Just been toying around, testing a few things out with my current RFB 1.26 install, and I started wondering if the ships really looked right in the scopes - just something gnawing at me about the sizes not looking quite "right" (compared to my memories of how they looked in SH3 anyway), so I decided to do some tests>
I set up a couple of simple missions in SH4 and SH3, each using a British Liberty cargo positioned as close to 1,000 yards away from my sub as I could get it (this was my first try playing with the mission editor in either sim - lost my first German sub to gunfire from the Liberty ship, after which I figured out how to start my u-boat at periscope depth

). Anyway, as you can see from the series of screenshots below, something odd does seem to be going on with the ship images in SH4 (w/RFB 1.26) compared to SH3:
SH4 Attack Scope at 6X:
SH3 Attack Scope at 6X:
SH4 Attack Scope at 1.5X:
SH3 Attack Scope at 1.5X:
As you can see, at 6X magnification the ship almost exactly fills up the scope view screen in SH4, but way more than fills up the view screen in SH3 (so, the ship "looks" larger at 6X in SH3 than in SH4). BUT, at 1.5X, the situation is reversed - in SH3, the ship spans about 40 degrees (based on the bearing scale at top), but in SH4 the ship spans about 60 degrees (so, the ship "looks" larger at 1.5X in SH4 than in SH3).
Is there any reason for this to be occurring, or is this an indication that something is "wrong" with the scope view implementation in SH4 (or SH3 maybe)? NOTE - as it turns out, I'm running RFB 1.26 with the "Betterscopes 1.2 Worn" mod on top of it, (and GWX Expansion on my SH3 install) so maybe it's something related to that particular setup - if I get time tomorrow I may try this with the stock versions and see what happens. Just wondering if anybody else has seen any anomalies like this with their setup.
