Output with sprites or directly to the TFT??

[Blaubart]

I'm looking for the best way to display data on a TFT using an ESP32 and TFT_eSPI. You can see what this should look like here: https://freevario.de/wp-content/uploads/2024/03/Vario5.jpg

The colored bow has to adjust very quickly and the arrows have to rotate quickly in the background because they are supposed to show the relative wind of a glider as it circles.

Currently all outputs are pushed in a sprite, and these are pushed into a sprite "Background". The complete background is pushed onto the TFT at the end. This gives me a good display without flickering. Unfortunately, the speed is too slow and the arc builds up too slowly. It was therefore recommended that I set up the image in such a way that I first make the screen black and then push all output directly to the TFT. The speed is hardly better and due to the constant changing of tft.fillScreen(BLACK); and output of text or bow and arrow, the image flickers extremely. Which way makes sense and can still be optimized appropriately? Thanks for your tips!
