< 30 FPS, Can't get games running smoothly on Raspberry pi 5 (Rodland, Gods, New Zealand story)

I'm running at 1080p as far as i can tell.

It'd be a good idea to be sure, being locked at 30Hz when using 4k resolution is a well-known issue.

@danturn I made the switch to lr-puae2021 recently on pi4/pi5 on Bookworm.
Had to adjust a few core options initially, but plays well.

@barbudreadmon thanks for that, so... i have set video=HDMI-A-1:1920x1080M@60D in my /boot/firmware/config.txt file.... when launching the game in amiberry it also has 1080p selected. Is there a way to double check?

worth mentioning that my monitor is 1440P not 4k, so it would never run in 4k anyway

one major annoyance is that if i press f12 to change game config to experiment, when clicking reset / resume both my controller and keyboard stop working so i have to hard reset the pi, not sure if anyone has any thoughts on that?

any other raspberry pi 5 users out there with any tips that they used? i've just done a stock install onto the SSD, installed amiberry and moved the roms in.. :(

danturn

@RapidEdwin08 ok thanks, i might check this out... did you change due to issues with amiberry?

danturn

Ok, i did a full reinstall this morning... followed this:

https://github.com/danielfreer/raspberrypi5-retropie-setup

then i copied roms from amigaforever and the rodland.lha into the folders...

i then followed this advice from @mitu

You can force a boot resolution using the video parameter for the kernel boot, like any other KMS platform - see https://wiki.archlinux.org/title/Kernel_mode_setting#Forcing_modes. This means adding to the in the cmdline.txt file from /boot/firmware (NOT config.txt) the video=HDMI-A-1:1920x10280@60 parameter at the end of the line .

rebooted and have the exact same issue :( <30 FPS, ultra slow performance and if i press F12 and then resume, the keyboard and joypad stop working

i tried out recalbox and with the same bios + rom (and seemingly the same config in amiberry, it all works at 50FPS as expected.. :(

Yes actually, and I was only playing SuperOffRoad and Lemmings...

I found an older Binary I built on RPi5 Bookworm back in December.
Maybe give this a try and see if the results are better than what you're getting now...

Amiberry v5.7.2 202412

pkg_origin="source"
pkg_date="2024-08-05T16:57:07-04:00"
pkg_repo_type="git"
pkg_repo_url="https://github.com/BlitterStudio/amiberry"
pkg_repo_branch="v5.7.2"
pkg_repo_commit="d4418a16827d0edd619874405d990725b908b82a"
pkg_repo_date="2024-06-06T16:22:44+02:00"
pkg_repo_extra=""

Just replace the files as needed and make the binary/sh executable (chmod 755).
I have not gone back and tried this binary myself, but curious what your results are if you do.

Here's an older Module script for v5.6.6 too if you want to try (don't forget the amiberry/*.diffs)
RetroPie 4.8.6 Amiberry v5.6.6 Setup Script

Edit: To be clear I've been using [video=HDMI-A-1:1920x1080@60D] in my cmdline.txt since day 1 on RPi5

@danturn Going back to Amiberry v5.7.1 works as it did before with no issues for me.
For the record, I tried both preview-v6.3.3 + v5.7.2 on my Pi5 Bookworm64 and both had the issues you described.

Easiest thing to do would probably be to just change the version in the RetroPie-Setup script.
/home/pi/RetroPie-Setup/scriptmodules/emulators/amiberry.sh:

#echo "v5.7.2"
echo "v5.7.1"

So apparently it's not a bug, sometime last year amiberry had an update (i think it has to do with modded amiga emulation ?) which forced disabling JIT support on arm, hence the performance dropping.
They made a fork without this update where JIT support is kept : https://github.com/BlitterStudio/amiberry-lite
I guess it should be added to retropie setup scripts ?

Not surprising, for better or worse, recalbox often use outdated emulators, in this case they are using v4.1.6 from 2021.

The version installed for ARM is from before the split happened, as far as I know.
