What's the problem? Describe what went wrong.

With the debug AR code enabled, the game runs exceedingly slow (35-37fps) regardless of video backend. This slowdown didn't happen on earlier Dolphin versions, nor does it lag console to my knowledge.

What steps will reproduce the problem?

Add the following Action Replay code to GM2E8P:

185BC473 00000003
005BC473 00000003```
Launch the game and enter the debug menu (Test Mode in the ascii menu over the title screen, or press Start within userland menus). Framerate should hover around 35-37fps.

**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, this lag occurs on 5.0-15255

**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.)

First broken version is 5.0-14581

**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: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer**

N/A, not a graphics-related issue

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

Windows 10 21H1
Intel Core i7-10750H CPU, 2.6GHz
NVidia GeForce GTX 1660 Ti GPU

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

Logs, config, and saves were identical across all versions tested.
