New super smash bros fps drop (ice stage) 1-2

[shoober420]

Hello,
I am experiencing some problems on the ice level and various other levels. Some stages run perfect (60 fps) and some stagger down to 30 fps. i use EFB texture mode and have the r6882 revision. Either the stage runs perfect or it will drop down to 30 fps. Ive tried everything i can think of from switching settings, switching plugins, and disabling sound. ogl and d3d have the same problem. Can somene help meh?
