Hello,

Is there a list of settings that can be changed "on the fly" without restarting the engine?

The only way to find them so far is by trial and error.. and that takes a lot of time..

Iirc, all of the settings are applied without having to restart the game.

That is true, you do not need to restart for the graphics settings; but by 'on the fly' it sounds to me like he means without the engine having to reinitialize the video. IE, you change the resolution vs changing tessellation.

All of the settings can be changed dynamically, however some of them require reinitialization of many elements (for example changing bump mapping requires resetting shaders for each mesh and that should not be performed in each frame)

I guess it will take time

That will be added with this roadmap element:
"•add more detailed comments/descriptions for functions in C++ headers"
