Game Name?

The Legend of Zelda: Ocarina of Time, The Legend of Zelda: Majora's Mask

Game ID? (right click the game in the game list, Properties, Info tab)


MD5 Hash? (right click the game in the game list, Properties, Verify tab, Verify Integrity button)


What's the problem? Describe what went wrong.

A stutter (around .5 seconds) occurs about every 8-9 minutes of gameplay, sometimes when loading an area, when opening the menu but sometimes seemingly out of nowhere. It is not a stutter present in the original VC version. Changing settings did not seem to alter the issue in any way.

What steps will reproduce the problem?

Playing normally for at least 10 minutes

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.


Is the issue present in the latest stable version?


If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool and anyone who is building Dolphin on their own can use git bisect.)

[First broken version number here (if applicable)]

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here:

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

What are your PC specifications? (CPU, GPU, Operating System, more)

Windows 10
NVIDIA Geforce GTX 1080
AMD Ryzen 7 1700X

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

Is duplicate of Emulator - Emulator Issues #11717: Frequent JIT cache flushing in some games on AArch64Accepted


#1 Updated by Pikachu025 about 1 year ago

That's most likely JIT cache running out, it's an inherent problem with our current JIT implementation. Not much you can do about that at the moment unless you want to compile your own version with a very large JIT cache (and thus very high memory usage).

Thanks for the clarification, it's not a huge deal but I hope it get fixed someday.

Should be fixed by on x64. I suppose I will leave this issue open since it isn't fixed in the ARM64 JIT.

#4 Updated by JMC4789 6 months ago

It's "Fixed" but not fixed. It's fixed to the capability of our current JIT without a major redesign. But there still will be occasional flushes. I think we should close it or memorialize the issue with a proper "limitations of current JIT" style issue.

Sounds reasonable to me.
