[HELP]Passing from Debug to Release

Hye, I'm working on a project and I am trying to pass it into release, because in debug version of Ogre and others, the FPS is to low.

On visual 2005
downloaded Ogre 1.2.0 dagon(release version), OgreNewt 1.62(latest version), and Newton 1.52(latest version)

I compiled them in release version, and passed the librairies in my project.

I tried to compile my project in release settings, but had this errors on the link:

And I hope you guys couldhelp me debug this...I really can't manage to do it on my own, and it's a critical moment of the project.

(for more clarity, I've put a - in front of each line and the first word in bold)

if you are using MSVC, make sure you go into the project settings (with "release" configuration selected), and set C++ -> code generation to "Multithread DLL".

For the Runtime Librairy : Oops
Shame on me

But still not working for the sound problem, even after checking if the Linker input is correct

I'm working on it, through help from the Ogre3D.org forum section.
I will let you know how it is going, in case others are using FMod and having same kind of problem
