I agree with you, "NVIDIA Texture Tools Exporter 2024.1.0" gives much better quality than "texconv.exe" when converting from BC7 to DXT5 (BC3_UNORM_SRGB) using same settings.

@suphamster Why would you convert from a higher quality compression to a lower-quality compression and expect good quality?

I've attached zip with 3 dds files to compare (original BC7, "NVIDIA Texture Tools Exporter 2024.1.0" and "texconv.exe" both DXT5). I expect resonable quality after compression without much loss (look at red car front) that happens after using texconv.exe in my case.
Upd: "-bc u" parameter makes image better (removes pixelation in some cases) but still not so good as using NVTTE (that has features like gauss blur or smoothing to get rid of blocking artifacts),
