Laptop stutter when switch tab while gaming after installed Bitdefender

Hi All,

Since i've installed Bitdefender and switch to gaming profile, I can't really switch to other task/window while gaming and become stutter. I always switch to internet browser to overcome my boredom of playing the game for 5 mins.

Then I uninstalled the av, still stutter when switching. Do I missing something? Also I noticed that my gpu and vram parameter on MSI Center is always on 9000mhz when idling. Already DDU my GPU driver, and reinstall my MSI center but the problem still presist.

Can anyone help?

Thanks.
