Thanks again for your answers obesebear and DLBP
I'll try to redo the installation, and tell you if I managed to install it clearly
By the way I'm very impressed that you answer really quickly

-EDIT-
After some researches on my files and all, I found that I hadn't the Aali 0.8 driver or highter version, but the 0.7.
So
*Requires Aali's driver version .8 or higher* Open ff7_opengl.cfg and add line battleswirl_framerate = 60. Then set Vsync to no. Save.
Simply couldn't work (I suppose that's the reason...).
What I've done to have my ff7 version (I may have done bad but it worked well).
I have the re-release 2012 version (downloaded from the SQ-E Store), and I converted it to a FF7 1998 version thanks to a software. And then I modded it with Bootleg (Tifa's package), vanilla version, overhaul etc... With that, I patched it in order to play the New Threat Mod (Which I love it <3). It works but it's kinda slow as a I said before (I saw that it's actually normal, battles are at 15 fps, but it ran at 9-10 fps...) That's why I wanted to boost up in 60 fps.
I know that I should not use bootleg if I want the NT mod, but if I don't use Bootleg, I can't make FF7 work, weird huh...
Maybe those will help you to find what's wrong, thanks a lot <3 <3

-EDIT 2-
After several tries, I actually managed to make the battles faster... But several animations were weird to see (Barret's Attack animation), and some were simply not animated (Cloud's Braver)... So I just give up this time, I actually managed to get the 14-15 fps like before so I'm OK with.
Thanks a lot <3
