Half resolutions screens save at... drumroll... half res! Actually did not know that. Though half res drops everything down to half res unsuprisingly sure but that includes everything including that giant red circle with the star in the middle which is looking pretty sharp from where I'm standing, or sitting.
So I'd have to go with nope, though the difference in picture was quite clear when I turned half res on and off again. Thanks for playing, at the very least you played when everyone else either didn't know or aren't bothering to help.
