Obisdian’s Fallout: New Vegas might be the best of the Bethesda-era Fallout games, but it still got dragged through the ugly hedge backwards a dozen times over. There’s no higher resolution, sharpened texture pack or post-process filter in the world that can save this pudding-faced monstrosity from its blobby brown fate.
Time for extreme measures. E.g. getting a neural net to re-texture the entire game with feverish new auto-generated assets, devised by insane software after it was fed a broad selection of real-world paintings. I have never wanted to play a latter-day Fallout game more than this.
