I had dc issue as well when I had to zakum. My solution was gfx every zakum body is finished. How I did was: 1) Put highest graphic setting at the start 2) When all the armss die put the next lower graphic setting 3) When 1st body is finished put the next lower graphic setting 4) When 2nd body is finished put he next lower graphic setting which is the lowest. Hope this helps
It doesn't work to just leave it at lowest, you have to change it each time the arms or bodies change. Or use a Radeon graphics card.
