Hi all,

I’ve been trying to modify the command buffer size for our game. I’ve found multiple threads on the advanced settings, and how to change them, but I can’t get my script to run before FMOD runs its initialization code. Even setting the script all the way at the top of the execution order list doesn’t do the trick.

Any ideas? Thanks!

Hi,

You can use the Callback Handler scripting example to assign the settings: [Unity Integration | Scripting Examples](https://fmod.com/docs/2.02/unity/examples-callback-handler.html).

Hope this helps!

I’ll give this a go, thank you!
