Playonline Viewer (the front end for logging into the game) does not draw properly with dgVoodoo2's DDraw.dll. The background draws but the text doesn't. Works fine without it and I don't think the actual game uses DDraw anyway but it's still an issue so I'm mentioning it. If you remove DDraw.DLL from POL's directory the game will load and run with just d3d8.dll
Fog is not applied to mobs, the best place to see this is in the Sanctuary of Zi'tah where there is constant fog and the trunks of the larger trees are actually mobs rather than part of the landscape (their branches are apparently part of the landscape geometry though, no idea why this is). This affects any moving object, ferries and airships, monsters, etc. Landscape fogs, anything that moves and some static elements like the tree trunks here do not. EDIT: And the outpost building too I just noticed.
Another oddity is that I have to put the DLLs in both \Square Exix\FINAL FANTASY XI and \Square Enix\PlayOnlineViewer so I need two copies of the DLLs in two different directories to get it to work.
EDIT: I just noticed that the large tree trunks and the smaller ones don't fog but the "medium" sized one do. Maybe they were working around some limitation with the engine here but apparently some of the tree trunks are part of the landscape geometry and others are not.
