What's the problem? Describe what went wrong.

EFB2RAM accuracy was increased with build 5.0-3322. This has caused a noticeable performance drop in Paper Mario: TTYD at high IR.

What steps will reproduce the problem?

Switching to skinny paper mario (Hold R button) will cause a less than 100% VPS framerate on my system. Prior to Build 5.0-3322 this caused no slowdown.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

5.0-3319 - No slowdown
5.0-3322 - Performance drop

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

PC Windows 10, Nvidia GTX 970, Core i5 4590
Running 2.5x native res, 2x MSAA, Community texture pack

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

Save file (first file). Exit east from save point, switch to skinny mario (Hold R button). Performance drops.

I assume this is fine and not a regression/bug per se, but just wanted to track/note the performance loss for future reference.
