Wide screen for menus or widescreen for gameplay? If you want gameplay widescreen with proper aspect ratio you are gonna need San's IL-2 FOV changer otherwise your game will be a stretched 4:3 aspect ratio instead of the typical 16:10 for widescreen LCDs. If you talking about widescreen menus, apart from using the Ecran Wide mod I don't know what to tell you. If it's not working anymore then they possibly need to update it for UP 3.0 but I would have thought that would have already been a taken care of if not integrated into UP as its a no brainer.
Well I think widescreen for both, there is a widescreen mod included with the UP 3.0 install and it just isn't working....nor is ecran for 4.101
haven't had time to install myself, but read over at the UP site something earlier, that widescreen has to be activated after UP3, not before, just in case you have.
