Huge slowdown in build 3404 (64-bit)

[Nerve]

I was using build 3300 which seemed to work ok, but using 3404 made things a lot worse. To put it simply: everything goes 1/2 the speed, maybe even less. I think that the idle skipping feature is broken again, at least in the 64-bit version I'm using, because either on or off it doesn't affect the emulation speed. I'm talking about having the same slowdowns in Brawl and Tales of symphonia, 2 totally different games... Anyone else experiencing these issues? Thanks.
