I am currently trying to decide if I should wait for the new ESP32-S3 for one more more upcoming projects or looking for something else. Beside of the higher number of I/O pins compared to the current ESP32 I would need some improvements when it comes to the read/write latency. I assume that the ESP-S3 will like the ESP-S2 support dedicated GPIO?

I understand that it can only be activated for a limited number of pins but that would be good enough. Unfortunately I was not able to find any statement how the performances of this new feature compares to the regular GPIO access? Based on the API there is although support for interrupts. Can we expect latency improvements (pure assembler isr are fine) when using dedicated GPIO inputs compared to regular GPIO input interrupts?
Dedicated GPIO performances?
