Is BC5 higher quality than DXT5 NM Compression?

[anonymous_user_6bb7d60a]

Interesting question, I don’t know it personnaly but by going on MSDN forums I found that :

BC5 -> Two-channel color	Two color channels (8 bits:8 bits) 	Direct3D 10

this looks interesting too :

Edit: from what I’m reading DXT5 should be faster but uses a more agressive form of compression
