I've restored my old factory-OC settings and voltage (from EVGA no less) to test a DX11-related crash to see if Arma 3 suffers from it (considering its use of DX11 and known problems regarding low voltage), and found that it still happens in Arma 3. This is a known GPU-family-wide issue that happens on DX10 and higher (usually a DX11 problem now)
System specs before DXDiag:
Sandy Core i5 2500k stock
EVGA facto-OC GTX 570 (tested on both OC and non OC without voltage tweak)
There may be a need for a DX9 exe for those who are not aware of this rather prevalent issue for Geforce 500-series videocards, or something can be done on the Arma 3 end for this.
DXdiag will follow.
