gba,snes seems a lil laggy+sound issues

SmellyViking

seems the lr-gpsp (gba) works smooth but some odd games dont run
like the classic nes series games but anything that does run looks and sounds great

@smellyviking A temp or lightning bolt icon might cause the slowdowns. If you messed with the video config or using a 3rd party image can also cause this.

thank god!!!! im having REALLY bad sound issues with ALOT of my snes games,, ive tried every snes emulator its only snes for me... but the audio is very crackly, laggy, stutter i just overclocked it to 1.4 to see if itd fix it and NOPE no luck

@smellyviking people keep saying its in my settings but its not.... my settings were fine... NO ONE can figure this out its annoying

Taken from [https://github.com/RetroPie/RetroPie-Setup/wiki/Speed-Issues]

Edit /opt/retropie/configs/all/retroarch.cfg and set:

Use threaded video driver

video_threaded = true

Smoothens picture with bilinear filtering

video_smooth = false

Audio driver backend.

audio_driver = alsathread

Enable rewinding

rewind_enable = false

For me, setting video_threaded to true, fixed a lot of my speed issues. Results may vary though.

@scooter1974 All of those settings from the wiki are the default, so either you changed them yourself or using a 3rd party image and those aren't supported here.

@darksavior Its not a 3rd party image, for sure. Perhaps I turned off threaded video without thinking, which is entirely possible lol.

quoting edale in this oldish thread:

"Oh, and it actually takes a 3 GHz CPU to perfectly emulate an SNES, due to architecture differences and timing issues (yes, I know, the SNES was only ike 33 MHz). A Pi 3b only has 1.2 GHz CPU. Most games will run fine, but almost none will run perfectly."

hmm

@smellyviking The fact snes9x runs fullspeed with all games for everyone else , that quote doesn't apply to these emulators. You only need a 3ghz+ cpu for bsnes or higan, which are not available for the pi. If a game does run slow, you'll either have to overclock or use an older snes9x....if you have a perfectly working setup which you don't have...

Whoever could solve the problem with sound on SNES emulator PI3B, PI3B+
The solutions described "https://retropie.org.uk/docs/Sound-Issues/" do not work.
Very disappointed in Raspberry.
Sound sometimes slows down and collapses.

a few days later .... after reading a lot of unnecessary information
The problem was in throttling.

avoid_warnings=2 means don't show the warning squares and don't disable turbo mode on under-voltage condition. We still throttle on over-temperature.
