DraStic

I was wondering how hard it would be to enable higher rendering resolutions than the current "high res" 512x384. Right now I'm using a heavy 3x xbr filter to compensate but it definitely is not the best looking solution. Most of the argument i've seen against it is that it is too demanding on the CPU due to software based rendering. My Pixel XL has quite a bit of headroom with high res rendering enabled. I get that it's a high end device but phones are getting more powerful. Thoughts?
