As we know, switching Mayhem modes causes the level to reload (except in Sanctuary).
My initial thought on this was that they pre-generate many (if not all) enemies and loot, and switching Mayhem required re-generating those things to match the new mode, health, gear, so on, and that’s it.
So, thought I with my programmer brain, switching modes should be faster than a load from the home screen, since you wouldn’t need to reload all the graphic assets for the map, just do in-memory deletion and recreation. Lots faster than hitting the disk, what’s called a warm restart vs. cold.
Decided to test it. Loaded from the home screen 5 times, and switched between M9 and M10 5 times, Xbox One S.
And no. Changing Mayhem is only 3-5 seconds quicker than a clean from home load, 50 seconds or so vs. 55. Which means (without instrumentation proving it) that they are in fact reloading all the graphic data on a “simple” mayhem mode change, which wastes time. I’d fix that…
On the plus side, doing this got me a Mayhem 10 Light Show with a “Action Skill Active” (which Zane almost always has) buff of 200% damage, which is pretty danged awesome.
