@AxlRose01 Sounds good but its not working. A google search said me that driconf does not work with propitary nvidia drivers that i use. Anyway, thx for the tip. @DanKegel Yes, i confirm to this. I'm in email contact with the main dev of the game so maybe i can ask him to provide a test account for a wine dev. How can i contact a wine dev before? I don't want to bother the game developers before being sure that a winedev will look into this problem when i get an account. Thx for you comments guys, i'm still not giving up to fix this. ;)
