Hi Prathamesh11
I am Dave, I will help you with this.
Your version of Windows 10 is over 1 year out of date, while there is no guarantee that updating your system to 21h2 will solve this FPS drop problem, it is honestly the best thing to do, because the newest Intel drivers would target that latest Widows10 build.
Click the link below, then click 'Update Now' on that page to download the Update Assistant, then run that to immediately get 21h2 and bring your PC right up to date
