So basically if you play heavy games on your device they tend to lag from time to time...
Well I have been using this application called
'ZRAM settings' it is very old
You just have to enable zram and a couple of other stuff as seen in the screen shot



Most of it functions actually require root
But enabling zram doesn't

After using it my phone doesn't over heat at all
Now I play games or run apps that demands upto 1gb ram without overheating issue and the game never lags only stutters which is due to obvious glitches from the game

You can try it... It is only about 500kb in size ;DD

After following the steps in the screenshot.. Simply reboot your phone

You can increase the read ahead size and tick 'kernel rampage merging'
Nothing else... Although those two are kernel selective

or you can simply swap it for a higher device with little change
