[ALL ROM][4.4+] How to Completely Reduce Lag - Galaxy Grand Prime General

I already discussed this on the Prime thread, but I'll just post it into a new post for everyone.
This will also enable "Android Go Mode" on Android Oreo and above!

Skip to the second post if you just wanted the entries.
After an extensive research on how Grand Prime's Stock ROMs doesn't lag too much, I seem to have found the answer.
Samsung was able to get away from the lagging by adding this entry to the build.prop of the stock Grand Prime:
Code:
ro.config.low_ram=true
This entry sets the ROM to detect that the device has low RAM and thus, keeps background processes to a minimum. It also reduces system animations and visual effects. This is a standard with all Android builds (starting with 4.x), so this will work even on an AOSP-based Custom ROM.
Fun fact: This is also L Speed's "Low RAM" setting.
This works fine on most ROMs, especially TouchWiz ROMs running Android 5.0.2 and 5.1.1-based, and enables "Android Go" on AOSP Oreo ones. But the situation is different on other versions of Android before 8.0.
It completely disables SystemUI tinting. So it means that the status bar wouldn't be tinted, even if the app supports it.
It will also disable Google Now on Tap (on 6.0+) and Google Assistant (on 7.0+). The Assistant Go app can be installed, but only works on Oreo.
It disables lock screen wallpapers on TouchWiz ROMs running Android 6.0+, and AOSP ROMs running 7.0+ (Prime and Miix are unaffected). This also makes the Samsung Launcher crash on Samsung Experience (running Android 7.0+) ROMs. Again, Prime and Miix are unaffected.
But fortunately, this re-enables SystemUI tinting starting 5.0+.
Code:
persist.sys.force_highendgfx=true
This also works on 7.x ROMs, too. But this would never work on KitKat. The Google Asistant (or Now on Tap), though, wouldn't be re-enabled.
Few tests also shown that this entry caused more lagging. So add it at your own risk.

How to do this?
Simply add these entries to the build.prop of any ROM you wish to reduce the lag.
Code:
# Go Mode - HybridTeam 20180406
ro.config.low_ram=true
# Unquote at your own risk. Re-enables SystemUI tinting
# persist.sys.force_highendgfx=true
It's preferred to add it on the top, just after device information props (few ROMs, especially TouchWiz ones, has the same entry, though set as false).
Tell me if it works for you or not below!

Code:
# Sets device as low-RAM but still enables SystemUI tinting - HybridDevelopers 20170730
ro.config.low_ram=true
persist.sys.force_highendgfx=true
This better works if you put it after RIL/Stagefright entries.

It's just the preffered location. You can put it anywhere.

So i can put it below ro.pip.gated or qemu.hw.mainkeys=0?

Yep. But just make sure that a similar entry doesn't exist at the top, for this will not work.

Updated for new updates on these entries, and Oreo compatibility!
