Modder ‘lStewieAl’ has released a must-have mod for Fallout New Vegas that improves performance and significantly reduces load/save times.
According to the modder, this mod rewrites over 1,000 functions in the game, improving algorithms and using the latest compilers. As such, the mod can improve in-game performance and significantly reduce load/save times.
Going into slightly more details, the modder used a profiler (Intel VTune) to find performance bottlenecks in the game’s code. lStewieAl then rewrote these bottlenecks and compiled them with various optimizations.
The modder claims that the game’s code has memory constraints due to PS3 and X360. Since the game also came out on consoles, the developers opted for slower but smaller code. As such, the mod rewrites the game code to favor faster code or better algorithms.
Ultimately, owners of weaker PC systems will be able to run this Fallout game with higher framerates. I know, I know, New Vegas is a really old game. By today’s standards, most PC gamers can brute force their way. However, we’re talking about a free performance boost. For instance, some PC gamers reported higher framerates in crowded places. And since the game uses legacy code, it will have long loading times no matter what PC system you use.
So, even if you own a high-end PC system, we highly recommend downloading this mod from here. As said, it can significantly reduce the loading/saving times which is something that a lot of New Vegas players will appreciate.
Speaking of Fallout: New Vegas, we also suggest taking a look at these mods for it. Last month, we shared a mod that added a real-time reflection system to the game. Fallout: Broken City, Fallout Van buren Remake, Fallout: Nuevo Mexico and Star Wars Open Worlds are four fan expansions that are currently in development. On the other hand, Fallout New California, Fallout: Free Cheyenne Demo, Fallout New Vegas: Out of Bounds and Fallout The Frontier are DLC-sized mods that you can download right now.
Have fun!

Impressive!
“. I know, I know, New Vegas is a really old game”
No one plays new vegas undmoded the more mods you have and the more time you play the performance drops severely
Remember that this mod is best used in a new game as well as the new vegas reloaded graphics mod
This sounds like a lot of grind work. It is hard to research and rewrite even 5 functions but they did 1000 just for this game.
If only that were true. The mod does far less than claimed and based on what ida shows, most of it is ripped from starfield and the improvements Bethesda made and since it’s the same engine they just work plug and play
Don’t want to discount someone making improvements but… Be honest about what they are and what they do. Almost all of these things are already done by many individual mods available for the game
How is that even possible when this mod was released before Starfield was out?
Dude you dum’ af.
Will this work for Epic game version???
Should work
Console focused game developement still hurts pcgaming
Always did and always will
I agree but modern controllers are an amazing thing for pc games so there are some benefits as well.
yes but no. this game run orribly even on ps3 and xbox 360 for their standards.
I installed FNV on an Intel Atom 5Watt(!) MiniPC (4×1.4GHz, Cherry Trail ‘graphics’). It is playable, but will benefit of this work the most?! Amazing work!
