For the record, if you're using Bottles (or just installing manually), Plutonium just needs dotnet48
dependency/winetricks verb and the latest visual C redist (those released after 2015 bundle in all visual C libraries from 2015-onwards)... and DXVK, but it's probably safe to assume at this point.
Aside from that, the games need the xact
dependency/verb installed in the prefix for sounds to work (and for T5/Black Ops 1 Campaign/ZM to work at all).
I've noticed that sometimes it'll crash at launch--I thought this was something to do with online mode, but no, it's just a random failure to launch sometimes. I also could've sworn that Nvidia cards required NVAPI to be enabled in the prefix/game profile to work (at least for Black Ops 2), but that doesn't seem to be the case anymore.
