[BUG]Low frames/Slow loading

[insidious]

Bought the game and fired it up to see insanely slow load times, a whopping 10fps in menu/docked, and 0.9fps wile playing.
I've tried the workarounds i seen on the forums but nothing is working "these were mainly intended for ATI users"
As for the loading it took nearly a half minute to load into the main menu.

i7 870 oced, EVGA P55LE mobo, EVGA Geforce 570GTX oced, 8gb Gskill pc3 2000 oced, 2x WD Cavier 500gb sata3 raid0
All drivers up to date. On steam if that helps..
*EDIT* would help if i added my os haha "Win7 pro"

Found a possible workaround for this. the low frames were occurring in window mode but when i set the game to full screen /w black borders frame rate skyrocketed into the 80s+. Load times were unchanged.

Same problem/workaround here.

My FPS in windowed mode is absolutely ridiculous, loading times too.
On fullscreen mode the game goes fast as lightning.

Definitely a bug, unfortunately :/
