The advantage of this entry is, that you can choose a resolution that is bigger then your screen. I did the same screenshot at a width of 3000 (2250 height - 20MB)
The cut out is actually bigger then a regular screen (1125*1071) - it is in a spoiler due to the size. Notice the detail of the forest in the background?
Sometimes there are problems to actually get the tga files. You press the PrtScr button but there is no picture in the tga folder.
I found this only happens when you:
rename the files in the tga folder and leave them there
when you break the sequence of the files (when you have for example 5 pics in there and you delete one of the files)
Don't know if this happens to anyone but for me it helped to move all
of the take tgas to a new folder when no screen shots are taken. or you should just leave all of them in there - unchanged.
You are correct with the assumption about renaming and order of the screen shots. The names have to be in sequence. I usually move them somewhere for editing and delete the contents of the folder
Lines through screenshots
Work out your screen's native ratio, eg 1680:1050=1.6 and then add this line to the [video] section n your CFG file:
tga_aspect = 1.6
This will give you a full size battle screenshot without the line.
