@mitu said in Amiberry 3.3 laggy:

@frozen That should work also, just remember to remove the comment marks (#) from the beginning of the line where the option is set in config.txt.

oh.. now when i remove '#' marks it works ! :) smooth and nicely, thanks a lot

@emk530 I upgraded to latest 4.7 and having exactly the same issues with you but on the Pi4.
Can't find the image of 4.6 though anymore :( Is there somwhere you got it from that you could share link ?

@UberLumby Look at least my version of raspberry:)

Actually, it did work but instead of adding these lines I uncommented the same in the config file and just changed the values. Thank you very much for you fast and adequate response.

@quicksilver

Thanks for this I may look into it. Thanks all for the assistance!

Use the default retroarch.cfg - leave aside all the hard sync settings (I don't think they're relevant for the Pi's GPU) and the audio settings. Also, a GPU mem of 256 is more than enough for most emulators, so I don't see any point in upping it to 512.

Try gpsp's non-retroarch version. With this version, you'll probably have less lag on GBA games, since it consumes less resources than the default retroarch version.

I've tested this version on a Raspberry Pi 1 B+, and I remember playing some GBA games without lag. It was on 2015, and back then, if my memory serves, there was no lr-gpsp yet.

I don't know if it'll work on your Pi Zero, but assuming Pi Zero and Pi 1 has approximately the same hardware, there's the chance that it can work.

@washburngopro

That might be run-ahead instances. I think the setting is found under "latency".
Could set it to zero, I never use it but it is okay with some Nintendo games.

The bios is good, you should keep it. Rarely (Arc the Lad Monster Tournament) do I ever have to use no bios.

If your pi doesn't have any heatsink, airflow, cooling fan, radiator. It will overheat and the SoC/CPU will throttle undermining performance in some games. While it is possible to underclock and increase the soft/temp limit to get adequate performance for PSX, good ventilation is still needed when playing 4+ hours.

@lesk Deopending on the emulator and version I think, as it is a relative recent feature. You may need to update RetroPie. There are entries in the emulator menu for this feature: SETTINGS > LATENCY. I looked up in Snes9x 1.56.2, Nestopia 1.50-WIP and MAME 2003 (0.78).
The Raspberry Pi 3 is too weak and it would be extremly slow and painful (as far as I know). Which emulator and version do you want use this for? Try the "lr-" versions.

Thanks, I'll try it!

Have a look at this article about hdparm! There are many settings you can tweak!

You could also set the sleep/standby timer to a longer time!

@IanDaemon i found that when I'm in game and I bring up the retroarch menu, I can't move anything in the UI. The cursor will not move with keyboard or controller. I'm stuck there until I hard reset the pi because I have no input. I thought about a reinstall but I spent a lot of time scraping and setting up and I'd hate to have to do it all again.

@chubsta It's definitely the images causing an issue, especially if you have a lot of games. All of my Pi Zeros have this issue and I no longer use the videos. If you try another theme or change the UI theme settings to BASIC (I believe) you should see it become very responsive. The Zero is a minimalist board when it comes to resources but it functions extremely well for all of the systems I run on it.

@sebretro said in Periodic stuttering/freezing with RetroPi4.4 on a Raspberry 3B+ in every game (1-2seconds):

Does anyone have know about this problem? Thank you for your help.

Looks like an insufficient power problem - the RPI underclocks itself not having enough power. Take the PI out of the case and do some testing to see if you get the same problems. The NesPI cases are notorious for this kind of problems.

@thelostsoul

The supported tweaks also yield the best results by far. Setting a television to game mode alone feels like the difference between night and day. Setting even all of the possible unsupported tweaks feels more like the difference between night and a bit later that night.

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.
