What's the problem? Describe what went wrong.

The videos in the game run very slowly in single core mode. 1 FPS at 100% on the VPS. The game runs full speed in dual core mode.
The long videos when starting the game are not skippable.
When it eventually does get in-game the gameplay runs at full speed.

What steps will reproduce the problem?

Boot the game.
After the Safety Screen all videos in the game will run at at 1 FPS.

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, 5.0-15729

Is the issue present in the latest stable version?

Yes, 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.)

The master branch 3.5-608 ran full speed on single core.
The FIFO-BP branch introduced this issue in 3.5-644 on single core.

FIFO-BP-3.5-433 and previous run at full speed on single core.
FIFO-BP-3.5-434 and all builds since runs slow on single core.

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)

i7-8750H
GTX 1060
Windows 10
8GB DDR4

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

Let me know, I'll see what else I can do.

Can you try an extreme GPU underclock to make up for our shitty GPU timings?
