Here are a couple of FPS tests

 

Disabling the NPCs in the level gives a large FPS boost (with and without the fog of war, the extra FPS is about the same). It's not the AI code that is contributing the FPS drop as I used a separate command to disable the AIController of every NPC in the level and it did not increase FPS.

Ha, that's bonkers what a huge increase.

Well, without the npcs, its basically just a large picture you are panning.

My experience with betas in general is also that the final product is always less choppy, for various reasons.

Forgot to mention that the disable AIController part in the second video still turned off the NPCs, and the command was recently replaced with a newer one that didn't remove the NPCs and disabled their AIController, which had no impact (and is not shown in the video).
