Game freezes visually, but connection persists

[Moonfish]

Hi all! I've been trying to get P1999 working and have tried various installs both clean and Duxa's. What ends up happening is I can play for about 3 minutes or so and the screen freezes in place but I still have sound / can interact and use abilities. I still hear my character sitting if I click where the sit icon is, but I'm permanently locked in whatever happened in that moment visually. Hope that makes sense. Any advice is greatly appreciated it's been so long since I've played EQ I'd love to hop back in.
