Severe lag issues with only one game

[BikerBones]

Okay, so I searched the forums for topics about this game (Namco Museum 2001), and I only found one. One user mentioned having the same problem as me, but they didn't mention finding a solution to it. Google has been unhelpful, so now I'm here. A decent chunk of the games within the collection lag horribly, like to the point of being unplayable. Especially the Arrangement remasters. I've enabled dual core, reduced graphical settings to the minimum, checked to see if maybe there are some settings on my PC that are supposed to be enabled for Dolphin that aren't, and toggled just about every setting to every possible configuration and I've come up short. This is the only game that gives me trouble on Dolphin, and apparently either nobody else has had this issue, or nobody's cared enough to document it and the solution. So if anyone happens to have had experience with this issue, and found their own solution, please let me know!
