I would say you want at least 32g ram and a 3000 series video card (or AMD equivalent) with either a dedicated NvME drive or one big enough to run winblows, drivers and other stuff that is required to go on the C drive. My DCS folder is over 500g.
DCS can use all of your cores depending on how you start it up. When using multi-threading you can see bogies from beyond icon range which is 10 nm.
