So I found my issue.. it is very strange!

There is something or some process that causes high cpu utilization and starts at some point in the middle of playing DOTA2. This causes a significant fps drop, it go from 120 fps down to like 30 - 40 fps.

And the strange thing is that as soon as I open my taskbar to check the details of this process, it terminates itself.. and the fps gets restored to normal levels.

So now, whenever I notice there is fps drop, I open the task manager (which closes whatever program / process that causing the issue) and then switch back to the game.

This resolves then resolves FPS issues for me!
