Question for exporting to ogg

Hi all!

I work on game audio and I'm currently working on a project that needs several tracks to play at the same time (I'm using FMOD to add all the logic that the game will use). I'm exporting all my tracks to ogg because wav would consume too much space and cpu power, causing the timings to be off and other glitches.

With the last track I made, it seems like even as ogg, some problems occur. I don't want to sacrifice sound quality too much. I noticed that no matter what bit depth I select, the ogg is always saved at 32-bit. Is there something I can chage to make it 16-bit or is that something innate to ogg itself?

Thank you!
