@MitoTakatori,

Thanks to
@jskasia for his help, I will soon create a thread for my modification of v20h. It'll look completely stock, only LG's stock font Foxrain will be replaced with Roboto Condensed, which is one of my favorites, and there will be Dual Window for all apps. I have only worked on performance and heat reduction and reached a quite agreeable point.The phone now has a stable and smooth performance and the amount of the heat it produces has been significantly reduced. I checked this after ~1 hour of gaming.
The ROM will also support 60fps FHD video recording, and photo capture quality will be increased to 100%.
@jskasia, C2D, which is set by default on all stock images, is "Core 2 Duo" screen rendering, which is a collaboration of the CPU and the GPU, with more emphasis on the latter. GPU is obvious. But as per MDP, it appears to depend on hardware support, which happily the G4 does. It probably puts less pressure on the CPU, so it doesn't heat up, and hence doesn't reach high thresholds, and this way, it won't decrease in frequency.
Oh, and why do you call my mod "the great combination?"

I'd rather call it "Pyrophag," meaning Fire Eater, the name I'm gonna put on my ROM.
BTW, you had asked about the camera config files I posted earlier; if you replace them with the stock ones, you'll get what I just described above. I looked into the 60fps camera mod that requires root to see what it actually does, and I did that to the stock files without removing Slow Motion recording mode, which that mod does.
