MAMEWorld Forums - EmuChat - Re: Vsync/Frameskip Causing Horizontal Motion Blur

Below are my settings for D3D and for BGFX. If you haven't tried BGFX I recommend you try it as an alternative. I just realized that with D3D, when video scrolls smoother than BGFX, which is what I've been using for the last few months. I tested this on the first stage of Shinobi.

As with everything emulation, your mileage may vary.

Code:


#
# CORE PERFORMANCE OPTIONS
#
# With BGFX refreshpeed=1 does not work correctly but autoframeskip=1 prevents sound hiccups in galaga, mspacman and other >60Hz games
# This bug for BGFX is confirmed by mametesters bug ID#06346 from Sep, 2016 and is still open
autoframeskip             1
frameskip                 0
seconds_to_run            0
throttle                  1
sleep                     0
speed                     1.0
# Enable refreshspeed when using D3D to avoid sound hiccups on games >60Hz like galaga
# With BGFX, it doesn work correctly and the hiccups persist, so no harm in leaving it on with either renderer
refreshspeed              1

# OSD VIDEO OPTIONS

video                     bgfx
#video                     d3d
numscreens                1
window                    0
maximize                  1
# Triplebuffer is supposedly preferrable to waitvsync but only works with D3D
# Some from of sync is needed to avoid tearing/microstuttering (as in the 1st stage of shinobi) so use waitvsync with BGFX
waitvsync                 1
syncrefresh               0
monitorprovider           auto

#
#
# FULL SCREEN OPTIONS
#
# When using D3D, triplebuffer is preferable to waitvsync but it doesn't work with BGFX
# There is no harm to leave it enabled with either renderer
triplebuffer              1
full_screen_brightness    1.0
full_screen_contrast      1.0
full_screen_gamma         1.0

If BGFX gives you good results, I highly recommend trying out this built-in CRT shader for a CRT look:
