Honestly, my system is 7 years old. All I've done is upgrade the Vid Card. I bought a GTX 1080Ti about 6 months ago. DCS only uses 2 cores. One for sound, and one for everything else. It uses GPU for gfx, and physics. So my poor system is like brand new now! I have settings about 3/4 right and get solid 30 FPS in even high density areas. Around Vegas it drops to about 28 but if I want Rock solid FPS just turn down the detail area.
