POCO X8 PRO FPS DROP

So i have the poco x8 pro 12/256 indian varient a week ago but i am facing some issues in it . like when i play medium heavy like roblox . it runs fine for a few minutes like 57-60 FPS constant and then sometimes suddenly it drops to like 30-32 Fps ( stable btw ) , i dont think its issue with the hardware , i think its optimization's issue because when frame drops generally it should not be stable at 30 but in my case it was like for few secs then again it went to 57-60.
