007 Nightfire random slowdowns

[kuckilig]

Hey guys,
so I'm playing Nightfire on Dolphin 3.0 atm.
my specs are:
- 3.2GHz athlon amd quad core
- GeForce GT 430
- 4GB Ram

My problem is that I get random slowdowns while playing.
Speed drops from 100% to around 20-50%
and FPS from 60-85 down to 15-35

any way to fix this?

EDIT: I noticed it's mostly when there's people (e.g. enemies) in sight.
