That's horrifying. Is there any way to disable the GC and manually manage memory? I don't remember if the C# spec supports this, because it's been years since I've written in it (and Mono didn't exist back then).
So there is... using the "unsafe" pointers and fixed keyword, etc. The Unity interfaces don't support that, though, so for things like dynamically updating textures and vertex data, you're pretty much stuck with GC.
You "disable" the GC in Unity by never allocating anything new after initializing the game. It's a great learning experience to update code to this and it's practically required for mobile.
