Every ship is the same. Or at least every ship that I've played, anyway. Since 7.4 came out I've only played Kamikaze R, Khabarovsk, Kagero, Richelieu, and now Asashio.
From #00 through #04, I had the torpedobeats and mermaid's wrath sound packs installed, but with #04b I took them out. I was actually using the stock sound instead of MW, and I wasn't hearing the torpedobeats song at all, so I left them off.
I'm really hoping that I don't have to reinstall the whole game from scratch... that would get very annoying, very fast. Expensive, too, on metered internet.
Any chance that EVGA Precision XOC might be interfering, due to the OSD? Or some new thing from nVidia?
edit to add: I've done the check-and-repair through WG's launcher, and in safe mode things seem to work fine as well.
