Black Screen

"I see a black screen for about 10 seconds after loading the server (but before my character loads)"

It is normal for the anticheat to have a "weight" on your server, if the "black screen" lasts for more than 5 seconds the problem could be linked to one of these settings

Remove safe-events from resources linked to your multichar or basevents fg safe-events uninstall ResourceName
Remove objects-ai from resources linked to your multichar or basevents fg objects-ai uninstall ResourceName
Remove scr-prot from resources linked to your multichar or basevents fg scr-prot uninstall ResourceName
For some servers the problem is related to particles, so open your dashboard and completely remove the detections related to particles, you can find them in the particles category
