The event cam is always the first to go in my games. However I always keep the free cam. Which is even worse realism-wise I guess

But with GWX, the hig res fix, MEP environment, sober's waves and Sh4 effects for sh3, the graphics get so good I sometimes just like to check out the environment or make some screenshots with the free cam.
I wish you good luck on your career and especially your resolution to sit the entire war out. So far on a dozen careers or so for some reason I always find an early grave halfway through '43...
Happy hunting!
