See this thread, I've been on Teamspeak several times with clients who get this exact black screen when joining a server and this fixes it for them

Are you launching any mission beforehand or joining any other server before attempting to join our server?
If so you will get a red IC icon, you have to start DCS and instantly join the server and nothing else.
Try to boost your pagefile, see this post for example

If you have 16gb RAM and a decent SSD you should be able to join any server using this method.
Awesome, I recommend to everyone that you delete the those two folders fxo and metashaders2 EVERY time there is an update for DCS, removes so many potential graphical and performance problems.
Also you could try deleting the fxo and metashaders2 folders from your DCS Saved Games directory, maybe something left from an earlier version is clashing with the current one.
Completely stumped as to why you're seeing these anomalies, here's how the trees and hangars should look, the version in the first post was updated several days ago do you have that one?
The textures for this old version is long past being supported, see the current thread for the latest package

The 104th Dedicated also uses a custom autoexec.cfg serverside to allow optimal bandwidth usage, many servers do not and have problems as you describe.
You could try using a autoexec.cfg with customized network parameters like many other users have done, drop this into your Users\<name>\DCS\Config folder

or alternatively if you already have an existing autoxec.cfg you can add the following
if not net then net = {} end
net.download_speed = 12800*1024
net.upload_speed = 1024*1024
A little gift, I've been using this v1.20 for over a week now
https://drive.google.com/open?id=1LYXqcx7F1midRfmq6Rs6pK0YmXzown-J
it's an adaptation of that earlier v1.19 mod I trialed a short time ago.
This is completely unrelated to the files modified in the package, no shaderfiles are edited so I have no clue why you're seeing this.
Link was being updated, check first post now.
Pretty sure my mod doesn't affect aircraft shelters so this is strange, I'll go check.
edit: ok I see the problem now and it's fixed, updated link in first post (some texture file extensions had been changed in 2.5.4)
Download finally complete, towards the end it was hitting around 4-5mb/s so it did accelerate a bit, guess there were too many leechers and not enough seeders at the time :)
