Input lag comparison between SNES Mini and Raspberry Pi with Recalbox

[daminoutav]

I have both of them + NES Mini, and I have no (or I can't see any) difference on my PC screen (1ms)
Do you use a dongle or the internal bluetooth ? The last one could be the root of the problem.

@marcdk if there was a magical recipe to reduce the input lag, we'd have done it as default

Give a try to changing the video renderer to dispmanx. To do so, edit your retroarchcustom.cfg and add video_driver = "dispmanx". No need to reboot, just start a game

Thank you. I'll try.

Are you sure about the "? Shouldn't this be

video_driver = dispmanx

[MarcDK]

I tried

video_driver = "dispmanx"

in /recalbox/share/system/configs/retroarch/retroarchcustom.cfg

with no noticable impact. Any other idea or is this the point, where the SNES Mini is plain better?

Except recompile the kernel with real time patches, no

What about this thread: https://forums.launchbox-app.com/topic/33911-retroarch-input-lag-settings/

video_driver = "dispmanx" ("gl" if you require 3D acceleration or shaders. Will add one frame of input lag compared to dispmanx driver.)
video_vsync = true
video_threaded = false
video_frame_delay = 0

video_threaded = false is not set. My the odroid be an answer? Have you tried it yourself with a SNES Mini and a NES Mini or Real Hardware in comparison?

@marcdk which board are you using ?

[MarcDK]

Raspberry Pi 3. But I think there is nothing you can configure on a pi to change the input lag of appr. 3 frames according to this thread: https://retropie.org.uk/forum/topic/2019/an-input-lag-investigation/36

Every emulator has a lag. Even BSNES.

@marcdk anyway you can manually set these values in the retroarch configuration files if you wish to test them.
