I'd like to give DCS a try, especially the helicopters to see if they fly more realistically than in P3D4.5. Take a look at my antiquated specs and see if I should even bother downloading the demo. Thanks in advance.

if you can  run p3dv4 .5  with no issues  than  you should  have  no issues in  downloading dcs  since its  free   with 1  scenery  and  2  or  more  aircraft  to try

It doesn't appear that DCS will run on anything under Windows 10 version,according to their website.
