I have a GTX 780 Video card (drivers are up to date) and was re-configuring my monitor resolutions etc, and when I subsequently started Steam and Arma 3 all is well until I try using the Eden Editor and resume editing my latest mission build. I can load and edit older mission files but not the latest 2 versions of my build. I can play the missions fine but cannot edit these latest two that I saved. I can play them but not edit them in EDEN. If I try to edit these "builds", the editor crashes immediately following the display of the opening map overview image. In that image, before EDEN fails, I can see that my mission is intact. But for some reason, Eden crashes at that point. I went back and reversed all the changes to my monitor's / NVIDIA settings but no help. Note that all I changes was "resolution" combinations, i.e., changing 1280x10xx to 19xx X xxxx, etc. I DID NOT change the in-game performance settings that I have used for months and months with this card and which have been working fine. I was just trying to see if my monitor could display clearer text characters in a different resolution. But, unfortunately, EDEN now crashes on my "builds" when I try loading them for editing. I do save these files often and use a progressive file naming scheme so that I can go to previous files. This crash happens on the last two versions of this file but not on versions previous to that. Still, I would like these last two versions to work in EDEN because they represent well over 15 hours of my editing time. Thank you for the help. I really need you to figure this out since it's well over my capability to even know where to start. Ciao. BTW: I always generate a "Feedback Report" files so I have the latest uploaded to you. {F2488706}
