How to run 4000 leds

Questions
1

Hello, total nood here.

I want to run around 4000 leds on wled. My plan is to run the leds in 8 channels of 500 leds each on a singel esp32, but im not sure. Than i would be cpu limited to ~18fps. So my questions are:

If i use 2 esp32 synced will the speed increased to ~35 fps, or does 1 esp32 do al the calculations so it woud not make a difference?

Or can i use something like a Falcon F16 v4 to drive the leds and only use te ep32 for the wled interface and home assistant integration, For an increase in performance?

(sorry for bed grammar not my first language)

Here’s an example of a similar attempt: Bunch of LEDs. Not quite up to the level you’re asking about, but same order of magnitude. The power considerations remain as well.
FPS remains limited when syncing, but a single ESP32 is likely good for what you’ve described.
If you’re thinking of a 2D display type setup, that may have other considerations.
