than you for your help.
1.) Your hardware: I assume you are using your own (custom specific) hardware, correct? Let me know more details about the external SDRAM and the external Flash memory (type, size, configuration, performance).
SDRAM : MT48LC4M32B2B5-6AXIT

external Flash Memory : MT25QL512ABB8ESF-0AAT
https://kr.mouser.com/ProductDetail/Micron/MT25QL512ABB8ESF-0AAT?qs=rrS6PyfT74da2PZ8DoLIJg%3D%3D
is this information can be the answer ?
2.) Your display: What is the resolution in pixel of the display? How is it connected?
our display's resolution is 1024 x 600 and it's connected with I2C communication.
The configuration of I2C commu's speed mode is Standard Mode, Speed Frequency is 100KHz.
is this configuration could effect on CPU load or FPS ?
3.) Your configuration: Please let me know the entire console output that you get during start-up of the application. Are there further error messages?
I can't catch your exact intention, but I will attach my stm32cubeIDE build output log and embedded wizard build log. as you see, there are no errors.
in here I can't upload pictures more than one. I will put my blog to attach screenshots.

4.) Your application: Have you tried a simple animation (e.g. moving rectangle by effect)? What framerates and CPU load values do you get?
after I received your answer, I tried it. I will upload this video file on the youtube.

and I found that images that has a very big(bitmap code size is 10000 lines) bitmap size trigger high CPU load. is it right?
a big bitmap image and low i2c frequency has a correlation ?
also, if you see the video, FPS between dialogue change is almost 10 FPS. how can we handle this ? I mean, how can we rise FPS between screen change if we are in a low CPU load.
thank you for your help.
