If you generally run your system at 1980x1080 resolution, than No Man's Sky is supposed to detect that and run in the same resolution. Unfortunately, there is a bug that will cause No Man's Sky not to run in your native settings. This mod is a collection of files designed to fix the problem for just about any resolution. After all, the game shouldn't downgrade the experience if your machine is capable of running it.
