Hi! I am doing some modifications to the System.cfg, but the strange thing is that there is not changes in the CryEngine. I would like to modify some files and options. It's as if there was to be used by the software.
What can this be?

It's recommended to leave that file alone, if you'd like some commands to load on editor load create a user.cfg instead.
If you want some commands to load on game load, create a autoexec.cfg.

Which version of SDK are you using ?
It's working in 3.4 and I can confirm that it didn't worked in any previous release.

..Idon't know much avout the autoexec.cfg. this file is exactly the sam as system.cfg? or has something diferent?

Which version of SDK are you using ?

I'm using the 3.3.5 version, works well
maybe I should donwload a new version

autoexec.cfg is loaded durning level load, while system.cfg is loaded on application start (either editor or game).

Yes I made ​​some modifications to the file is new version of CryEngine set some important details from what I saw. I need to do now is learn how to edit more files, such as the .cfg for the system.

Thanks!
