the new version is supposed to automatically adjust to widescreen if you use a widescreen resolution
so short version is it depends on what resolution you use
I found that using 1680/1050 and 1400/875 it does indeed automatically set to widescreen view
however using 1280/800 which is the same aspect ratio it does not set to widescreen it shows as a normal 4:3 ratio for me
in this case I switched to 1024/768 to save frame rates and increased my field of view to 100 which gives me a widescreen view at a 4:3 aspect without any graphic deformations
my VC doesnt support higher than 1680/1050 so any widescreen resolution beyond that I cannot comment on
