How do u adjust to keep aspect ratio the same?
I moved as close as I could to a game save box. You can find them in gun shops and headquarters and ...
There is a circle printed on the box around the picture of a floppy.
Without the tool running, the circle diameter measured on my screen as 22cm horizontal and 22.1cm vertical or something like that. So, it is not a perfect circle. This is on a 21" at 1680 x 1050.
I adjust X and Y using the tool until I see the amount I like to see. Then, I adjust only one (X or Y) until the circle measures about the same horizontally and vertically. Then, I know that I have not changed the aspect ratio.
So, if I were you,
1- I would run the game without the tool and measure an object Y and X using a ruler. Pick an object that is a circle or a square to simplify and a large object to improve your measurement accuracy. Let's say you measure X=20cm and Y=20cm.
2- Then, quit and run the tool and start the game again. Use the tool to reduce what you can see vertically until you do not see the shoulder that bothers you.
3- Then, measure the same object you measured in 1 again. Let's say you now measure Y = 18cm. So, you must adjust X until you also measure 18cm horizontally. That means you have not distorted the aspect ratio.
Edit:
You adjust X by pressing numpad + and -, while tool is active.
You adjust Y by pressing Shift numpad + and -.
