I've been doing a few more experiments this morning with a couple of different aircraft the Bf109f2 and Fw190a3. The settings below work with both of these aircraft

Here are the settings to use when setting up the shader
Top left
x = 536
y = 86
Bottom right
x = 936
y = 312
I'm working on a one-size-fits-all compromise to get one set of settings that work with most if not all of the aircraft that I fly.
Note - These settings are based on my screen res of 2715x1527 you need to adjust according to your screen res.. So , for example, if you run at 1920x1080 then divide 1920/2715 = 0.7 (this is the magic number :))
Divide the top left X (536) by 0.7 =
765. This will be your top left X setting . Do the same with your bottom right x setting (936/0.7 =
1337)
Top left Y co-ordinate will then be 86/0.7 =
123 and bottom right Y co-ordinate will be 312/0.7 =
446.
For other screen resolution substitute your horizontal and vertical resolutions into the above formula. Once you have the magic number then you can use when calculating magnify shader coordinates whenever you need to,. I do a screengrab of the cockpits, overlay them in PSP and then use the crop tool to work out the size and position of the magnify area (make sure to keep your screen res set correctly when adjusting the crop tool , eg. 16:9, 4x3 etc.. I then make a note of the x and y coordinates top left and bottom right and fine tune if necessary but you can get a very accurate figures to start with so you shouldn't have to fine tune.

PS. You can setup the initial position of the magnify area anywhere you choose, I've chosen the area around the gunsight but you might want to do the dashboard area. You can still use the ingame zoom/pilot head forward/back and pan controls in magnify view.
