How to find out how much CPU is eaten by any mod ??

[Gordon Dry]

So Process Explorer doesn't help me, I want to actually see how much resources are used by a single mod .dll - but how?

When I check cities.exe with PE and then check the properties, I don't see references to the mod .dll's but to core .dll's and mono .dll's ... that's all.

How to see the CPU usage, the RAM usage and the I/O usage of a mod .dll ?

I don’t think you can, at least for most cases and not in an easy way if possible at all. A mod is a modification of the original, and that includes tweaks (No Clouds mod gives you more fps, for ex), replacing chunks of the original code (AI mods). If a mod adds a new thread could be easier to monitor directly the resources used, but don’t think it is usual (if any).


My bet the only realistic way is having a savegame for benchmarking. And with some mods with ingame options you can see the difference in performance in real time, like many graphic ones.

Exactly. The dlls attach to and in some cases even overwrite original codes. The effect on CPU and RAM hardly depend on what the mod does. The No Clouds mod @Doctor Machete mentioned is a good example as it might eat a few kb more RAM while reducing CPU and GPU load. Mods which however run for example a lot of code in ThreadingExtensionBase are more likely to have a negative effect on CPU/GPU.
You might however be able to use a Mono profiler to get some data, but that's more for experienced developers and it's no easy task (if possible at all).
