making settings save upon Game re-start

[DJ1]

Ok, new to this, so i`ve looked at in game settings
eg:
cg_fov 90
com_maxFps 60
seta r_vsync 0
etc.... I can use SHIFT+tilda to see full log, and whats been changed, but if i close, then re-launch IW5 the only setting that holds is FOV

are these things that need to be changed in the plutionium.cfg ??
or how do I make all these changes hold?

cheers.
