RetroPie on the Pi 5 - what's left to be done?

sugarfree

Most of the games should run without issues, with some exceptions, such as Die Hard Arcade and Virtua Fighter. Sega Rally runs fine most of the time at 60 fps, with a few moments in some races that experience frame drops for a few seconds. What resolution are you using?

Vulkan doesn't work well with this emulator so the driver is not the issue.

The result was not the one you were spoking of: it was similar to N64 on a Pi3: scrolling lags, bad audio,.... :/
This is spoken for running this emulator out of the stock: did you change anything to get this flawless performance?
Do i have to install this infamous "Vulkan"-driver?

Jumping in. I'm using GL and lr-beetle-saturn is very solid. 60fps, no stutter with Sega Rally Championship. No overclock.

If you are running in 4K, change to 1080P. There are threads around here to advise. Also avoid any heavy shaders.

Here are my RetroArch Video settings. Might want to compare:

Retroarch --> Video --> Output

Video gl
Threaded Video True (on)
Screen Resolution 1920x1080

Retroarch --> Video --> Synchronization

Vertical Sync False (Off)
Hard GPU Sync False (Off)
Max Swapchain Images 3
Frame Delay 0
Automatic Frame Delay False (Off)
Sync to Exact Content Framerate False (Off)

Retroarch --> Video --> Fullscreen Mode

Start in Fullscreen Mode True (On)
Windowed Fullscreen Mode True (On)
Fullscreen Width 1920
Fullscreen Height 1080

Hope this is helpful.

Hope this is helpful.

On-topic, I don't think there is more to be done with this emulator or its configuration. For me, it's been rock-solid.

@Vermont which solution would allow me to quickly get on my feet with a couple Dreamcast games, while allowing me to have access to a temperature output so I can test my cooling system?

What resolution are you using?

I am using 1920x1080 @60Hz at 4:3 ratio for all emulators.
Plus the "ZRT_CRT_fast"-Shader.
I will deactivate the shader and have a look what happens in the evening :)
As it runs perfect at your setups i am pretty sure that is something wrong with my installation.
Even more as i realized yesterday that the performance of Amiberry is much worse than on my Pi4 or even Pi3...that cannot be true, there is something wrong indeed.
On the other side DC and PSP do run much better, so it is not a faulty CPU or something like that.

Thanks a lot for your support guys, i keep on tindering ;)

I uploaded my backup RPi5 image a few days ago. If you can try and with it and make sure that you have the official PSU for the Pi5

To be honest....i wanted to use your image indeed :D
But i could not download it from this Microsoft-Cloud, i had a fully working internet, every device had full connection, but this cloud told me "problems with the internet connection".
After 3 tries i canceled that download and decided to install manually ^^

I have the genuine Power-Supply & The genuine cooler-system, it has to be something in my software-setup.
I will try again this weekend, i am still very relaxed.

i did not really play amiga-games, i just have them because i had a real machine as a kid
i never had a saturn, so the emulation is just the cream on the cake, but not really important to have
i like to solve problems :D

I just recognized another issue that i never had before ;)
Oddly it just concerns "lr-ppsspp".
It is about the saving of the "current configuration" of Retroarch.
I use this because i change 2 things in every libretro-emulator: acitvate the conformitation of the exit (push hotkey twice to exit game) and set the apperance of the GUI to "dark grey".

This has never been a problem at all, but with my ne Pi5-project the saved configuration is...kind of "instable".

Example:

The first time i do these steps the configuration-file is saved as "/opt/configs/all/ppsspp/ppssp.cfg" (hope the path is right, but in the end it is all about the filename itself)

When i start lr-ppsspp again, the saved configuration is not loaded.
And when i repeat doing the saving of the current configuration file it is saved under "/opt/configs/all
/ppsspp**_01**.cfg"

And so it counts on...i am at "ppsspp_72.cfg" now i guess :)

In the end RA does not keep/like the saved configuration-file and wants a new on with every start :/

Does that sound familiar to anyone? I have no idea where to start investigating :/

thx & have a nice weekend!

EDIT: affects also lr-melonds and lr-flycast...maybe it is some kind of corona-virus, which infects all my emulators :)
In the end i stopped creating new RA-config-files it sucks atm, waiting for updates/bugfixes ^^

Ok, this is a general problem: have a look at this (am i the only one testing Amiga on a pi5? :D):

Frequently Asked Questions
Q: On Debian Bookworm, the performance when running in Full-Window is terrible. But it's much faster in Windowed mode. What is going on?
A: This is due to SDL2's choice of back-ends. The current versions seem to prefer X11, even when Wayland is used in the system (Bookworm is using Wayland by default). You can override this manually, by telling SDL2 to use a specific back-end, or change the order of priority it should use. Alternatively, you can switch to X11 instead of Wayland (read further to see how to do that).

First, test running Amiberry like this (from the terminal): SDL_VIDEODRIVER=wayland ./amiberry Does this fix the performance issue while in Full-Window modes? If so, you can make this change apply whenever you login, by doing the following:

Open a console, and type sudo nano /etc/profile.d/sdl2_fix.sh - provide the root password if requested.
In the text editor that opens, type the following:
#!/bin/bash
export SDL_VIDEODRIVER=kmsdrm,wayland,x11
Press Ctrl-X and then Enter (or Y), to save the changes to the file.
Log out and log back in, for the changes to take effect.
If you prefer to switch to X11 instead, you can do that by going to raspi-config -> 6 Advanced Options -> Wayland -> W1 X11 Openbox window manager with X11 backend.

@administrators I would be interested in that too?
