I am currently working on a UFC clone for F/A18, in which I used 5 0.91 inch OLED with I2C and one 2.08 inch OLED with SPI. The FPS on the displays are not good, with U8G2 set to full-frame mode and modifying the bus clocks of I2C and SPI, the best I can get is around 5-6FPS. The major bottleneck is processing time on the MCU. With a high clock speed of STM32, there will be a great FPS boost.
