Resistance: Fall of Man [BCES00001]

Hey guys,

Do any of you have any recommended settings for the emulator for this game for me? I am running it at 720p 30fps on the EU copy and notice whenever there are many enemies alive near me my emulation slows to a crawl and the audio starts cutting in and out. It's fine for moderate to small number of enemies and indoors it's perfectly fine.

My specs are:

I7-6700HQ
970m
16gb ram
Win 10

Any settings or tips that will help the performance on these specs would be greatly appreciated!
