how to make SimCity™ 4 Deluxe Edition run stable on modern systems

1. force the game to run on only 1 CPU core. (early 2000's games were developed and optimized around single core CPU systems, not multi core ones)
insert this into the advanced launch options for the game, found in properties -> general, then under launch options -----> -CPUCount:1

2. run a 4GB patch exe, this is also essential for stability, especially for modded installs (i recommend only installing mods made for performance and stability. the more stuff you install for your game, the more likely you will encounter longer loading screens, a higher chance of your cities being corrupted, as well as a higher chance for game crashes and freezing.)

3. install NAM (Network Addon Mod) NAM fixes a plethora of simulation bugs, broken pathfinding, poor traffic routes, as well as performance issues. with this mod, traffic in your cities will take the most optimal and efficient transportation routes possible, making the most out of your cities layout. not only that, you can select what kind of capacity roads/avenues/railways/subways have. setting traffic capacity to the highest setting in the mod's installer makes the game a breeze to play, making traffic constraints a thing of the past.

4. play in windowed mode. running simcity 4 in windowed mode allows for fewer frame pacing stutters, smoother camera scrolling, more stable alt-tabbing, as well as smoother frame rate. often times in late 90s/early 2000's games, playing a game in fullscreen on a modern system is prone to issues concerning high refresh rate monitors, variable refresh rate, multi-monitor setups, etc.
insert this into the advanced launch options for the game, found in properties -> general, then under launch options -----> -w -CPUCount:1

5. do NOT use software rendering. just don't do it. it tanks performance severely and there is no upsides whatsoever to using it at all.

6. (optional, up to your own discretion) play simcity 4 on linux. linux with the wine/proton compatibility layer ironically enough, runs legacy software better than modern windows itself. microslop doesn't really give much attention to how well older legacy software runs on their OS, meanwhile developers for wine and steam's proton compatibility layer (proton is just a customized version of wine optimized for gaming btw, primarily developed by Valve in collaboration with the linux community) are constantly working and putting out updates so that legacy software runs as smoothly as it possibly can. don't expect games with built in anti-cheat software to work though on linux, that's still a work in progress. some games work, while others don't.

linux distros i personally recommend are bazzite and fedora silverblue.

here are several stability/performance mods that will also help with playing simcity 4 that you can look up online -
4GB Patch - allows simcity 4 to have access to 4GB of ram instead of 2GB
SC4Fix - fixes critical bugs that causes crashes/freezing
SC4 CPU Options - fixes more critical bugs related to CPU handling
SC4 Graphics Options - fixes critical bugs related to GPU handling, and introduces quality of life enhancements
Startup Performance Optimization DLL - optimizes and speeds up loading times
SimCity 4 Disable FPS Limits - removes fps limiter and increases performance

HOW IN THE H E DOUBLE HOCKEY STICKS IS ALPHA PRIME THIS GOOD???

this is not even some hidden 10/10 masterpiece that everybody unfairly ignored. this is a completely normal, borderline mediocre 6/10 sci-fi fps from 2007. the enemy ai sometimes runs directly into gunfire like it has somewhere important to be, the voice acting sounds like everybody recorded their lines at 3:00 in the morning, and the story is delivered with the confidence of a man explaining a dream he only half remembers.

this is literally the exact kind of game you would find for $4.99 in the pc game section at ollie’s bargain outlet, buried between 30 obscure casual hidden-object games and something called “terrorist takedown 3.” which was released in 2004, yet based off the in game screenshots on the back of the box, looks like a cheap copy of delta force 2, a game from 1999. (delta force 2 from 1999 is better than the free to play delta force 2025 remake, crusty old janky games that you would install on a beige Windows 98/ME/2000/XP computer just hit different)

this budget eurojank doom III ollies bargain outlet “oh im surrounded by a dozen casual hidden object games and fps’s with graphics that look 5+ years older than from the release date” looking ahh game slaps so insanely hard my dumb gen z zoomer brain is unable to comprehend. WHY IS THE MAIN MENU MUSIC SO DRAMATIC AND EPIC WHY WHY IS IT SO GOOD??

here are some rough examples of one particular characters dialogue

“Aaaaah! Another nutcase! Mutant! È un po' toccato! Hubbardium! Heeelp!… Em... you are... normále?”

“Arnold! Paolo knows this thing! Very dangerous! Beautiful woman! Strange Hubbardium! At night Paolo hears it inside the walls, singing like opera, but bad opera, porco zio! Do you believe ancient space legend? Glomar, Arnold! Very old space legend! Paolo does not believe such nonsense! But perhaps Paolo believes little bit! This Hubbardium makes men crazy! Also machines! Maybe doors! Paolo does not trust door! Your brain is up the spout, Arnold!

“Arnold, you must listen to Paolo! Beautiful woman knows something! Beautiful women always know something, but never tell Paolo! Very suspicious! Paolo injured! Look at leg! Terrible injury! Maybe permanent! Definitely permanent for Corporation paperwork! Pension, Arnold! Paolo deserves excellent pension! Small house! Perhaps garden! No more asteroid!”

“Wait! Noise! Soldiers coming! Paolo cannot fight because injured pension leg! You fight! Paolo gives important advice from behind strong box! Go left, Arnold! Or right! Paolo does not remember! This place all looks same!”

“Strange Hubbardium is speaking inside Paolo’s head! It says terrible things! Maybe ancient space people still here! Glomar! You laugh before, Arnold! Now who laughs? Not Paolo! Paolo is injured!”

“Hurry! Beautiful woman waits! Paolo trusts her completely! Except perhaps not completely! Maybe fifty percent! Good enough for beautiful woman!”

“Arnold! You go first! Paolo follows safely behind! Paolo always with you! Unless dangerous! Then Paolo waits here! But spiritually, Paolo always with you!”

“AUGH! Owww! They have killed Paolo! Paolo is hit! Poor leg, completely dead! Blood poisoning is already coming! No, Paolo go nowhere! Paolo is cripple! Disability pension! Io me ne frego! You can go alone, Arnold! Save Warren, find Glomar, shoot the crazy men!”

arnold: hmmmmmmmm okay paolo the cripple.
