My PC has such choppy graphics and frame rate. Is my GPU overheating?

I think it's Civ 6 being a Civ game.

However, for Sims 4 I heard that you need to enable a larger internet cache file since it needs to cache all the store assets.

Also supposedly there's a memory leak with names in Sims 4 and resetnames (in the menu) fixes it but not sure.
