I have a 2 year old i7 4 GHz , 32GB 1333 and a 1080GTX with 8 GB , 2x500GB SSD RAID with a M2 250GB for TEMP files (Photoshop swap disk) and could not make DCS run at all.
for my skin making work, even that is not enough Photoshop really needs all that , I am surprised that DCS now needs that much as well, if not more.
the truth is that for the average PC flight sim enthusiast, DCS is becoming too expensive to run.
