Just to let you know....no matter what you throw at it FSX is never happy totally.
GTX980 ...32gig DDR4... M.2 Harddrive...i7 5960x ....
Might benchmark Res Evil 5 at an average of 250.8 fps [1680x1050 DX10]....
...but FSX is another story...
Holy crap! A GTX980? Well, I guess I could sell BOTH of my kidneys.
My GTX750 seems to handle DCS on its highest settings so far. The best I could reasonably consider right now would be a GTX970.
Had to bump my RAM from 8 to 16GB and ordered another 16 to be installed when it comes in the post. FSX graphics don't seem to be as realistic as DCS World so far, but that could be because I haven't downloaded any maps for either one.
I like both FSX and DCS so far.
