High poly CC is CC which is very detailed, it has a high number of polygons. For example an EA table may be only 200-300 polys whereas a CC table may be well over 2,000 - 8,000. You need a good dedicated graphics card in a computer to handle high poly CC. Your graphics chip is fairly old which is why your game lags. Could you provide a few links to the CC you use so I can check it out?
@BluebellfloraHi, here are some CC links.

The creator of the Buy mode furniture didn’t have a separate link to their CC, but i get most of my furniture CC from them.
I was a bit confused with what you meant, so just in case I included some CAS CC.
MXIMS CC items are lovely but some are high, not all though. You need to just cut down on the CC if you don't want lag. The Intel HD 4000 has never played the game really well unfortunately.
