Now that DynamicSurroundings is gone (love it, but way too many issues), Ambient Sounds is a really nice and simple alternative for adding world ambience. Should have little to no performance overhead from my testing.

I have tested this mod and it actually has a significant impact on performance, especially in the presence of Sound Physics

Thanks for the suggestion, I will take a look on this mod later!
Want to warn, that DynamicSurroundings is not part of E2EE and only listed in "recommended" mods list.

Thank you for the test! Now I will know that we don't want to add it =)

Having played with AmbientSounds more, I have been noticing significantly more stutters. Removed for now, wouldn't totally recommend unless for those who absolutely need the effect
