Anyway, I forgot to post the guide I use for change the boot options:

Here they tell how to restore the boot options in case any program or game have troubles with the new changes.

The game today still going perfectly. And fractals too. 0 crashes in fractals is a tremendous achievement for me, because is where most of my problems come.

So, this works. Hope this helps other people.
