While I don't know whether the game itself is worth purchasing at all in the first place...if I am understanding the original message correctly, it's possible this applies only to 2D assets like menu or window textures and so on, not the textures used elsewhere, such as for the actual 3D character models, right?
Which isn't ideal, I get it, but that's still very different from what the title of the thread and several of the comments are implying (in other words, that all the textures in the game are 720p, or that the game simply doesn't support running at higher resolutions).
If I had to make a wild guess, I assume this sort of decision might be the product of a mix of PC piracy fears, performance issues and wanting to keep the console version as the more appealing choice.
