the concept of rendering the game at a much higher, custom made, resolution than your monitor is capable of displaying and subsequently having the GPU rescale the image ( as in downsample ) to that of your monitor's native resolution to which the end result is a "cleaner", sharper and less aliased image.
Well, my monitor displays only 1920x1080.
I've tried DownSamplingGui_0.6 with my Radeon, downsampling worked but "only" in 2560x1600

Then, I've discovered GeDoSaTo in a small downsampling topic on french forum canardpc.com
I've downloaded the last release GeDoSaTo Beta 10 Release – “Poltergeist” at official website : http://blog.metaclassofnil.com
Unzip the file, launch 2K14... fail
But after few tweaks, i achieve to run 2K14 (slowly) in 7680x4320 !




I let you try this fantastic tool.
I also share my (first light) config for 2K14, game runs smoothly in 3840x2160 with it.
And, feel free to share your config too, since you can add post processing effects directly in toGeDoSaTo
