Massive amount of artifacts in every single map.

During every single map i have this happening all the time. Its on the border of being unplayable and it can cover my whole screen in flashes of 0.5 seconds. I am 99% it is Headhunter causing this because it always starts when get a few buffs. I've tried deleting shaders, updating drivers and everything else i could find.

Have the same problem. Farmed some burials without beyond and it was totally fine, and now i'm having thoses same artifacts when I tried to put beyond on some maps.

The problem is most likely coming from the buffs we steal from beyond monsters.

Update or roll back your GFX cards drivers, while updating drivers is usually the best way to go it can have issues like new bugs any time there is a new update.
Personaly i've not actually upgraded my gfx driver in about a year.
