Ie World of warcraft i use 2715x1750 ie or someting so 2x orginal HD resoluton and it down samples it to Full HD. Everyting is fine on that game for example, expect some font are more sharper.
But for this game it some reason dont downscale UI to full HD its like its in 2715 relolution (menus / text) etc. are really small, but Graphics look great.
by the way it actually works in Xrebirth too but i just could not use it cos getting 40-60 fps with antialiancing 2x without supersampling
