Hi, thanks for investing so much time testing mods.
it would be fine if you could post your system spec`s also...
...i see you have SDBSM`s additional crew sounds beta in use, did you saw any short crew animation interrupts and or warpings together with crew chat sound sample interrupt then (just some random interrupt`s of the current playing crew animation and chat sound sample until the next chat is triggered then)
...do you use a mod for a more real surfaced boat hight (lower profile), pitch and role behavior ? (i have a fine tuned personal special version customized by Stoianm here, it maybe need to be merged with TDW`s revisions for KZS Hull wetness for U-Boats + co tower and deck.)
...there should be an option for "Naights Submaine Textures (internal)", this interrior mod is next to Steel Vikings the most used one.
...plz note that "06 - Dynamic Environment SH5 Sounds V2.1" use only 2 channel inviroment sounds, they overwrite some SDBSM`s quatrophonic enviroment sounds. It`s of course only noticeable if you use more than 3 speakers. (i wanted to help Stoianm making his new enviroment sounds also quatrophonic but didnt have the time atm.

)
...also "05 - Stormys DBSM SH5 v1.3 optional NavMap babelling" is not loved by all, should be optional.
