Sorry for late response, I never received an email about this bug for some
reason.

Why would libGL use system RAM for graphics processing? That makes no sense. In
addition, that statement contradicts how the bug behaves on my system, where it
has plenty of system RAM to work with (I have 4GB total, DAO only takes up
maybe 1.5GB at maximum, my background processes take up ~600MB), but still hits
GL_OUT_OF_MEMORY. The only logical explanation is its related to video memory.

It's very much possible that games are actually using the
GetAvailableTextureMem function to decide whether or not they should unload
something from their memory before loading something else in.

I tried lowering VideoMemorySize with another game and got numerous
GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT errors (and a nice little dialog box that
said "Out of memory!" that I couldn't dismiss until I alt-tabbed to the
terminal window and hit Ctrl-C, though I'm not certain whether Wine or my game
generated that).

Unless everyone else can use that method just fine and it's only me, I do not
feel comfortable with that being a recommended solution.
