MAMEWorld Forums - EmuChat - Questions about bgfx on mameui64

Hi

I am afraid I have some noobish questions about bgfx...

Could you please help me clear some confusion?

-What is the difference between using HLSL "directly" and using it through bgfx (as a bgfx_screen_chains argument)? Is one better than the other?

-Which backend is the best on windows (best being relative):
d3d9
d3d11
opengl

-Should I use bilinear filtering with bgfx?

-I mostly play neo geo games at 1080p using bgfx and CRT geom deluxe, what sort of monitor were used in arcade? I would like to emulate them as best as possible when it comes to the numbers of scanlines, the shadow mask...

Many thanks. I have spent a while searching online but a lot of info is contradictory...
