What is this nasty clone? Running at quarter speed!

I have some experience with the LGT8F328P board from WEMOS:

The LED is on Pin 12 (MISO) and the board is bigger than the original NANO V3 and has other layout (Pins,...).

I had made a DDS-function generator with an 1602 display and rotary encoders. Because of the 32 MHz the sine is going up to more than 20 kHz (Atmega328P about 10 kHz).

I have tested an ILI9341 SPI grahic display (240x320) . It was only going with ucglib:

not with adafruit gfx ...

ILI9341 is running also with UFTLIB (SW-SPI), but slow.

I have tested also the Nano LGTF328P clone ,

but with no positive results.
