I’m starting to believe that Nanite was intended for Virtual Production and not games. I’ve noticed a lot of the engine has a better focus on virtual production & cinematics than Realtime performance and functionality.
I’ve been fighting with nanite for some time now and even digging through the source trying to find ways to optimize it for a 1080ti. Lumen works great on that card but nanite and VSM are the killers. It’s just not something you’ll want to use outside of virtual production.
Nanite is the reason why no matter what settings you use for other graphics features, the frame time remains stagnant. You can get better frame time’s with Nanite using r.Nanite.MaxPixelsPerEdge 8+ but this just makes using nanite uglier than LOD’s.
