[Bug 40448] Final Fantasy XI: Missing character models, potential black screen and crashes

https://bugs.winehq.org/show_bug.cgi?id=40448

--- Comment #1 from Matteo Bruni  ---
I guess your GPU is not identified by wined3d so it ends up using a fallback
emulated GPU and video memory size. Probably the patch you mention makes the
game use just slightly more video memory in some instances which in turn causes
the issues you mention.

Setting the registry key VideoMemorySize
(https://wiki.winehq.org/Useful_Registry_Keys) to a reasonable value like 1024
should be a workaround for your issues.
WRT fixing the GPU identification, can you attach the start of a +d3d log when
running the game? I'm mostly interested in the "GL_RENDERER: " line.
