Hots stuttering lag (hots only problem)

I’m experiencing stuttering lag on my hots games. This is an hots exclusive problem (every other game I play works fine - this is the only blizzard game I’m playing at the moment). If I play try mode everything is fine. I’m playing with a gaming pc (here you can have the specs:
GPU AMD Ryzen 7 3800X 8-Core Processor 3.89 GHz
RAM 16,0 GB
64 bit
Asus elite CPU)

a wired connection (running at 50 mb/sec in download)

and I’m really incapable of playing the game, especially at peak hours.
This morning till 2 pm everything was fine then the problem came back (problem that is even worst late in the evening, in fact in some games I dc).
I’ve used ‘Looking Glass’ tool and here u can have the results, please help me out! I don’t really want to quit the game because my best friends are on it, but I really CAN’T play in these conditions.
