Screen...more like projecting it on a wall. Or maybe a Cinema screen.
I had to increase MegaMek's memory just for the map to load. It started with 4GB. Nigh on 30 mins for turn ones moves to complete.
It always crashes at the start of turn two, with out of memory errors.
Its more likely the JDE having the problems, than MM itself. As I gave It 8GB after the first time.
After running the scenario twice. I'm not going to futz around with it any more. It was just to see what what would happen.
