I saw the same performance increase under the OpenGL backend for BGFX. With MAME 0177 being out in the wild, I will move forward to this version, but will keep your comments in memory.

(not mobile GPU)<br /><br />Initially I couldn't understand why BGFX seemed so slow still on such an improved hardware. After testing I found using artwork can greatly affect the fps with BGFX.<br />In the test case I was using, it was just a bezel with Elevator Action. Using OpenGL doesn't see to cause the same issues. <br /><br />estefan, can you see if you get the same drop in fps when using artwork/bezels.<br /><br />Results from testing:<br /><br />mame -video bgfx -str 30 -noafs -bgfx_screen_chains crt-geom -bgfx_backend opengl -artcrop -noreadconfig -nosleep -nothrottle elevator<br />Average speed: 85.58% (29 seconds)<br /><br />mame -video bgfx -str 30 -noafs -bgfx_screen_chains crt-geom -bgfx_backend opengl -artcrop -noreadconfig -nosleep -nothrottle -nobezel elevator<br />Average speed: 977.05% (29 seconds)<br /><br />mame -video opengl -nofilter -gl_glsl -glsl_shader_mame0 /Volumes/Emulation\ HD/MAME/Favourites/shaders/CRT-geom -str 30 -noafs -artcrop -noreadconfig -nosleep -nothrottle elevator<br />Average speed: 794.21% (29 seconds)<br /><br />mame -video opengl -nofilter -gl_glsl -glsl_shader_mame0 /Volumes/Emulation\ HD/MAME/Favourites/shaders/CRT-geom -str 30 -noafs -artcrop -noreadconfig -nosleep -nothrottle -nobezel elevator<br />Average speed: 791.79% (29 seconds)<br />Headrush69https://www.blogger.com/profile/01898418014927050348noreply@blogger.comtag:blogger.com,1999:blog-6213939121071879164.post-23260952894875059362016-08-15T00:13:18.732+02:002016-08-15T00:13:18.732+02:00For some reason my posts keep disappearing.

(At the cost of some minor visuals)<br />I saw a 4x improvement in Elevator Action, but the change in Marble Madness made zero difference. I'm sure there's a lot to do with the games native resolution too.<br /><br />Two things I'm waiting for with BGFX:<br />1) Changes made in game using sliders is stored.<br />2) We get some vector games effects like the D3D and HLSL renderers in Windows.<br />Headrush69https://www.blogger.com/profile/01898418014927050348noreply@blogger.com
