High Framerate (240 FPS) explorations

Suppose we had a scenario where we had to render a Metahuman at 240 FPS on a 2K image, and our hardware budget was no issue.
It’s an interesting problem that I’ve been digging into over the past few days, and you can get pretty high up there already, around 200, with some major cuts.
I’m debating things like Forward vs Deferred, cutting back as much draw calls as possible, bone weights vs morph targets, everything really that I can think of.
Has anyone else had explorations in high frame rate projects? What were some of the things you ran into?
