Hi All!
Installed XP on my 2.0 Ghz MBP last night using Boot Camp, followed closely by Battlefield 2
After running the patches for BF2 it worked a lot better than expected, in fact after pumping the settings up to High across the board it still performed way beyond expectations. I've not tested the fps yet but it plays a lot better than the 3.2 Ghz Intel based PC I have been playing it on.
I have a movie of the gameplay but nowhere to put it yet, I'll come back when I find a place to put it.
