Thanks again for answering so fast.
Well i found a preset for DoW II, used it and retribution and it does not work, so i tried on DoW II (base game) and it didnt work neither. I assumed it wasnt the game, but i should be wrong then.
Yes the preset i found preconised 1.5 so thats the one i used. Link to the preset :

I dont think i can make my own preset tho, because even with all post-processes turned off it crash anyway.
Any lead ?
Sorry for my sometimes misunderstandable english.
EDIT: The way i install preset isnt the problem (i think, given the fact i use it on most of my games already, this is the 1rst time i have this problem, but i can be wrong.)
