There are three things I find ball aching about DCS and they are how poorly optimised the code is. For the level of graphics it supports modern cpu's and gpu's should breeze through it but can't.
The map! Or rather, the map . It's more than ten years old and looks it too. Hopefully, sometime in the not too distant future, both these things will be addressed by this EDGE thing...thingy...er....
Oh yeah, thirdly; the ritual of the "setting of the controls" aaaaaghhhhh.
Other than that, its fine and I reserve it for my enjoyment of propellerless flying.
