XP is only Direct X 9 which is definantly no good for any of the latest games.
Like you said, I also get CTD often with XP. My settings are the same as yours except I have Land shading on low. (Is it worth being on high?)
I seem to get relatively the same FPS on average as you too.
So does CoD support Direct X11 or not?
Because my Video card aswell as Windows 7 support it...
Thanks for your reply.
