Go in game: as soon as the background appears, the game slow down dramatically. 
The game is supposed to run a 60 FPS!

There is no slowdown for me irregardless of the background. (58-60fps)

I think it is the emu.
Did you try 1964?

Maybe you should test with different audio plugin.
1964Audio(nosync but sounds great) works best for me and I get 58-60fps and 
even during heavy animation/3D, it drops to 48-50s for 1/2 sec(no noticeable 
slowdown of game) for few frames throughout Scarlet cutscene.
Using Zilmar or Jabo will cause slowdown for most part for the same Scarlet 
cutscene.

So, I doubt it is the glide64 plugin or nvidia card but the audio plugin.

The problem with background in this game and few others (e.g. Mystical Ninja) 
is known and explained. When camera rotates, all background textures are 
reloaded each frame, and there are a lot of them here. It seems that NVidia 
cards either can load textures faster or work faster with this texture format. 
Voodoo also slow here. If you have plenty of RAM and VRAM, use GlideHQ texture 
cache. Select 'Store' enhancement mode with large cache size and GlideHQ will 
cache all background textures. Occasionally they all will be cached and 
slowdown will stop.
