Whenever the topic of texture page sizes comes up, there's a vague "if you use bigger texture page sizes, it might not be supported" answer given out.
Even the manual says this: "Note that the maximum size of a texture page will depend on the chosen export platform, as some targets will not permit pages larger than 2048x2048px, and even then, the maximum available size may not be optimal for all the devices that use the target platform OS."
But no one actually says what component of the system determines the max size of the image it supports. Is it the GPU? Where can I find out the size that a GPU supports?
Having a vague answer to this question isn't really good enough, because if someone has an incompatible system, they just won't be able to play the game at all. So finding out the answer to this question is important.
