Citra Nightly lag

For me, Citra Nightly is really laggy and the counter reads 0 FPS a lot. Whenever I start a new level, something big happens, when I try to save or load a save state (loading especially), the emulation freezes and it shows 0 FPS for a bit, before it goes back to normal. This makes gameplay extremely inconvenient and stuff.

Here’s some issues I found with your log that might help.

Save States aren’t meant as a replacement for normal in-game save files. Save states are meant to be used within a given gaming session, but not beyond them.

Save States also regularly break across different Citra versions so you should be careful with loading old save states on newer Citra versions.

As for your issue in particular, when saving or loading a state, it’s basically saving or loading the state of Citra entirely all at once (not just the game) → Which is hard on your system. This is unavoidable and it can only be mitigated somewhat when you’re using very powerful hardware. Sorry for the inconvenience.

Thanks, but I’m not only talking about save states. I’m talking about the whole emulator itself. Everyone says it works perfectly fine, but for me it’s so laggy I almost can’t play at all.

MacOS seems to have issues with some of the recent changes made in Citra. Perhaps your issue is related to that. Please try out this older Citra version to test this:
Download citra-osx-20200707-bd7ee8c.tar.gz from Release nightly-1587: Common: remove a mod from AlignUp (#5441) · citra-emu/citra-nightly · GitHub
Extract it and then run the citra-qt executable found inside of the extracted folder

Thanks! This helped a little, but I’m at least glad I don’t need to wait 5 minutes for the game to start. :slight_smile:
