How does one maintain the aspect ratio in fullscreen? Also, is it possible to have it windowed with 2x resolution? How does one do this? I've noticed a lot of slow down when doing everything in the conventional way on my pc as well as others. Is there a good way to avoid that?
Boy, this sounds familiar. There's a maintain aspect ratio in the application settings, and you can also have the application window be larger with the option to resize the display to fill the frame checked. Just investigate the application properties box!
Also, you can use the window control object to change window sizes during runtime. (So you can switch between modes.)
