Dolphin slow on good pc

[Doodle]

So most hard to run Wii games lag at some points, but Super Mario Galaxy runs the worst. In most places in the game, the game runs at 60 fps, but it really lags in some places, especially beside or above the bedroom at certain camera angles were the game will run at only 35 fps. Here's my PC specs: Nvidia GTX 960 4GB, AMD FX 6300 3.5 GHz, Kingston 8GB ram, Windows 10 x64, and Dolphin 5.0-9156 x64. I've tried changing the power plan to high performance and changing the Global and dolphin NVIDIA control panel power setting to prefer maximum performance, updated my Nvidia graphics drivers and tested each graphics backed [Vulcan runs the best] and updated my Vulcan runtime libraries but those didn't work. Turning on Skip EFB Access from CPU fixes the lag, but then i can't pick up star bits using the Wii pointer. I am also using the Mayflash DolphinBar.
