New SR: Whats up with the map texture? Low Res only?

Whats up. I play on High settings for all (shadows, characters, environment, spells).

Why is the new SR map so low res? Heres a screenshot of Nidalee on the new map. See those pixels on the floor that you can't see on nidalee? Why does the map look like a 500x500 image thats been stretched out to fit my screen? I wonder if Riot is thinking about 4k textures? You can see a notable difference between the Nidalee and the Tower, both of which look GREAT, then that floor...
