Remove tex_Sting_Aquaplus_tex.py from your noesis\plugins\python folder - I'll update the universal script sometime later.

UPD (Apr 13, 2020): universal script updated, please refer to this post.

The compression is the same but I don't see width/height anywhere

Not in C#, but Python (Noesis), maybe this could guide you.

Redownload the script from the 2nd post.

DXGI_FORMAT_R11G11B10_FLOAT actually exists and there is some use for it, according to this twitter thread

For Noesis. Download Noesis, place the file in noesis\plugins\python, then launch Noesis and try opening your files inside Noesis.

Because:
1) offset is 1E0
2) format is b8g8r8a8_unorm

Try these. Don't forget to remove all conflicting Noesis scripts.

UPD: reimport-friendlier QBMS script.

UPD2: QBMS script for tex-to-dds; Noesis script updated for more formats supported and Sting/Aquaplus LZSS (moderately slow vs QBMS script).
