We have introduced a code of conduct. This change only codifies our existing rules, for any newcomers to read. All users are expected to abide by them.
Some newer, modern systems may suffer performance issues if using Windows 7/Windows Vista, using multi-core CPUs, or recently released GPUs.
To try and fix this you can do the following:
When SimCity 4 crashes on a multi-core system, assign it to a single CPU according to this tutorial or by adding -CPUCount:1 in the launch options through Steam or in the "target" field of a shortcut to SimCity4.exe (Retail or Origin version).
There is a bug within the game where almost every IH lot in the game doesn't offer any high wealth jobs even though it creates a demand for high wealth residents. IH Missing Jobs Fix takes care of that and will have people filling up those IH jobs, allowing your lots to prosper and grow.
When you have two or more copies of the same city in your Region folder upon starting SimCity 4, the game uses only one version and the other city copies are either deleted or automatically moved to the Downloads folder. SimCity 4 determines which file to use by sorting the city file names alphabetically and taking the first entry.
Example: If you have the following city copies in your region folder, then only "City - TEST 1.sc4" will be kept, the others will either get deleted or will be moved to the Downloads folder:
City - TEST 1.sc4
City - TEST 2.sc4
City - TEST 3.sc4
City - TEST 4.sc4
An integer overflow bug is also present in the game. Under certain conditions, the Junior Sports Program and Parks and Recreation expense items will be a negative value - thus adding to the end of month balance instead of reducing it.
The game has major flaws when operating on computers by Apple using Intel processors. Aspyr released a beta of a patch to fix the problems in 2007, but the patch was never finalized and many bugs remain. Some have a serious impact on playability, including frequent crashes if a city exceeds 95,000 population, flawed display of the water surface, frequent blurring or replacement of objects with random other objects, and an inability to significantly accelerate the vehicle in driving mode that prevents many gameplay features from being unlocked.
Minor issues and fixes can be found here.
Custom resolutions are possible, with caveats, as explained at Widescreen Gaming Wiki.
The simplest way is to put -CustomResolution:enabled -rXResolutionxYResolutionx32 in the launch options through Steam or in the "target" field of a shortcut to SimCity4.exe (Retail or Origin version). Example for 1920x1080 at 32-bit: -CustomResolution:enabled -r1920x1080x32
To have SimCity 4 launch in windowed mode use the parameter -w in the launch options or the target field of the shortcut. To revert, removing -w is not always enough. If you get stuck in windowed mode, use the parameter -f to revert to full screen on launch.
To disable the intro, use the parameter -intro:off in the launch options or the target field of the shortcut.
More parameters can be found via this link. Please be aware that if you use the -UserDir parameter, changes made in any ingame options may not be saved properly.
There is no multimonitor support according to Widescreen Gaming Forum.
The game doesn't support any form of antialiasing.
There is no anisotropic filtering option available in the game.

Please keep in mind that some mods may require dependencies. Dependencies are files essential for properly running the mod and must be downloaded. The dependencies for each mod are listed on the respective mod's page. Also, the sites on which you will find these mods require that you create a free account in order to actually download the content.
Some of these mods, and many others, can be found on the site Simtropolis.
Many texture packs exist for Simcity 4. They are hard to find, so this is a WIP section.
