I have been able to load textures into on of my commercial projects at a size of 4096x4096 with out resizing. I have the Ultra version of your graphics card so I dont know why it isnt working for you.
If you are loading a texture slightly smaller than the square for example 2047x2047 blitz will automaticly resize the graphic or texture then, but not if you make it a square value.
Hope that helped.
