Hey guys,

So a few weeks ago (4-5 maybe) suddenly my FPS in game dropped from around 100 to 14-15. I had a few days in which they -the FPS- returned to "normal" without any explanation, but the last week every time I try to play I get those 14-15. Even the main Dota 2 screen is super slow, taking about 3-5 seconds -or more- to load when I switch tabs.
My PC is:
- Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz 2.59 GHz
- 16 GB RAM
- GTX 1660Ti

I only use this PC for Dota 2 and I've been trying to find an answer in different forums but so far no luck... please help me out!
