Some (general) tips to improve performance on Android (including the GPD XD) :
- I use mLauncher as my main launcher. It's perhaps the most lightweight launcher after Null launcher.
It should improve the CPU performance a bit compared to even Nova.
Plus, you can use your controller to navigate more easily compared to stock.
- Increase Entropy's reading and writing to 4096. (You can use Adiutor to change that setting)
- Change the scheduler to noop if you use an sdcard/nand. Change Read-Ahead to 4096kb. (Its in I/O Scheduler with Adiutor)

Also, here's another setting that can make a difference.
In Developer Options, enable "Don't keep activities" and set Background process limit to "No background processes".
You should only do this though if you don't use apps like Discord/Facebook and only play games, one at a time.

For games in general, the general consensus is : For static/simple 2D games, interactive.
For everything else, use the performance governor.
Powersave is simply going to be too slow unless you only want to watch videos.

As for emulators, you will most likely need to tweak the settings.
For PPSSP, i would recommend you make use of "game config" as it is called for each game.
But using "Skip buffer effects" instead off "Buferred rendering" is much faster and can look nicer. (or worse depends)

The I/O scheduler depends on the app, noop is faster for some processes. However, deadline is faster for some emus like PPSSPP or uoyabause. Difference is very minimal in XD between I/O schedulers, because all are configured in my kernel in a very aggresive way.
About PPSSPP, skip buffering break graphics in many games. Some work faster though, but pretty much depends on the game. Generally enabling multithread and disable block transfer gives a speed boost. Performance governor is also recommended to play some games fullspeed like Tekken 6.

About the launcher, the AOSP one of the rom is very lightweight (controller can be used too). I personally  use Smart Launcher Pro in Android. But that depends on personal preferences. Arc Browser is also very nice for those that use as a frontend.

About governors, for saving battery ragigmolasses included in my kernel is more battery friendly, but only recomended for non demanding emus, like snes, MD, etc... Interactive is more agressive in RK3288 in comparison to another kernels. It ramps cpu speed pretty fast, though for some apps like PPSSPP or uoyabause performance gives better result. Also in Adiutor you can disable cores to increase battery time since most emus just use 1 or 2 cores.
Anyhow, my kernel is in my github (check my rom's thread for the link), so anyone is welcome to improve, add things, etc etc... since I stopped development for XD definetely.

Oh man you guys broke my brain hehe.
Now that I have your attention, can you tell me if what I did in the tutorial will help people using 1.8GHz.
I just wanted noob users to be able to take advantage of 1.8GHz speeds with minimal risk as far as overheating.
Are those settings ok? or is there better settings as far as on and off?

Eventually I could make a better tutorial for better settings but I don't know enough about cpu clocking and whatnot, I'd have to get someone to write it.

Those settings in the video are fine for me. For noobs is enough, though if someone is very noob probably won't use cfw. Though those settings can be used in stock too (with root and no 1,8 GHz, but at least can learn how to use governor)

I think that is the main reason I make these tuts. Encourage the super noobs to see how easy it is to update Firmware to Stock or Legacy. If they ever decide to update their own Firmware, the process is the same, so why not. Meh we will see if they help out.
