grazie!
I've installed that mod and now underwater watching is good, but now time compression limit is set to 512 even when there's ship in view.
With twos i remember that limit was set to 64
I don't play full realism, i kept all the fuel, oxygen, repair time, reload, dud torpedoes etc. on... but (ok you can spit on my face) i don't use the real navigation mod, so sometimes may happen that on tc higher than 64 i find some ship...
I hope not to break something
