Shaders going crazy after today's patch, can't move in game.

We all know certain builds/areas in PoE can cause big fps loss. Things have seemed to be improving, like with the removal of trash items showing up on the ground. However, after today's patch when I enter a map - my shaders go to max. I don't even have to be fighting anything. I can barely move. If I stand still - shaders go back down. Take 2 steps, MAX SHADER BAR! Then I can't move.

Now bring mobs/abilities into the picture and the game is basically unplayable. I run on a custom built PC about 2 yrs old, Nvidia Geforce 1070 card, fps have been capped very low for ages because of issues like this/overheating that are a Path of Exile issue exclusively (even with upgraded cooling systems in my pc, this is the only game that overheats my PC and I run EVERY setting on LOW). Something in today's patch is making my shaders go crazy and the game is unplayable.

I can't move, I can't use a potion or ability, and this is just with trash mobs at the start of a map. Heaven forbid I tried the league mechanic after today's patch. Something is... very off. Every step my character takes, even with zero mobs on screen and zero abilities going off, my shaders max and I can't move.

Edit: I have run all diagnostic settings on my PC and tried playing the other games I enjoy. No problems anywhere else. Did not have this issue until today's patch hit.
