Performance issues on non-DLC maps?

having been testing some of the maps, i’ve been having some slight performance and that troublesome sound issue on maps that came shipped with reach back during the 360 days, like Boardwalk, Powerhouse and with Forge World being the most severe, though maps from DLC like Anchor 9, Ridgeline and Highlands for example i experience much less or no performance issues. anyone else getting this pattern?

Yep forge maps give me performance issues. Very annoying as the rest are pretty much fine
