Hey uhm i dunno if it is only me, but im sure others might be effected by it too, when im loading in the ttt, cause of the youtube video, its causing me to crash my garrys mod. I would figure its because of my computer but for a suggestion if possibly using pictures instead of the video so others dont crash.
Are all your drivers up to date? No one else has mentioned any issues as a result of it and the server is populated fine.
For me it plays like 2 seconds, then stops. Then 30 seconds later plays about 5 seconds then stops. It's basically just for new people to the server who have to download stuff and there to annoy you if you already have it.
It constantly changes due to the way net messages are sent in source. When you change level after playing it still has the current loading screen, then when it's sent a new message it refreshes the loading screen and plays again.
