The AMD Comressonator seems to be unavailable at the Moment (http://developer.amd.com/tools-and-sdks/archive/legacy-cpu-gpu-tools/the-compressonator/). Neither the 32bit nor the 64bit Version can be downloaded. The Webpage responds with an Error-Message:
Are there other places, where I can get this tool? Google found nothing. All other download pages link to the aforementioned URI.
I'd be glad to get some help on this, since the nvidia equivalent is a pain in the behind to use, since it doesn't seem to be able to generate mipmaps itself.
