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?
Problem: 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:
(1) rename the files in the tga folder and leave them there
(2) 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.
Answer: 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.
