I finally got access to an NVidia card last night so I've added an image
from their online compressor to the bottom of that page.

Hi,
I had a quick look at using libsquish and FasTC.
I didn't manage to build the libsquish repo¹ that Matt Turner pointed to
before giving up. It looks like the SSE version of the compressor is
using some MSVC-specific intrinsics which don't build with GCC. It seems
to be using members of __m128

That sounds like a fun project. It would be a shame to have to
completely decomp

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

Here's a first attempt at a patch series to implement BPTC texture
compression in the i965 driver on Gen>=7.
Getting it to work on the hardware is pretty trivial as it's just a
case of adding some new Mesa format enums and then plugging them
together with the right Intel surface type. However GL r
