ini file and found two in the My Games\Fallout 76, including Fallout76Prefs.ini, which has an iPresentInterval setting that allows you to unlock the framerate, with some potential side effects. None of these are really graphics settings, but they affect the UI and can be changed as you see fit. HUD opacity: Slider (0-100 in increments of 5)

Show active effects on HUD: All / Disabled / Detrimental These could have a slightly larger impact with a slower CPU. Grass fade: Slider (0-100 in increments of 5)Ĭombined, setting all four of these sliders to minimum caused less than a 1 percent improvement in performance. Object fade: Slider (0-100 in increments of 5) Item fade: Slider (0-100 in increments of 5) Going from high to low boosted framerates by 7 percent.Īctor fade: Slider (0-100 in increments of 5) Dropping from ultra to low improved performance by about 4 percent. Shadow quality: Low / Medium / High / Ultra. This is the single most demanding setting, and performance improved by around 12 percent at low quality. Not surprisingly, we saw no significant change in performance when setting this to low. Our test area didn't have a lot of water, which holds for many areas in the game.

At 4k ultra, the maximum VRAM used is about 5.5GB (barring memory leaks). At 1080p, low texture quality uses around 2.0-2.5GB VRAM, medium uses 2.5-3.0GB, and high uses 4.5-5.0GB. For cards with less memory, this may have more of an impact. Dropping to low had almost no effect on performance, at least with a GTX 1060 6GB.
