COD4 Requires DX9 - MBP SR Supports DX10. Update?

[Spliff]

I just bought COD4 and am planning on installing this on my MBP (with BootCamp of course), however the requirement is to use DX9. Since SR MBPs 8600M supports DX10, should I just update Windows to run on DX10 or will this have an adverse affect on the game?

I am sure DX10 is backwards compatible for DX9 games, but is this optimal for COD4 since this is my first (and only) PC game on a Mac?

The vid card will run DX9 too. I'm playing just fine on my MBP with XP SP2.

Stick with playing the game in DirectX 9.

If your running Windows XP this is a non-issue really. DX10 is only available in Windows Vista. The game will run using DX9 what ever you do though (DX10 is backwards compatible).
