how to make LS use in game fps in emulators rather than screen fps

[harsh turtle]

yesterday i managed to make LS use the emulators fps (25) to go to 60 fps which looked great, but today it switched back to using the screen fps (165) which look less smooth, idk how to make LS use the emulator (duckstation) ingame fps again.
for example it used to be 25/60 and now it's 90/60

ryzen 7 9800X3D and Radeon 9070 XT
here's the settings i use

@harsh turtle - Overlays are a common culprit that lead to failure of window capture.
This leads to LS detecting a different framerate than the game outputs, oftentimes your monitors refresh rate (e.g. 144/144)
The most common culprits are Discord, Nvidia Shadowplay, AMD Instant Replay or even a duplicated display.
If you are on Windows 11 24H2 or newer you can mostly mitigate that by just switching to the WGC Capture API in the LS settings.
For more information on troubleshooting, refer to:

tried switching to WGC and closing discord but nothing

instant replay is also deactivated

Have you deactivated the Discord overlay?

Closing Discord also doesn't really close it unless you changed that in the settings specifically

[harsh turtle]

discord doesn't pick up the emulator, so no overlay

ok i deactivated the overlay entirely and now it's 50/60 instead of 90/60 so it's better ?

So it was the Discord overlay

but yesterday it was 25/60, kinda weird, i also didn't touch any of the emulators settings

well thanks for the help

Maybe it has some kind of dedup

Doubling the output FPS

Look for a setting in the Emu maybe

[harsh turtle]

ah yeah found it, it was the "skip duplicate frames" settings

back to 25/60 now

thanks
