In Valorant, Colorful iGame RTX 5080 16GB suffers from sharp frequency fluctuation in low-load scenes, how can this fluctuation be treated?

During precise sniping, a sudden drop in frames occurs without any prior warning, which is illogical for a powerful card like the 5080. Via the GamePP Hardware Sensor Page, I noticed that due to the low load of the game, the core frequency was jumping violently between 800MHz and 2100MHz, creating a fluctuation in frame generation time between 15-40ms. I first tried activating 'Maximum Performance' from the driver, but strangely, the frame drop rate increased despite the higher average, which made me handle the matter with extreme caution.
