You didn't answer the question.
You didn't ask
, I could not guess that this was the detail you asked for.
What focal length do you set?
Usually I don't set it, it is detected correctly (with +- 2° fov difference max between the pics, but an RMS of 2.5). However I tried setting all source pictures to the correct expected focal length or FOV 30/35/40, although 35 is the calculated real FOV for this case.
So the resolution and aspect ratio of your source images may vary?
All perfectly identical, same resolution (usually 4224x2640 for directx 9 based, or 6384x3584 for directx 10+ games).
This set is a bit different since I have to cut of the left third where Lara is in view. If you know a trick how to hide her from screen just say *g*.
Do you use the multiple viewpoints option?
No, never. However in THIS case it IS worth a try when it happens the next time, since that game does not allow me to turn the camera completely without parallax effect. It is always placed "behind the head", even when weapon-zoom-aim is used.
EDIT: Using "Multiple viewpoints" makes the detection even worse. A lot worse.
Compared to PanoramaStudio: They do have an option to set the approximate focal length for detection.
Use autopano giga to create panoramas from computer games? Yes! http://joumxyzptlk.de
