How To Get Fallout 4 Running On A Terrible Old Computer

Fallout 4 isn’t quite as nice-looking as, say, The Witcher 3, but it’s not meant to run on fainthearted PCs either. It is, after all, gigantic.

Iyzik’s ultra-low graphics mod is meant to remedy that — at least, slightly. The mod pushes things like shadows, how far away you can see game world details, grass, and other small details well below the game’s lowest setting. The result? It’s not a huge visual change from low graphics settings, but you get a frames-per-second bump of five or so. It may not sound like a ton, but for many that’s the difference between playable post-apocalyptic romp and stuttering slideshow prison.

Here’s a video of the mod in action and an explanation of how to install it, courtesy of ZiggyD Gaming:

And here’s a longer one from TSM Channel:

If, however, that doesn’t make your wheezing machine breath a sigh of relief, bad news: this is (at least, for now) about as low as Fallout 4‘s gonna go. Iyzik explained:

“The majority of Fallout 4’s graphics settings appear to be ‘hardcoded’, i.e. we can’t change them. For example grass cannot be fully disabled, even if every reference that should disable them is set to disable. bAllowDrawGrass=0, bAllowCreateGrass=0…etc. None of it does anything. Textures also cannot be ‘skipped’ like they can in Skyrim. I’m not sure if that’s because mipmaps that low were just never generated for Fallout 4, or because its hardcoded to not do that.”

Bummer. Still, though, this is something. How’s Fallout 4 running on your PC?


    • At the risk of being “that guy”, try running the beta patch version if you aren’t already. Mine was crashing every 20 minutes until I changed to the beta build. YMMV, but I feel your pain at least… I’m always in a dilemma whether to go PC or console cause of those few games that seem to crash whatever you do….

      • Really? I’ve seen about 4 lock ups in about 4 days of play (according to my saves).

        There has been the typical Bethesda freeze that I got with every Bethesda game on xbox 360 (skyrim, fo3 and NV had this issue) but if you’re fast enough, just hit the middle button/white xbox symbol to take you to the dashboard and then hit a to go back in. Worked on the 360 by bringing up the guide, works on the x1 in the same way. Hope that helps, it’s saved my ass from a crash many times in fallout 4.

    • Yeah, I’m enjoying it on the PS4 at the moment because I’ve only had one crash in total after several days of play. But I’m really feeling the lack of mods. There are so many things I want to change. My next playthrough will be on PC.

  • 4gb ram and a 7850, I’m below min spec in some regards but running the game quite well 🙂 30fps/ultra but prefer lowering a few settings to get to get closer to 60 fps.

  • I get the occasional patch where frame rate will slow down but after a couple of minutes goes back to normal. Tried medium/low settings and neither of them make a difference so doesn’t seem to be tied to anything there. Guessing it’s some kind of bug in the way it handles things in the background, doesn’t seem to happen in any particular part of the map more than others.

    • For a while I was hoarding all looted armour, weapons, aid, and misc in separate lockers at my primary settlement. Hundreds of things in each of them.

      The game would crawl to a stop for a couple seconds any time I approached those lockers.

      • No issues for me yet at my loot chests…but I’m being reasonably brutal about what I bother storing vs just scrapping/selling/throwing away.
