Low FPS

Hello I purchased the AOM Retold on steam, I have required hardware but I have 15 FPS during play.
In menu main menu I have 15FPS, after I click on campaign and there is mission selection I have there 60 FPS.
I tried lower every possible setting and resolution in game but there is no FPS change between HIGH and LOW settings.
I attached screenshot from hardware monitoring (max settings), GPU is at 25% and CPU 40-60%
I tried overclock the CPU to 4,1GHz but did not help

Do you have some advice for me where is the problem?
Thank you
