60% is quite extreme. With a normal texture JPEG compression ratios should
be about 1:20 for 60%, 1:11 for 90% and 1:9 for 95% quality.
Zlib-based compression reaches 1:2 if you're lucky, so any of the three
ratios is very good. And with 90% finding artifacts is quite hard.

Only if you do tune your lossy algo to use extreme compression ratios.
