Crunch2 VS compressonator

After spending some time trying several libraries, I settled with FasTC for now, but it seems to only be able to manage 32 bits RGBA image formats... I am looking into Crunch2 which is basically Crunch with modern CMake.

AMD’s Compressonator utility (https://github.com/GPUOpen-Tools/compressonator) is free and can provide much better image compression. It provides settings for adjusting the desired compression quality (better compression = slower). It can run either on CPU or GPU, though GPU will be faster, especially for BC7 compression. It works with my Nvidia card, so you don’t necessarily need an AMD card to use the utility, but YMMV depending on the GPU you’re trying to use.

If the answer involves texture formats for some odd reason compressonator is a tool worth looking into, its kind of incomprehensible, but check the releases page anyways, I think you want the GUI one

Hey, thanks for the answer, I went to try loading up some textures that I compressed with BC4 and BC5, using Compressonator from here: https://github.com/GPUOpen-Tools/compressonator

DynDOLOD will run but will not be able to compress any of its textures. You will need an external tool for that. ROCm's compressonator seems to work just fine for BC7, just need a bit of fiddling

In the first topic it also mentions saving your edited dds files with conpressenator to achieve better quality, I don’t remember where I got that program but here is one link to it, I think I got the earliest release on that page.
