Probably the max d3d texture size?

Someone sent tests a long time ago that showed that the max ddraw
surface size is 65535 for sysmem (and presumably HW if the HW limit is
beyond this in d3d8+).

At some point you'll hit the 2G address space limit. There's also a
chance that even if enough address space is free it is fragmented too
much to support your texture.
