This is an experimental & incomplete feature for those using supersampling. Anything > 1200p will be downsampled by 50% before copying out of the GPU to save on memory bandwidth. Unfinished! Has issues with damage tracking and currently can not be configured. Only dx11 has been tested at this point, everything else will likely have problems/crash.
