I would say so far I'm getting really good framerates, I've just got to the "ice level" again, y'know, the bit that really kills ppl's performance, and the lowest I've see so far is about 32-35 fps on average. Its dropped momentarily to the high 20s, but rises again pretty quickly. I tried using 2 x AA, and while some levels were fine giving low to mid 30s, as soon as the action hotted up, they dropped a fair bit and became laggy. I'd rather have the highest fps possible to give me a bit in reserve for when they drop again but remain playable. I'm also using a sort of "mid level" config file, nothing too demanding, but not the smallest as it were. The thing that really surprised me was the performance remaining virtually identical with me cpu at stock. Do we really need to overclock 'em (don't answer that, Iknow what the reply would be

) I'm playing the game in DX9 mode using windoze XP pro, 32 bit atm, I can't see any difference between DX9 and DX10 meself.
If theres any part of the game you'd like to compare performance with, I'll set me pc up to your level, run the game at that point so you can compare notes.
Wrt "warhead" I wonder these optimisations I heard of will be/are?
