I feel like some of the default bgfx shaders leave a lot to be desired. The hq2x-4x setting make the image look washed out and blocky and the xbr shaders seem to add large amounts of blur.
I remember zenju had a pretty good implementation of xBRZ with his modified version of MAME https://sourceforge.net/projects/xbrz/files/HqMAME/ but sadly hasn't been updated since 0.170 since ddraw is no more in the newer versions.

Anyone get shaders like 5xBR or xBRZ to work with MAME 0.177?
