Forge maps are terrible for us splitscreeners

My brother in law and I have been playing H4 split screen for awhile now since his box redringed. When we had been playing pre-red ring we had little to no problems with lagging. Now playing split screen the game is damn near unplayable if a forge map is selected. Has anyone (community or 343) found a solution to this problem?

I’m not sure what the cause is. The only thing I notice when we do split creen is that the render distance goes down a bit.

Single single online is fine. But as soon as player two signs in and load a forge map we lag terribly. It’s only forge maps too. I’m talking terrible frame rate, dropped textures. It’s bad.
