To understand the chaos, you must understand F4SE (Fallout 4 Script Extender) . F4SE is a third-party tool that allows mods to do things Bethesda’s native engine cannot—complex hotkeys, better UI, and advanced scripting. Every time Bethesda releases a new .exe file for Fallout 4, F4SE must be updated to match the new executable’s signature.
Patch 1.10.163 changed the Fallout4.exe binary. Consequently, every single F4SE-dependent mod—from Place Everywhere to LooksMenu to MCM (Mod Configuration Menu)—stopped functioning instantly.
Patch 1.10.163 is not exciting for vanilla players. It added no new quests, weapons, or visible features. For the modding community, however, it is a sacred artifact—the last stable, well-understood, and fully compatible version of Fallout 4 before Bethesda’s disruptive next-gen patch.
If you see a mod on Nexus say “Requires game version 1.10.163 or lower,” you now know why. This patch represents the end of an era: when Fallout 4 modding was chaotic but mature, and when F4SE was the king of the modding castle.
Should you update to it? Only if you intend to build a classic, stable, massive mod list. Otherwise, stick with the 2024 next-gen patch or use a downgrader to go back to 1.10.163 specifically.

Fallout 4 Patch 1.10.163: Why the "Old Gen" Version Is Still Trending in 2026
In the world of Bethesda RPGs, a "new" update isn't always a welcome one. As of May 2026, despite the release of official Next-Gen and Anniversary Edition (AE) updates, the Fallout 4 patch 1.10.163 (originally released in December 2019) remains one of the most discussed and sought-after versions of the game.
For many players, 1.10.163 represents the "Gold Standard" of stability and compatibility. If you are seeing this version trending or being called "hot," it's because it has become the primary destination for players downgrading their games to escape the bugs and mod-breaking changes of more recent updates. Why is Fallout 4 1.10.163 Still Relevant?
While the Next-Gen update (v1.10.984) brought technical improvements like 60 FPS support for consoles, it also introduced several high-profile issues and broke thousands of PC mods. Patch 1.10.163 is the final version before these massive overhauls, making it the essential platform for:
Ultimate Mod Compatibility: Many of the most popular mods on Nexus Mods were built specifically for this version and never received updates for the Next-Gen or Anniversary editions.
F4SE Reliability: The Fallout 4 Script Extender (F4SE), which powers complex mods like FallUI or High FPS Physics Fix, is most stable on 1.10.163.
Total Conversions: Massive projects like Fallout: London rely on the 1.10.163 engine to function correctly.
Stability: Long-time players often cite this version as having fewer random crashes and better "fixed" performance once paired with the Unofficial Fallout 4 Patch (Pre-Next Gen). The "Hot" Trend: The Downgrade Movement
The reason this specific keyword is "hot" right now is the widespread use of Downgrade Tools. Since Steam and other platforms automatically update games to the latest version, players have turned to specialized software to revert their files.
In the community, version 1.10.163 is widely considered the "gold standard" for PC modding. It was the final stable build released in late 2019 before the major "Next-Gen" and "Anniversary" updates in 2024 and 2025 disrupted the modding ecosystem.
Because newer patches frequently break the Fallout 4 Script Extender (F4SE) and other essential mods, many players actively seek to "downgrade" their game back to this specific version. Why Version 1.10.163 is the "Hot" Choice

Title: The 110163 Hotfix
Log Entry: Vault-Tec Regional Server, Archive User "M1dn1ght_C1pher"
Date: October 23, 2287 (System clock discrepancy: +219 years)
It started not as an update, but as a temperature. Three weeks after the “Next-Gen” update of 2024, modders on the Nexus noticed a single, anomalous file in their load orders. It wasn’t an ESP or an ESM. It was a .hkx animation file labeled Weapon_Rail_Pump_110163.hkx.
No one remembered downloading it. Steam claimed it was part of Patch 1.10.163, a minor stability hotfix for the “High FPS Physics Fix.” But the file size was wrong: 1.1MB of standard animation data, but with a thermal signature of 42° Celsius—hot to the touch, even on an SSD.
The first report came from a user in Reykjavík. He wrote: “My character’s Pip-Boy light is flickering. Not stuttering—flickering. Like a Geiger counter. When it stops, I see a shadow in the corner of Sanctuary that wasn’t there. The shadow is holding a pipe rifle. The rifle’s bolt is pumping on its own.”
The thread was deleted within six hours. But the patch propagated.
I’m a data miner. Not a hero. I downloaded the patch’s delta files manually. Buried inside the Fallout4 - Interface.ba2 was a new texture: DiamondCity_Wall_01_d.DDS. When I opened it in Photoshop, it wasn’t a wall. It was a grainy, low-res photograph of a game developer’s desk from 2015—coffee cup, Post-it note, and a single line of handwritten code on a torn sticky: if (temp >= 110163) spawn();
The thermal anomaly spread. Users with liquid-cooled rigs reported their coolant hitting 110.163°F exactly, then plummeting. Not a Celsius conversion. Not a rounding error. Exactly 110.163.
I injected the patch into a sandboxed instance. My character—Nora, level 67, Minutemen general—was standing in the ruins of University Point. The moment the game loaded, the ambient track cut out. Then the “hotfix” activated.
All the raiders in the town square stopped moving. Their heads turned in unison, joints snapping 45 degrees beyond human limits. Their eyes were missing—replaced by two glowing orange digits: 110163. They began to pump. Not walk. Their arms moved like the slide of a pipe rifle—back, forward, back, forward—each pump accompanied by a wet, mechanical click.
Nora’s own hands spasmed. The screen text flickered: [PATCH NOTE: Fixed issue where player could die of old age. New issue: player can die of heat. Internal temperature: 110163 K]
Kelvin. It wasn't a typo.
My GPU fans screamed. The room’s ambient temperature spiked. On my second monitor, a terminal window opened by itself and began running a hex dump. The last line read: 0x110163 – HOTFIX – Asset: /VAULT111/CRYO/AWAKE/PLAYER. – STATUS: THAWING.
The patch wasn’t a bug fix. It was a message from a universe where the Great War happened in 2077, but the code was written in 110163 AD. A future so hot that processors think in plasma. The “pipe rifle pump” was their fundamental unit of time—the tick of a clock forged in a star’s core.
I force-killed the process. Too late. My character save was corrupted. When I tried to load it, Nora stood in a black void. Her Pip-Boy read: RADIATION: 0 RADS. TEMPERATURE: 110163 HOT.
She wasn't burning. She was becoming a fixed point. A patch note that forgot to be a patch.
The next morning, Bethesda released Patch 1.10.164. Patch notes: “Fixed an issue where the game would confuse temperature with patch version numbers.” But the Weapon_Rail_Pump_110163.hkx is still in the master files. You can find it if you know where to look.
Don’t install it. Don’t pump it. And if your CPU hits 110.163 degrees, even for a second—unplug your PC, go outside, and pray the shadow in Sanctuary isn't pumping back.
The primary reason players seek out this specific version is Script Extender (F4SE) compatibility. Many legendary mods were built for 1.10.163 and have not been updated for the Next-Gen versions.
Stability: This version is considered the most stable "final" release before Bethesda's major engine changes in 2024, which introduced new bugs like stuttering and broken quest markers.
GOG Version: The version of Fallout 4 available on GOG.com is permanently locked at 1.10.163, making it the easiest way to access this build without manual downgrading.
Mod Diversity: Most large mod collections and "wabbajack" lists still target 1.10.163 to ensure compatibility with thousands of legacy plugins. Key Fixes and Features of 1.10.163
While it lacks the native 4K/60FPS modes found in the Next-Gen update, version 1.10.163 includes all original DLC and several years of refinement. To understand the chaos, you must understand F4SE

stability. Here is a short story capturing the frantic "hot" moment when this update arrived and later became a sanctuary for players. The Last Stand of the Modded Commonwealth
The air in the Diamond City marketplace didn't just smell like synth-oil and noodle cups anymore; it smelled like impending doom. On December 4, 2019, word traveled fast through the digital Commonwealth: Update 1.10.163 had dropped.
For the average Scavver, it was just another day. But for the "Architects"—the modders who had spent years carefully layering 4K textures, custom weapon scripts, and complex settlement systems—this was a "hot" emergency. The update brought the Virtual Workshops
, a high-tech marvel that allowed players to build in digital realms like Grid World and the Desert Island. But it also brought the one thing every modder feared: a broken Script Extender (F4SE).
As the update hit Steam, the community scrambled. "Don't launch the game!" the warnings blared across every terminal in the wasteland. For a few frantic days, the Commonwealth was frozen in time. Authors worked through the night, coding by the glow of Rad-Stag stew and flickering monitors to bridge the gap between the old world and the new version.
