LOL m8 - I'm just installing B&W2 again myself. That's a biatch about the patch isn't it? Thank god I didn't get too far on v1.0.
If the patch doesn't solve your issue, what sound card are you using? Since my X-Fi card has gone in, the only game it has issues with is Command & Conquer Generals : Zero Hour. It had a massive slow-down issue with my old Audigy card, played fine when I switched to onboard audio and then got nailed again with this X-Fi card. Definitely a Creative issue....
