8192 x 4096 actually is supported by power of two hardware. The only
requirement for a TEXTURE_2D without NPOT abilities is that each
dimension (on its own) be a power of 2.
In general, something that might be worth checking out is the largest
free VRAM chunk via OpenGL Driver Monitor, since even with 512 MB of
VRAM allocating 256 megs for a single object is not necessarily a
trivial operation (ie make sure you don't try and allocate 2 of
them!) The fact that the texture halfway works, however, suggests
that the large allocation was successful.
Please file a radar with a small test case if this indeed turns out to
be the case, along with an attachment of your hardware profile that
can reproduce the issue.
Thanks,
Chris
