When running a game on a CPU-bottlenecked PC, which graphics settings should be decreased to improve performance?
In other words, which settings usually have impact on CPU usage (rather than GPU)?

Game settings which impact the CPU usage depends on the game itself mainly and also some what depends on the hardware combination used.
Generally speaking, the graphics settings that are usually available in the games these days that impacts the CPU are -
There may be some other settings also and it varies from game to game which may impact the CPU performance. These are just the common ones but may not be present in some games. Like the Draw Distance in Assassin's Creed Unity cannot be adjusted by the player as far as I can recall, it was fixed.
Then there are some advanced graphics settings which are optimized for a particular GPU manufacturer. For example the vastly popular Physx by Nvidia works very well on their GPUs and CPU performance is not much effected by it. But this option is usually disabled in case of AMD GPUs but if enabled (I read in some forums) it is mostly taken care by the CPU and it degrades the overall performance badly.
A big one I've noticed in The Elder Scrolls Online is SHADOW FX. Really any lighting effects, but shadows are the worst. Too much movement, (Especially in a high volume zone/area) particularly the other players shadows and the lighting to cause them.
Things like Sunlight Ray's and Reflection are worse than Bloom, and are least in my case, all the lighting FX are hurting me far more than the Distance or the Texture quality.
It depends on what game and what platform, taking CS:GO (A Steam game) as example, , checking option Disable the Steam Overlay
can reduce CPU usage, launch CS:GO with -nojoy
command also reduce CPU and memory usage.
