Title: MAME 0.172 BGFX shows black screen for raster games only
Post by: Nocturnaloner on April 04, 2016, 05:06:41 pm
After a lot of tweaking and mistakes on my part, I got the HLSL sliders to appear for BGFX video mode.  I started with a fresh install directory.  Raster games play with no visuals (black screen), but all sounds and interaction work as normal.  Vector games are fine.  One thing I do notice is that when running a raster game from command line, I see several 'optional missing' errors like 'palette' and 'bankc000' and 's2650_spriteram', etc..  I have Directx11 and the DirectX9c runtimes installed.  CPU is an i5, 3.4ghz.  Graphics card is a GTX 650.  Win7 64 bit.  Do these errors seem like the cause of the issue, or is there anything I can do to learn what the problem is? .ini file attached.

By the way, I just discovered that 'bgfx_backend opengl' works.  Now, why doesn't DirectX want to work, either 9 or 11?

After installing 3DMark, BGFX ran with no problems.  Could be a coincidence, but I'd installed DirectX 9 in both the web installer and redist versions, and the problem didn't stop until I installed 3DMark, just to see if DirectX was working at all.
