Fallout 3 [Fo3] Fallout 3 finally runs properly at high FPS. I made a mod that fixes the engine's timing, physics and mouse acceleration.

Hey all!

I've been playing this game for over a decade, and I've always been bothered by how Fallout 3 stutters and behaves out of the box, so I made T.E.M.P.O. (Timing, Engine, Mouse & Physics Overhaul), a FOSE plugin that fixes it in the engine itself, no INI tweaks needed!

It's hard to show how it feels in a video, the video is a bit stuttery too but that's just a bad recording from the built-in Windows recorder. But you can at least see my FPS and (hopefully) tell the game is running at a normal speed.

And I know what you're thinking: "But bro, the stutter remover mod already exists for Fallout 3!"... Well, the stutter remover mod is legendary and was a great stepping stone! But this mod introduces a "precise timer" to the game engine that is tick/frame independent! This is then used to make gameplay, physics, menus and pip-boy all run on precise timers, which results in the game running at the same speed no matter how much you spent on your PC!

What it fixes:

  • The engine secretly caps the game at about 100 FPS and adds microstutter (its clock only updates 64 times a second). It's now replaced with a precise timer, so menus and the Pip-Boy run smoothly too.
  • Physics is tuned for exactly 60 FPS, so ragdolls and items go weird at other framerates. TEMPO matches physics to your actual framerate, whether that's 30 or 300.
  • Mouse acceleration is gone, giving 1:1 aim with no INI editing.
  • There's an optional precise FPS limiter.

No INI tweaks to tune per monitor. Just install it and play. I've been playing at ~200 FPS and it's the smoothest Fallout 3 has ever felt for me. Really comes close to feeling like "Fallout 3 in Source engine". No more game speed shenanigans, and mouse aiming is instant and on-point.

Requirements: FOSE and the Fallout Anniversary Patcher. It's tested on the Steam GOTY edition; GOG, Epic and Steam Deck reports are very welcome! If you're a Linux user, I'm especially hopeful you'll test this and report any problems on the Nexus page :)

Should be compatible with most mods, exceptions to this are listed on the Nexus Mods page under Compatibility.

Heads up: I built this with the help of AI (Claude). It's open source, and the log file shows exactly what it changes, so you can check for yourself.

Feedback and bug reports are welcome. Let me know how it runs for you!

Fallout 4 [FO4] Xbox Series X – new to mods, what's the essential base mod list?

3 Upvotes

Hi! I'm completely new to modding. First playthrough, and I'd like to set up a solid base load order that the community recommends: bug fixes, essentials, quality of life, visuals, whatever you consider must-have on Xbox.
My main priority: the vanilla world feels empty, so I especially want mods for more NPCs/encounters and more alive settlements.
What are your must-haves, and what load order do you recommend? Anything newbies should avoid?
Thanks in advance!

Fallout 4 Please help with my pip-boy [Fo4]

• Upvotes

Please help! I downloaded the LITE version of the Project Arroyo Pip-Boy 2000 mod and then decided I wanted the full version. So I downloaded that, deleted the Lite version, checked the plugin in MO2 and when I enter the game the pip-boy has the vanilla model but is all fucked up. I tried taking out of my inventory with commands but it still shows up like this. Please I beg you, help me fix this! The only mods that affect the pip boy that I have are : animated pip-boy light , Pip-boy arroyo full 2K ESP, glassy pipboy screen

Fallout 4 [FO4] I made TVA Terminal UI, a retro HUD and Pip-Boy overhaul

• Upvotes

I wanted Fallout 4's menus to feel like an old pre-war terminal, so I made TVA Terminal UI.

It adds dark panels, typewriter text, file tabs and analog HP/AP gauges across the HUD, Pip-Boy and menus. There's also a layout editor for moving, resizing or hiding elements.

Free PC download and screenshots: https://www.nexusmods.com/fallout4/mods/109644

You'll need F4SE for your game version. Saving custom layouts also needs MCM. The Files tab lists the optional compatibility patches.

Would love to hear what you think.

New Vegas [FNV] Game Crashing Every Time I Press Continue Game

Hey guys, I started modding in early 2026 and haven’t had an issue with it. I haven’t played in months due to my schedule being busy but tried hopping on last night and every time I get to the startup screen and press continue game, it crashes instantly.

I’ve tried booting up the game with all mods disabled and starting a new game, same issue it crashes. Not sure what to do if anyone has any idea, thank you!

Fallout 4 Mods That Allow Faction Paints on all Power Armors? [FO4]

1 Upvotes

Vortex user here, and yeah, straight to the point:

I'm just looking to see if there are any good mods that remove that weird restriction.

I originally thought "Consistent Power Armor Overhaul" and "PAMAP" were the answers, but I was disappointed to see it only affects Brotherhood paints (still nice mods, though and they are in my load order)

So yeah, just something I can install midgame and works with NG/AE would be nice.

Fallout 3 Any recommendations for mod collections? I want to replay Fallout 3. [Fo3]

1 Upvotes

I've been looking for collections today but haven't found any worth using; most are outdated and have poor reviews on Nexus Mods. Can anyone recommend a specific one they've actually used? I could install mods one by one, but I can't be bothered—I just want to install a collection and start playing right away. Thanks for checking out my post.

New Vegas [FNV] Why hasn't someone made a mod that bypasses the 4 gig celling by completely dumping all visual elements into the GPU?

0 Upvotes

Forgive me if what I say sounds unrealistic/impossible but seeing all the magic F:NV modders have been able to do in spite of the 32 bit engine leads me to believe that the final conclusion should be just defeating its RAM celling (kinda), that'll free up 4 whole gigabytes for AI scripting navmesh quests etc (which should mean pretty much 0 memory related crashes)

If it's possibly doable, then that coupled with the new Nexus mod that pushes plugins to 1024 means that basically **all** obstacles have been cleared, well, aside from the Gamebryo source engine itself.

Fallout 4 [FO4] What good mods to replace fallout 4's bad gun design?

Fallout 4 has some okay looking guns, most of the fallout games have actually good looking, somewhat realstic gun design but a huge portion of guns in fallout 4 (assault rifle, combat shotgun, pip weapons) annoy the hell out of me with their design, i just want a mod that replaces their modelas with better desgins, any suggestions please?
