Hitman, your point is well taken.
I had not thought of looking at the bridge view and have it relate to the new scope views until you brought it up. The only views that give you the tools for making assessments for measurements were the scope views, so I have concentrated my efforts on them. I'll be able to make the adjustment to the bridge view, making it a bit smaller than the scopes. It's just that I'll have to "eye ball" the relationship (yep, pun intended).
Here's the difference between the two views as they stand now. As Hitman pointed out the difference between the two is too great to be considered accurately portrayed.
The above (and below) pictured test mission is having the Akita at a 1000 yard distance (1001 to be exact).
If you wish to check target ships with the same type of mission test I'm using you can download it
HERE. It's simply called "Test 21" and will be found in the "Quick Mission" menu of the main game screen. It has several target ships positioned around a stationary sub. The down loadable "Optical Test Mission Pack" (JSGME compatible) has two mods. The above mentioned test mission and Captain Cox's "Big Bearing" compass for the attack periscope. The compass should help as you check the field of view degree findings. Extract each mod
separately to the JSGME "MODS" folder to activate.
Using both mods, you can check the stock field of view yourself, and come up with your own conclusions. Try the 1280x1024 resolution for a different size than the rest!! Depending on the monitor you use, some of the various resolutions will of course appear distorted. But, as you compare the relative compass bearing to the outer views edge you will see a consistent degree figure used (except for the1280x1024), no matter if the view is distorted or not.
