Fallout 4 on PC: Complete Setup, Settings & Beginner Guide (2026)
Fallout 4 is one of the most played RPGs on PC — and after the Amazon Prime Video series launched in April 2024, it broke records with nearly 180,000 concurrent Steam players and became the single biggest Steam sales spike for any game that month. If you just watched the show and want to experience the Wasteland yourself, or if you're returning after years away, this guide covers everything: download, system requirements, the Next-Gen Update settings, and a proper beginner walkthrough.
Can Your PC Run Fallout 4? (2026 System Requirements)
Bethesda released the Next-Gen Update in April 2024 (version 1.10.984), which added native 4K support, DLSS, AMD FSR, Intel XeSS, and over 1,000 bug fixes. The requirements below reflect that update.
| Tier | CPU | GPU | RAM | Storage | Target |
|---|---|---|---|---|---|
| Minimum | Intel Core i5-3450 / AMD Phenom II X4 945 | GTX 550 Ti / Radeon HD 7870 | 8 GB | 30 GB HDD | 720p 30fps Low |
| Recommended | Intel Core i7-4790 / AMD FX-9590 | GTX 780 / Radeon R9 290X | 8 GB | 30 GB SSD | 1080p 60fps High |
| High | Intel Core i5-10600K / AMD Ryzen 5 3600 | RTX 2070 / RX 6700 XT | 16 GB | 30 GB NVMe | 1440p 60fps Ultra |
| 4K/Ultra | Intel Core i7-12700K / AMD Ryzen 7 5800X | RTX 3080 / RX 6900 XT | 16 GB | 30 GB NVMe | 4K 60fps + Mods |
Important notes:
- An SSD is strongly recommended — HDDs cause noticeably longer load times in the open world.
- 8 GB RAM is the practical minimum. Heavy mod setups (100+ mods) commonly require 16 GB.
- The 30 GB figure grows significantly with mods and high-resolution texture packs (100+ GB total is normal for modded installs).
How to Download Fallout 4 on PC
Fallout 4 is available through three stores. The post-Next-Gen Update version is the same across all.
Steam (Recommended)
- Open Steam → Search "Fallout 4"
- Purchase the base game (~$19.99) or the Game of the Year Edition (~$29.99, includes all six DLCs — highly recommended)
- Click Install → choose your drive (SSD preferred)
- Download size is ~30 GB base, expanding if you install DLC separately
Xbox Game Pass for PC
- Install the Xbox app from the Microsoft Store
- Subscribe to PC Game Pass (~$9.99/month) or Xbox Game Pass Ultimate (~$14.99/month)
- Search "Fallout 4" in the Xbox app → click Install
- Note: Game Pass version has limitations with some mods (file write permissions in WindowsApps folder)
GOG (DRM-Free)
- Fallout 4 is not available on GOG. For DRM-free ownership of other Bethesda titles, GOG carries older entries in the series.
After installing:
- Launch once without mods to let the game generate configuration files
- The Creation Launcher will open — click Play to start normally or Mods to browse Bethesda.net mods
Best PC Settings for Fallout 4 (2026)
The Next-Gen Update added an Ultra Performance Mode and new upscaling options. Here is what each setting actually does to your framerate.
The Biggest FPS Killer: God Rays
God Rays (Volumetric Lighting) is by far the most expensive setting in Fallout 4. Unlike most games, "Ultra" godrays in this engine can cut performance by 30–60% vs "Low" with minimal visual impact at normal gameplay distances.
| God Rays Setting | FPS Impact |
|---|---|
| Ultra | -40 to -60% vs Low |
| High | -25 to -40% vs Low |
| Medium | -15 to -25% vs Low |
| Low | Baseline |
| Off | Not available (Low is effectively off) |
Recommendation for any PC struggling with FPS: set God Rays to Low first.
Full Settings Table
| Setting | Recommended | FPS Impact | Notes |
|---|---|---|---|
| God Rays Quality | Low | ★★★★★ | Biggest single lever in the game |
| Shadow Distance | Medium | ★★★★ | Ultra adds 20–30% load for distant shadow detail |
| Shadow Quality | Medium | ★★★ | |
| Ambient Occlusion | HBAO+ | ★★★ | SAO is cheaper, HBAO+ looks better |
| Depth of Field | Off | ★★ | Personal preference; off for combat clarity |
| Motion Blur | Off | ★ | Almost everyone disables this |
| Anti-Aliasing | TAA | ★ | TAA for sharpness; FXAA if you dislike TAA blur |
| Anisotropic Filtering | 16x | Negligible | Always 16x, no performance cost |
| Texture Quality | Ultra | Negligible | Keep on Ultra — VRAM limited only on 2 GB GPUs |
| Object Fade | 75% | ★ | Lower reduces pop-in at cost of visual range |
DLSS / FSR / XeSS (Next-Gen Update)
Added in April 2024, these upscalers are now in the base game:
| GPU | Recommended Upscaler |
|---|---|
| NVIDIA RTX 2000+ | DLSS Quality |
| NVIDIA GTX 10/16 | AMD FSR Quality |
| AMD RX 5000+ | AMD FSR Quality |
| Intel Arc | Intel XeSS Quality |
| Any (budget) | AMD FSR Balanced |
Access via Settings → Display → Upscaling Method.
FPS Cap and Frame Pacing
Fallout 4's engine has a physics bug tied to the framerate: above 60fps, the game's physics simulations break (doors explode, NPCs fly, items launch off tables). This is a known engine limitation inherited from the original release.
Solutions:
- Enable V-Sync in-game (locks to monitor refresh, which is fine at 60Hz)
- Or use NVIDIA/AMD frame limiter set to 60fps
- Or use the Uncapper mod (High FPS Physics Fix on Nexus Mods) — this allows 120fps+ with proper physics decoupling
Common Fallout 4 PC Errors and Fixes
| Problem | Likely Cause | Fix |
|---|---|---|
| Crash on startup | Missing Visual C++ redistrib. | Install VC++ 2019 Redistributable x64 from Microsoft |
| Stuttering / FPS drops in open world | Shadow Distance too high | Lower Shadow Distance to Medium |
| Long loading screens | HDD instead of SSD | Install to SSD; also check: iPresentInterval=1 in Fallout4.ini |
| Game won't start (black screen) | Fullscreen exclusive issue | Set Borderless Windowed in launcher, or add -fullscreen launch flag |
| Mods not working | Wrong load order | Use Vortex Mod Manager (auto-sorts LOOT order) |
| Creation Club content missing | Download incomplete | In-game: Extras → Creation Club → re-download each item |
| ENB / reshade dark screen | GOG rays / HDR conflict | Check ENB compatibility with Next-Gen Update; many old ENBs need patches |
| Very low FPS even on capable hardware | iPreloadSizeLimit too low | Add iPreloadSizeLimit=1073741824 to Fallout4.ini [General] |
| Game crashes after long sessions | Memory leak | Known engine issue; Buffout 4 mod (Nexus) fixes this |
Fallout 4 Beginner's Guide
The S.P.E.C.I.A.L. System — Make This Choice Wisely
At character creation, you distribute 28 points across seven attributes. These cannot be changed outside of items later in the game, so the starting spread matters.
| Attribute | What It Does | Beginner Priority |
|---|---|---|
| Strength | Carry weight, melee damage | Medium — 3–5 is enough early |
| Perception | VATS accuracy, lockpicking perk unlock | High — 4+ for Rifleman perks |
| Endurance | Max health per level | Medium — 3–5 |
| Charisma | Settlement size, persuasion, companion bonuses | Low — 1–3 is fine unless role-playing |
| Intelligence | XP gain per kill | High — INT 6 for Gun Nut (weapon mods). INT 5+ = faster leveling |
| Agility | VATS AP pool, action point regen | Medium — 3–5 |
| Luck | Crit chance, perk synergies | Low to Medium — 2–4 |
Beginner recommended spread: S3 P4 E3 C1 I6 A5 L6 (total 28) This gets you: Gun Nut at level 1 (weapon mods), Rifleman early, good VATS AP, and a high Luck for the Idiot Savant perk (+3x XP chance — powerful for fast leveling).
First Hour Priority List
- Complete the Vault 111 tutorial — do not skip it; it teaches the crafting UI
- Pick up every item in Sanctuary — even junk is crafting material
- Talk to Codsworth and head to Concord (quest: "When Freedom Calls")
- Rescue Preston Garvey in the Museum of Freedom — this unlocks settlements
- Grab the Power Armor frame on the museum roof — wear it, kill the Deathclaw
- Return to Sanctuary and build a basic settlement (beds + food + water + turrets)
- Head to Diamond City — it's the main hub and unlocks most companion quests
VATS (Vault-Tec Assisted Targeting System)
VATS slows time (not freeze in Fallout 4, unlike Fallout 3/NV), lets you target specific body parts, and uses Action Points (AP). On PC with mouse aim, VATS is less essential than on controller — but aiming at legs to cripple enemies, or weapons to disarm, is a strong tactical use even at full speed.
The Affinity System
Every companion gains or loses affinity based on your choices. High affinity unlocks their personal quest and a permanent perk. Key companions for different playstyles:
| Companion | Best For | Perk on Max Affinity |
|---|---|---|
| Dogmeat | Early game (no affinity penalty) | N/A (bonus with Lone Wanderer) |
| Piper Wright | Exploration + role-play | Gift of Gab (2x XP from speech/discoveries) |
| Nick Valentine | Hacking builds | Close to Metal (+1 hacking guess, faster reset) |
| Cait | Combat / raider RP | Trigger Rush (AP regen when health low) |
| Codsworth | No preference; generic | Robot Sympathy (+10 damage resist vs robots) |
| Strong | Melee / chaotic | Berserk (+20% melee at low health) |
Factions — The Point of No Return
Fallout 4 has four main factions: Railroad, Brotherhood of Steel, Institute, and Minutemen. You can complete the early quests of all four before committing. The quest "Mass Fusion" (Institute) or "Precipice of War" (Railroad) forces your hand — completing one locks out others. Keep manual saves before these quests.
DLC Guide — What's Worth Playing
| DLC | Setting | Recommended Order | Highlight |
|---|---|---|---|
| Far Harbor | Island off Maine coast | Level 25–35 | Best-written DLC; dark, complex story |
| Nuka-World | Raider theme park | Level 30+ | Large open world; best for evil playthroughs |
| Automatron | Robot DLC | Level 15+ | Lets you build custom robot companions |
| Vault-Tec Workshop | Settlement DLC | Anytime | Build your own Vault |
| Contraptions Workshop | Building DLC | Anytime | Complex conveyor belt systems |
| Wasteland Workshop | Settlement DLC | Anytime | Cages, arenas; niche |
Game of the Year Edition on Steam includes all six DLCs — buy GOTY rather than individual packs.
PC Modding Guide
Fallout 4 has one of the largest modding communities of any PC game. Nexus Mods (nexusmods.com) hosts 50,000+ mods.
Step 1 — Mod Manager Install Vortex (Nexus Mods official manager). It auto-handles load order via LOOT and resolves conflicts.
Step 2 — Essential Mods
| Mod | Why Install It |
|---|---|
| Unofficial Fallout 4 Patch (UFO4P) | Fixes 800+ bugs Bethesda never patched |
| Buffout 4 | Crash logger + engine fixes; nearly eliminates random CTDs |
| High FPS Physics Fix | Allows 120fps+ without physics breakage |
| Full Dialogue Interface | Restores the full dialogue options (not just "sarcastic/nice/neutral/no") |
| Sim Settlements 2 | Completely reworks the settlement system; feels like a DLC |
| True Storms | Realistic weather system with actual thunder, lightning, heavy rain |
| Place Everywhere | Removes settlement building restrictions |
| Boston FPS Fix | Reduces the notorious performance drop in central Boston |
Step 3 — ENB (Visual Overhaul) ENB presets rework lighting, color, and shadows dramatically. Popular: Rudy ENB, NAC X (Natural and Atmospheric Commonwealth). Requires ENBSeries base installed first.

FAQ
Is Fallout 4 free to play? No. The base game costs ~$19.99 on Steam, often discounted to $4.99–$9.99. It is included with Xbox Game Pass for PC (~$9.99/month). The GOTY Edition (~$29.99) includes all DLC and is the best value.
Does Fallout 4 work on Windows 11? Yes, fully compatible. The Next-Gen Update (April 2024) specifically improved Windows 11 stability.
Can I play Fallout 4 without the DLC? Yes. The base game is complete. Far Harbor and Nuka-World add 10–15 hours each; the Workshop DLCs add settlement building features.
Is the Next-Gen Update required? It's installed automatically via Steam. You cannot opt out on PC. The update added DLSS/FSR/XeSS and performance improvements, with some trade-offs for specific ENB/mod setups (check Nexus Mods for compatibility patches).
How long is Fallout 4? Main story only: ~25–30 hours. Full completion with all DLC: 100–150+ hours. Modded playthroughs can easily exceed 200 hours.
Is it worth playing in 2026? Absolutely. The modding scene is more active than ever following the Amazon show. New content like Sim Settlements 2 adds depth that rivals a full sequel.
Can I transfer my Xbox/PlayStation save to PC? No — save files are platform-specific and not transferable between PC and console.
What's the best faction to join? The Minutemen ending is the most morally flexible and does not require killing any major faction. The Institute ending unlocks the most unique late-game content. Railroad is best for roleplay if you care about synth rights. Brotherhood of Steel is best if you want military aesthetics and heavy weapons.
