Nun fragt mich bitte nicht, warum das so ist, normal sollte das natürlich nicht sein.
Ich habe eine neue Version meiner Map kompiliert, auf einmal habe ich ein Problem in der Map.

Hier ein kleines Video, was mein Problem in etwa zeigt (Laggen und Lichtflackern)
http://www.file-upload.net/download-2754328/2010-08-17.AVI.html

Die Lichter sind auf Normal Einstellungen (also kein Appearance)

Dazu sei gesagt: Die Map ist sehr groß und vielleicht ein bisschen zu komplex, aber bisher hat sie problemfrei funktioniert. Und nun hab ich an einer Stelle etwas hinzugefügt (nur brushes) und jetzt macht es nicht mehr wirklich spaß dadrauf zu spielen ;D
Im compile-log finde ich, bis auf einige "VERY FULL's!" nichts auérgewöhnliches.

Vielleicht kann mir jemand helfen.
Ich hoffe, es gibt noch keinen Thread, der genau das beschreibt o.O
