BGFX performance issues - solved?

For anyone who's had performance issues with the BGFX renderer since it went in, can you try the latest code that's in github? I've done a lot to improve performance of the plugin. Some before/after reports would be great.

Peak performance displaying game video only is the same or possibly marginally better, but now displaying the OSD UI (tab menu, sliders) causes no drop in performance whereas previously it took a 75% hit. Looks like a huge improvement for drawing UI elements.

Transparency of UI elements over other UI elements seems to be busted. For example if you run "mame -video bgfx" then select a game from the list that you don't have a full ROM set for, the error message is unreadable. It works properly with -video opengl and -video d3d.

Thanks. I'll have a look.

It seems to be working ok, but the games run really slow. About half there normal speed. Is there a setting I can configure to make them run at full speed?

Do you have vsync, triplebuffer, matchrefresh, or any other non-default setting turned on? Post your mame.ini.

Can you try the latest code in git? It should work now.

I figured out what was causing the games to slow down when using BGFX. Maybe this is a known issue, but when I have artwork enabled, the games slow down. Sometimes to half the speed. But disabled the games run at full speed.

I'm noticing this also on some games...boothill for example. The speed is dropped if all artwork settings are on but returns to 100% if crop, backdrops or bezels is off.

Can you point me at a download link for a full artwork set for boothill? I'll slap it at a profiler and see what shakes loose.

I use PNG effects overlay files over BGFX (yup) and I've noticed the considerable drop in performance, indeed.
Games running at 75% speed because of a minuscule PNG overlay ? Seriously ?
Turned out in my case it was a matter of wrong GPU used.
I have a computer that allows to switch between the weak intel iGPU, and a significantly better geForce, you know that 'optimus' thing.
Naturally it'll always automatically pick the wrong one, so I've forced MAME to use the geForce and everything was back to normal speeds, even a bit better in some games (cv1k for instance).
Seems you can't run BGFX on anything and get similarily good performance ratios in every circumstances; e.g. that intel igpu weakness with overlays.
