What should happen

months ago, ca 3 or 4 months, there were no tearing in the games and i could switch from default 30fps games to 60fps. today i tried to play a game, and saw the tearing andd testet more games, and saw they are all running at 60fps and unter options there is no option to switch from 30fps default to 60fps and back. but i know there was a option for that months ago, because i tested the games how the are running. what happend? why it was removed?

15210 forced that setting to always render duplicate frames to fix some audio path issues.

The libretro interfaces were really designed for weaker systems (the SNES is 1% the power of the PSP, the PS1 is 10%), and so libretro does timing based on audio (a path we already tried years ago and moved away from because it works poorly for PSP emulation.) It's also hard for them to change the interfaces because so many of the weaker systems that emulate fine that way would have to be reworked.

PPSSPP runs slower and less smoothly under libretro, so I would recommend running PPSSPP proper.

That said, maybe the setting can be restored so you can choose between audio issues and tearing. You might also be able to adjust settings in your graphics driver to affect vsync/tearing.

the tearing i have only with ppsspp libretro with retroarch. no tearing problems with duckstation or flycast or any other core wich i use. so i think this setting for always 60fps is the cause of the tearing, because with ppsspp standalone, i have no tearing and months ago also not with retroarch.

The d3d11 of retroarch has an option VSync Swap Interval,The official description is: Use a custom swap interval for VSync. Effectively reduces monitor refresh rate by the specified factor. 'Auto' sets factor based on core-reported frame rate, providing improved frame pacing when running e.g. 30 fps content on a 60 Hz display or 60 fps content on a 120 Hz display. If ppsspp can be well connected with this option,I think, maybe it should be able to solve the problem of this topic perfectly.
