I don't know if there is already a Q&A for this, and I missed it.
Is there a way to have Magic seeker and Gun "snake" at the same time on the HUD, as an ACM mode?
First, 24000ft it's rather a medium-high altitude. And also does it seems to you natural, even lofting, to reach 63000ft at 1600knots, without the motor engine burning too long?
In my case, I had no problem logging in, and no crashes after.
Just a thought, if it helps with the problem.
Do you, my friends, start DCS as an administrator? Maybe it's important for this issue.
