Windows performance can reasonably be seen as theoretical maximum, I hope I will be able to post benchmark values soon. -bench used to work with my packages a while ago, it is broken on 0.228 and 0.229 at least. ETA1: 0.224 package has -bench 90 working. ETA2: 0.226 package has bench working too. Let's check 0.227. ETA3: 0.227 is the last package with -bench resp. -str working as intended. 0.228 exits as soon as the rom gets loaded. ETA4: it is something in the ini mucking up the -bench/-str. I compiled git master with Code make -j6 PYTHON_EXECUTABLE=python3 NOWERROR=1 VERBOSE=1 REGENIE=1 SOURCES=src/mame/drivers/midwunit.cpp and the problem went away. As soon as I added -inipath to the command line, it came back. Any ideas what might be going on? Last edited by belegdol; 02/27/21 09:16 PM.

I figured it out - -bench/-str breakage was caused by autosave enabled in the ini. I am not sure whether this is intended or not but it is out of scope of the issue at hand. Now, back to benchmarks. With wayland I am getting:

Code

$ mame -video bgfx -bgfx_backend vulkan -nowindow -bench 90 -noautosave umk3
Average speed: 731.03% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -nowindow -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 54.73% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -window -bench 90 -noautosave umk3
Average speed: 748.82% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -window -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 444.91% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -bgfx_screen_chains default -nowindow -bench 90 -noautosave umk3
Average speed: 728.93% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -bgfx_screen_chains default -nowindow -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 109.12% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -bgfx_screen_chains default -window -bench 90 -noautosave umk3
Average speed: 739.98% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -bgfx_screen_chains default -window -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 640.75% (89 seconds)

It appears that it is the video output, scaling to full screen and hlsl screen chain killing the performance.

ETA1: same results when running under X.org:

Code

$ mame -video bgfx -bgfx_backend vulkan -nowindow -bench 90 -noautosave umk3
Average speed: 736.35% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -nowindow -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 113.99% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -window -bench 90 -noautosave umk3
Average speed: 734.86% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -window -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 447.35% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -bgfx_screen_chains default -nowindow -bench 90 -noautosave umk3
Average speed: 741.29% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -bgfx_screen_chains default -nowindow -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 657.48% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -bgfx_screen_chains default -window -bench 90 -noautosave umk3
Average speed: 744.40% (89 seconds)
$ mame -video bgfx -bgfx_backend vulkan -bgfx_screen_chains default -window -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 684.39% (89 seconds)

Unsurprisingly, the -bench runs are more or less the same speed. Scaling to full screen is what appears to cause a huge performance hit on wayland as using hlsl or default screen chain appears to have the same cost on both X.org and wayland when running in windowed mode.

ETA2: Switching the bgfx backend to opengl yields the following on X.org:

Code

$ mame -video bgfx -bgfx_backend opengl -bgfx_screen_chains default -nowindow -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 677.78% (89 seconds)
$ mame -video bgfx -bgfx_backend opengl -bgfx_screen_chains hlsl -nowindow -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 152.49% (89 seconds)

and the following on Wayland:

Code

$ mame -video bgfx -bgfx_backend opengl -bgfx_screen_chains default -nowindow -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 676.23% (89 seconds)
$ mame -video bgfx -bgfx_backend opengl -bgfx_screen_chains hlsl -nowindow -str 90 -nothrottle -sound none -noautosave umk3
Average speed: 152.66% (89 seconds)

So opengl backend performance appears to be independent of which windowing system is being used.

I ran the test three times. The numbers were continually within margin of error across the three runs for MOST of the tests, with only a few FPS difference at most on those. As a result, I'm going to provide only one set of numbers to avoid this post getting any spammier than it already is. Note that I manually forced mame.exe to go to the AMD iGPU instead of the NV one.

Code

BGFX Vulkan 
mame.exe -resolution0 1920x1080 -video bgfx -bgfx_backend vulkan -bgfx_screen_chains hlsl -nowindow -str 90 -nothrottle -sound none umk3 
Average speed: 323.60% (89 seconds)

It seems like BGFX has absolutely weird discrepancies in the results of "vulkan", though. I got a really high speed on one occasion, others it's maxing out at 109.65%. This is particularly weird as nothing has changed between runs, and it will show the extremely high speed at seemingly random maybe one out of ten or so tried.

Code

Average speed: 323.60% (89 seconds)
Average speed: 109.55% (89 seconds)
Average speed: 109.55% (89 seconds)
Average speed: 109.55% (89 seconds)

Which is actually turned on, so that would have absolutely affected performance. That's embarrassing! I'll revisit these benchmarks while I'm off in physical therapy and post the results when I get home. Sometimes the obvious thing is right under your nose and you can't even see it. Edit: I've got it running three passes on the current official release and a current in-progress build from last night as of now. Last edited by Firehawke; 03/01/21 06:01 PM.

Made sure to check vsync, which was actually off for the last official release and on for the in-development branch (and was turned off at that point)
Here's the results. Without looking too closely, it looks like there's not a lot of difference there though it's interesting that BGFX's auto doesn't choose the best backend with the Vega iGPU.

Don't think I'm going to be able to squeeze anything more out of this on Windows at least, but on Linux there could be some definite driver issues.
