@kingcosmuder thats all i got running the command however i tired some dreamcast using redream and both games i tried, sonic adventure and marvel vs capcom 2 both ran 60 fps consistently so i believe its working now

Hello , i have more problems GTA games , Vice City , Burnout dominator and some other i think the most recent PSP games boots fine and menus are ok.
But in the game the graphics are broken and unplayable. Cars and people falling trough the road and grass etc.
Same roms / dvd content are fine on ppsspp win10 desktop machine.

Tried vulkan on the PI4 but more and the same problems, also tried booting retropie standalone image and on twister os same result.

PI4 / 8GB
32 bit or 64bit kernal on twister os same problem.
ppsspp without retropie same problem.
Al on the latest updates of may 2021

Can anyone give some advise.

@gordonfreemanjr said in Amiberry 3.3 laggy:

I’m having the same issue with Amiberry: slow performance, choppy sound. I followed your advice regarding the resolution, but it didn’t work

Open a separate topic and add your system info, it doesn't seem to be the same issue.

@tuomaspap Sorry for the delay, I never expected a reply. I was able to get it through the wayback machine. I've gone ahead and found a link on github for the pi4, hope it works!

@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.
