What's the problem? Describe what went wrong.

The game causes Dolphin to chew through RAM at a ridiculous rate: Less than a minute in and it gobbles up 5GB of my 8GB of RAM, grinding my PC to a screeching halt.

What steps will reproduce the problem?

  1. Launch Dolphin
  2. Launch Super Smash Bros. (preferably with Task Manager already open)
  3. Observe RAM usage skyrocketing

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

The issue persists as of 5.0-7263.

Is the issue present in the latest stable version?

No, this is not a problem in 5.0 stable.

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 seems to be 5.0-5757, though I'm not sure that makes sense.

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

[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)

CPU: Intel Core i7-4770k@4.4 Ghz
GPU: NVIDIA GeForce GTX 970 w/ 4GB VRAM
OS: Windows 10

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

[Anything else here]

I think staying at 1x IR prevents this from happening? We're caching a lot of stuff with this game - this issue has popped up before.

Yeah. On closer inspection, EFB2RAM works around the issue, confirming this as a reoccurrence of issue 8450.
