Gaming performance issues?

Just purchased the new 1600$+ CAD Iphone 12 Pro Max only to discover major gaming issues while playing the usual popular games ( call of duty mobile, pubg mobile, space marshals 3 and more )
experienced sluttering fps drop bad gaming overall performances. Even on apple Arcade. Im bound to Apple for years now but its very frustrating and disappointing experiencing these issues with the 
“ world’s best Iphone Ever Made “

Is there a software fix solution coming soon?

Thank you.
