What's the problem? Describe what went wrong.

After upgrading from build 8876 to 8878, Dolphin emulation is very slow. Even on lowest settings, I got 1-2 fps, even on GameCube/Wii main menu.

What steps will reproduce the problem?

Upgrade to 8878 and start any game, with any setting selected.

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

Yes, 8878

Is the issue present in the latest stable version?

No, 5.0

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 https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

5.0-8878

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

  • CPU: Intel Core i7-5700HQ @ 2.70 GHz (3.50 GHz)
  • GPU: Intel HD Graphics 5600 + nVidia GeForce GTX 970M
  • OS: Windows 10 Professional (Insider) Build 17763.55

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

N/A, but tell me if you want anything more...

Same thing here on two different PCs: super slow motion (1-2 fps) with every game (GC and Wii); strange that no one noticed that before merging

Yep, I confirm problem is gone by my side after reverting the change (build 8882). I'm curious about what went wrong there...

From IRC:

(18:09:30) delroth: Zexaron: my guess is that the bug was inhibiting writes to HID0.ICE
(18:09:34) delroth: and so no instruction cache anymore :)
