Myst III don't running well on Pi3B+.

windg

RPi3B+
RetroPie 4.7.21 (install from Pi-Imager)
Official Psu
Pi keyboard and mouse
Scummvm 2.6.0, i try and 2.5.0

To make ResidualVM games run on the Pi3B+, because with the default settings they are crashing, i have to set Graphic Mode to OpenGL and Renderer Engine to Software.
Generally, the games running well with the exception of Myst III.
Game is running slow and the mouse moves and sound arechoppy. To be sure that it is not a limitation of Pi3B+ hardware i install scummvm 2.5.1 to bullseye desktop (with snapcraft) and the game runnig without problem.

The only log i found is when the game crash with opengl enable only:

Did you update the retropie-setup script to the latest version and tried to re-install scummvm. There has been an issue fixed ~three weeks ago: https://github.com/RetroPie/RetroPie-Setup/pull/3467 Maybe it solves your issue?

@lolonois
Yes, i have the latest updates. i try also a clean install but the result was the same. Thanks!

I have been setting up a pristine RetroPie install on a RPI3 B+ and made similar experience.
(Latest image from retropie.co.uk, updated ~/Retropie-Setup to commit 9569e179, origin/HEAD at the time of writing)

With the pre-compiled binaries installed from scummvm and default settings neither "Myst III" nor "The longest journey" start up. Segfault when trying to switch to OpenGL graphics:

This makes sense, as AFAIK the legacy driver 3D driver of RPI does not supply OpenGL.

Then I enabled the fake KMS for RPI3 in boot/config.txt (have dtoverlay=vc4-fkms-v3d enabled) but got "greeted" with a warning in retropie_setup.sh that this setting may break other emulators, so I reverted the change.

Maybe @mitu is there a way to solve this dilemma between enabling OpenGL on RPI3/Retropie and not breaking other emulators?

@lolonois said in Myst III don't running well on Pi3B+.:

That's not going to happen, sorry. If the game requests OpenGL (core) instead of OpenGLES, it's not going to work in the current RetroPie setup on a Pi 3.

Longest Journey is running well with renderer set to software, the problem is with MystIII. Anyway, it is only one game than doesn't run well on Scummvm for the Pi3, all others i have try are working fine.

Lolonois

@mitu thanks for setting this straight.
@windg yes, TLJ is playable, has some warnings with software renderer, but works. The residualvm integration into ScummVM has made large progress over the course of last year. :)
