Warframe has become nearly unplayable for me after the 8GB technical update, with massive frame drops every few seconds, going from 144 to even 3. It even happens in the orbiter, but after i visit all the rooms, it seems the game loaded everything up and then it starts to run normally. It's present in all missions, even linear ones, more so in the open world areas and more populated relays where even turning the camera causes frame drops.
I have the game set on directx 11, tried on 12, no difference. Tried verifying and optimizing cache, nothing changed. I have an i5 8600K, gtx 1060 6GB,
