Ah, that's likely because I have to decompress the BC1 textures and all mips to RGBA8 which takes up quite a lot of additional texture memory, since I don't believe BC1 is supported on iOS. I remember crashing on some Dark Souls maps on PC before I added support for WEBGL_compressed_texture_s3tc.

I might be able to do some memory improvements to the BC1 decoder right now as well; thank you for the heads up, and I'll add it to my list of things to investigate.
