>>105897788gta san andreas on the ps2 used ogg vorbis for all its sounds, the game was a huge open world that really pushed the hardware to its limits, despite that, the developers didn't find vorbis to be a big enough resource hog even on such hardware
and modern games are the most unoptimized slop ever conceived by mankind
I will never believe that decoding a bunch of vorbis files is enough to cause ANY measurable performance impact on modern hardware running modern games.
It would only maybe make sense for footsteps or other sounds which are short and frequently repeated, but for that use case regular pcm wav is already more than fine, what is that quite okay audio format saving there, 500 kb on a 150 gb game? no point.
