Performance concerns

[Peeling]

I enjoyed the new demo (though it was a tad short) and my only real gripe (apart from finding the hatch astoundingly unresponsive to my mouse movements) was the relatively poor graphical performance. Yes, I know it's doing a lot of clever stuff, but I've just played through Prey at 1440x900 with everything set to maximum without dropping a frame. I've even had the computer-annihilating beast that is Oblivion (with 4096x4096 texture parallax texture patches applied AND the 'action oblivion' mod, which pits me against ten or more highly detailed mobs at a time with full ragdoll physics piling their weapons and slaughtered corpses in mounds around me) running at full frame rate on indoor scenes.

In short, it was a *little* disappointing to see relatively simple scenes chugging a bit in this game. Is there scope for further optimisation, or is that phase of development done and dusted?

Thanks
