While I agree they should add better UI scaling, a large chunk of gamers won't be even thinking about 4k til the NEXT Generation of consoles at least since ps4 and the One still have issues achieving 1080p in general. Over the next couple years it will be easier and cheaper for pc gamers to switch to 4k but as of right now I say with at least the next couple years only the hardcore enthusiasts will go for 4k. Running 4k with a good frame rate on a single card right now is laughable at best. Sure you can achieve it and play it but you won't be getting that good of frames. Doesn't help that this game isn't even that well optimized for pc still.
