GPU, probably the most important factor in a chipset which gets likewise upgraded every generation but is not advertised as heavily as the CPU.

So why the lag?

The Tegra 3 CPU is linked to the GPU, therefore, the GPU will only scale up to its maximum frequency if the CPU has activated multiple cores and is running at a high clock speed, however to save battery life the Tegra 3 prefers to use 1 core. This is why most Gameloft games lag (as they only use 1 core). Fortunately there is a fix, you can allow the GPU to scale dynamically by using the attached init.d script, if it doesn`t work, try using smanager, setting it to run on boot with su access. This will allow the phone to weight its processing more on the gpu, allowing the power hungry 40nm CPU to scale down to a lower clock, hence saving power. If you get stuttering in the UI make sure you flash a custom rom and enable the GPU 2d rendering or GPU UI rendering option in aroma.

Why won`t my phone scale to 1.7ghz all the time?/Why does my phone only use a single core when clearly more power is needed?

The Tegra 3 is also not a 1.7ghz quad core per say, the processor can only scale to 1.7ghz when using a single core. This is buggy as sometimes the processor will get stuck in single core and cause lag and unnecessary battery drain if the frequency scales too high in order to multitask. To fix this, head over to Nik3r`s thread and flash his elite kernel, hxore is also great however it does not include blades commits (however the removal of hotplug will give similar effects). These blade kernel implementations will allow the phone to use all four cores at 1.7ghz, dramatically assisting multithreaded applications and games that are cpu intensive but poorly optimized. To enable this use attached script.

My Launcher is constantly reloading/Heavy open world games lag/Sense multitasking sucks!

Elite also features swap memory, although I cannot recommend it for daily use, if you are a heavy gamer, it will help in any unity or unreal engine game and also stops the launcher from reloading which can be annoying (sense is a ram hog). These come in various sizes which from 128mb to 256mb and performance gains really depend on usage or what you think is necessary.

Performance is great but battery life is terrible

You might also want to try UV your phone,again poses some risk but cannot cause permanent damage like the aforementioned swap memory, before doing so check you tegra 3 chip variant. These range from 1-4 with the original One X being 1-3 and the One X+ being mainly 4, 3 if you are unlucky, the higher the better and faster/cooler. You can check by using a terminal emulator and typing:

cat /sys/kernel/debug/t3_variant

I personally own a variant 4 which operates well even with a 100 millivolt UV, however as all devices are different you will have to experiment with this. This option will keep heat down and save power as the tegra 3 has plenty of CPU to spare. I will also provide multiple UV Scripts for you to try out (stock elite is -25 millivolts). I also recommend using the phone in powersave when not gaming, the majority of games will probably run well even in powersave (limited to 1.15ghz and 3 cores).

Display uses the most power/auto-brightness scales too high or low/I just want to turn my button backlights off

You can also use a brilliant app called Lumos to manage screen brightness (the bright SLCD 2 screen does have its drawbacks) and backlight brightness or you can copy the lowest brightness apk from insertcoin v 3.2.1.

Developers aren`t releasing updates

Developers work for free and are devoting there free time that they could be spending on leisure, family or work to better our devices. They are not obliged to do this and release their work publicly. Most developers will listen to requests but please do not pester them excessively just because they see it unfit for implementation. please thank all developers for there hard work and even consider donating. A simple thanks is always appreciated, happy flashing.:good:

Update 1: New scripts!, seemed to have fixed a problem regarding the gpu failing to decouple, could explain why people were seeing no improvement. Custom folder if you want to tailor your device`s performance to your specific needs/rom/kernel, standard, just contains scripts that should provide a sizable performance gain for all devices.
