I have this wierd error and I have no idea how i got it.
It all started when I tried to make own Zeus mission in editor or after update?!
In editor i added modules that need to start Zeus and it all worked good except that when I started I looked up in the sky, to fix that I needed to press the Zeus key or get back to editor and preview again.
The day after when I was going to join my own dedicated server on Windows 2008 I got the same issue when I join as Zeus, I start and is looking towards the sky or the screen is blank/black (I still se the dev version down right).
If I manage to fix this by disconnect and connect again I then can join Zeus. Here comes the strange part, when it do work I have an FPS between 6-10?! if I press esc and to get menu I get FPS locked on 60 and it is like it should be, press esc again to get back to Zeus FPS gets down to 6-10. This is not related to my dedicated, this happends when I join internet servers also. Also when mission starts I get a klick sound on my speakers and there is no sound, or they are talking in slowmotion???.
Another strange thing here, when I then try Zeus by starting my own MP server on my computer then It works like it should and also if i start Zeus in editor?? {F23425}
