Random fps drops at loading new tiles and super high CPU usage at Open World Areas

[Elemelepipi]

What happened to Warframe after recent hotfixes? 

I have not updated a single driver nor updated Windows. Suddenly game starts to drop from my 60 fps V-sync(i can't play without bacause of tearing)to ~50 for seconds.

Fps drops happens when something is loading to my screen(new tile, kuva siphon, joining players). What happened to the game code? And i saw in patchnotes some changes with Anisotropic Filtering changes to 2x(why?) I don't mind bugs but performance issues that are 99% on game side are driving me crazy.

My PC:

I5 6600k

GeForce 1060 6BG

RAM: 16GB from Corasir

 

 

I already made support ticket but noone is responding in 2 days.

Anyone else having trubbles?
