First, don't use userbenchmark, it's a website that spreads a lot of misinformation about pc parts, with a lot of biased content and agressive wording towards components that arent intel. Second, it's something with some specific spots in the game where there are lots of light sources and elements in the skybox, or a lot of cpu heavy loads like network sync, enemie ai and such, like on trostland's church and the shard of the traveler behind, titan's arcology, some bigger gambit maps as in gambit both maps are always rendered. Nothing has been done about this since launch, but newer areas like the dreaming city and the moon offer better overall performance.
