@swesonga filed a bug for this, not sure if this is what you're referring to? https://developercommunity.visualstudio.com/t/fmod-incorrectly-returns-NaN-on-certain-/10793176

I think this might be an issue with Visual Studio rather than Windows itself. Admittedly I really don't like all the conditionals either, and am hoping for it to be fixed in VS soon so I can delete the workaround entirely, but there hasn't been any news on whether this has been fixed yet or not.
