When my old PC died i got around to picking up a laptop which i needed for university work and stuff and given i needed high specs simply for the fact a lot of the work is with very high rez image editing and such it didn't cost me much to make sure i could game on here.  Its far better than my old PC and sins runs like a dream in high rez with everything put up.

The only problem is that as soon as i put it in windows mode in vista it slows right down.  I had expected some drop but the game becomes unplayable which is slightly annoying. When i play single player i like to poke about the web or talk to people because lets face it there are some dull bits during the game.  On my old PC which is much lower spec but running on XP windows mode did not slow the game down at all.  Even if i drop this laptop to the old setting i use and turn off the auro UI (or what ever its called) i'm still getting huge slow downs.

Just wondering if there's anything i should/could do to make the game playble in windows mode.
