How to separate speaker and headphone audio on Realtek?

Question

ASUS

I have an ASUS K56CB laptop with Windows 8.1.
After buying a laptop, the first thing I did was delete all partitions from the disk (including recovery, etc.) and installed a clean OS. After installing Windows 8.1, it turned out that the system installed its own sound driver (from Microsoft). In general, everything suits me, I will even say more - I like the driver from Microsoft much more than the driver from Realtek.
For example: better sound, the ability to separate speakers and headphones as two different devices, which allows you to configure them in your own way (your own volume level, your own equalizer settings) or output sound to a TV connected via VGA. By the way, speaking about the equalizer - it is not in the Microsoft driver, but there is such a cool option as "Loudness compensation", which allows you to make a very pleasant sound (which cannot be achieved using Realtek).
But there are a couple of disadvantages:
1. The sound lags in some games, for example, Battlefield 3,4, Hardline, and FPS sags during these lags.
2. Does not see the headset microphone (in K56CB, the input and output are combined into one jack, just like on phones)
I really do not want to sit on the Realtek driver - the sound is terrible, the equalizer, to put it mildly, leaves much to be desired. But most importantly, there is no way to use the built-in speakers and 3.5 output separately.
Google issues topics where this issue is solved tritely, for example, like here: How to output the sound of some programs only to a certain socket?
But in my case, I have such a Realtek dispatcher:
Are there any solutions to these issues?
