Thank you for your reply. Sorry for forgetting the most important part about my setup. The Controller i am using, it is a NORA-W106 on a Arduino Nano ESP32 and according to its docs it has a clock speed of up to 240MHz, so i guess that would be enough depending on if that’s also base clock speed its running on right now…

NORA-W10 series modules have a dual-core system with two Harvard Architecture Xtensa LX7 CPUs operating at a maximum 240 MHz internal clock frequency.

Currently i set the SPI speed using SPI.setClockDivider(SPI_CLOCK_DIV2); Which would be 120MHz to my understanding assuming it runs at maximum speed. Too fast for SPI but that is not how it feels like. I will try some things out once i am back home especially as the method i use seems to be deprecated.
