I was talking about the offline compressor. I don't know what NVidia's
online compressor is like. Yes, perhaps if we can get a quick compressor
with reasonable results then it starts to make sense to compress on the

I'll take a look at using FasTC or Squish. However, it looks like both
of these libraries also support S3TC. If that's the case then would it
be a bit bad to have a hard dependency on one of those libraries? Maybe
distros would be reluctant to package those libraries if they are
worried about S3TC.

Yes, fair enough. As you say though I think it would be better to avoid
tying BPTC to S3TC so maybe this approach just isn't the right idea.
