Yep.

Also note that the maximum size that an OpenGL implementation is required to
support is only 64 x 64. (Though most support more; the limit for any
destination object can be found using the GetDeviceInfo method, keyword
MAX_TEXTURE_DIMENSIONS.) The new TEXTURE_HIGHRES keyword in 5.5 lets you
exceed MAX_TEXTURE_DIMENSIONS, but it is incompatible with TEXTURE_COORD.
Aaaaaaarrrrrgggghhh!!
