Hello

I Currently play battlefront 2 on steam deck and everything is worki'g well but i had a lot of crashes and After doing the following fixes everything work perfectly!

On the desktop mode you need to install the following tools "CryoUtilities" use the default settings of the program and everything work perfectly !

I follow the post of user "FER" posted 1 Month ago on proton DB

Also you need to check that the game is using Direct X11 and not 12

I personnaly use : GE-Proton 9-1

Hope this can help other people !
