Apparently, even in 1.0, PhysX effects are always turned on for ATI cards (leading to poor performance due to use of software mode) regardless of Hardware Physics settings in Video menu. You can see this clearly on 6th level, when you enter the room with frozen body chained over the hole. In that place, when I put all graphic settings to minimum (800x600, low, all off), I get 12fps. Outside that room it is over 60fps. With all settings at max I get 10fps in that room (1280x1024, high, all on). It's clearly software use of PhysX that can give such slowdown.

Anyway, Mirror's Edge did this better. It properly disabled all PhysX effects (either by removing them, or replacing them with simple effects), when hardware physics option is turned off. Leading to playable game on ATI cards.

.

Anyway, what baffles me is that in patch readme there are clearly some bugfixes too, not just PhysX improvements. There is even that fix for 4.0 shaders and ATI cards (when colors get garbled when gamma is above 1.0).

But then, readme says you only should use it for high end Nvidia cards?

And what about others who just want bug-fixes?
Very confusing...

I understand that turning on advanced PhysX effects from 1.1 patch on ATI card would lead to unplayable game. But when disabled, can this be used just like any patch, to fix bugs, even on ATI cards. And what will happen with water gun? Will it be disabled, with advanced PhysX turned off, or will it still be present, but fire invisible water.

I know from my point of view they fixed a really annoying error that would throw me to the desktop with a visual c++ runtime error every time I tried to load up a new map. I did see some performance improvement, but I think my 8800GT is just not up to running this game at a good frame rate.
