Input lag on new build, any help?

HansP

Hello,

i get mixed results when searching for input lag issues on the retropiesystem with RPI3

i bought a system with 2 nes controllers and also tested with keyboard and additional PS3 copy controller for PC
All input devices give me a slight inputlag when pressing a button

it really affects the gaming experiance and i checked some settings but untill now i did not find what to do after googling for a long time about the issue.

anyone has another idea what to do?

used a LG 42inch LED TV at my parents home
Panasonic Viera 55inch Plasma TV
Dell 1920 4:3 screen @home

Hi

My bad

Pi Model: 3b
RetroPie Version Used: 4.1
Built From: ISO from Retropie to SD
USB Devices connected: Keyboard, 1 SNES controller USB
Controller used: SNES
Error messages received:
How to replicate the problem: Games in SNES and SEGA Genisis have an imput lag of a few ms ( cannot measure exact amount )
but pressing button to jump, the character response when button is released ( if you just tap it )
Keyboard gives exact same lag

Not important i guess...
Log found in /dev/shm/runcommand.log (if relevant):
Guide used: (Mention if you followed a guide)
File: (File with issue - with FULL path)
Emulator: (Name of emulator - if applicable)
Attachment of config files: (PLEASE USE PASTEBIN.COM FOR LARGE LOGS)

@HansP Which emulators you're using is pretty important information mate. You can find out which by pressing a button as a game is loading to get into the runcommand menu where the default emulator you're using for each system should be listed. There have been a few forum posts about input lag already in snes emulation so it'd be best to search the forums as well to see if anything has already been covered there. I've not experienced any myself but I'm sure with some extra info the forum members may have some help for you.
