Hello Timon,
Quote: "I have a high rig so I really prefer the maximum quality, please can you tell me what I have to change in setup.ini to have the best quality like you said (lighting, textures....ect). Thanks"
What to do to get better lighting it's hard to say because the lighting of a scene is a function of many variables as shown below, so you should use a lot of trial-and-error technique.
f(G,L1,L2,T,S,Li,Lc,Lp,R,Ln)= best lighting quality
G= gpu (Graphic Process Unit) features as well as its memory size;
L1 =lightmaptexsize;
L2 = lightmapquality;
T= texture quality (diffuse, normal, specular). For poor textures maybe
darker areas be a better choice;
S= quality of the shaders applied on objects on the scene;
Li= light intensity;
Lc= light color;
Lp= light position;
R = quality of the game engine rendering system;
Ln= number of lights on the scene
In this case, you should change some variables in setup.ini file such as the lightmaptexsize and lightmapquality or changing the values of the light intensity, number of lights on a scene or the colors of them. Sometimes it is necessary try to use various types of shader effect on an object and see which of them produces better results because often the object may become very clear as if it were a plastic or a wet surface or too dark losing the scene lighting its realism.
It may happen that do not use any shader effects at all make the scene more realistic and natural.
Remember that the use of shaders in general requires more processing resources of the computer some kind of shaders more and some less.
Regarding to FPSC I have found good lighting results with the following values:
lightmaptexsize=256 and lightmapquality = 100 - produces fair results on computers with poor graphics boards or for those with decent 3D video boards, without much harm the performace during the game.
lightmaptexsize=512 and lightmapquality =100 - produces good results on computers with budget graphics cards; however, it will require more resources and processing.
lightmaptexsize=768 and lightmapquality = 100 to 400 - produces very good results in both computers with poor graphics cards or with great 3D video board requiring more memory and processing resources as well.
Wolf wrote an excellent tutorial titled Lightmapping which you can find the link below:

Edit Start:
Furthermore, in the following link are some screenshots showing the same scene with different settings of illumination changing only two variables: lightmaptexsize and lightmapquality.

All textures of the walls and floor with diffuse, normal and specular mapping and effect bump.fx as well.
It was used the effect phong_bump_specular.fx to the textures of the barrels and storage entities.
Walls lighting fixtures with effect illuminationent.fx activated
Edit End.
I hope all these informations may be useful for you.
That's it!
Good luck!
