    Yep, of cause drawImage() is always faster than drawString() with vector font.

    Video post #4 is using setFont("6x8",4) because it is much faster than using vector and with option true no clear is needed, so this is similar to drawImage().

    • drawImage() can benefit of spi_send_many
    • lcd.setFont("Vector",20).drawString() looks like it is drawing pixel by pixel.

    My conclusion:

    • use drawImage when using vector font
    • split your screen in small sections and use drawImage to update them
