Cryostasis Nvidia PhysX Performance Patch released

[player1]

One thing I don't get from readme:

Using this patch if you have a high end nVidia Graphics Card and meet or surpass the RECOMMENDED System requirements

Ok, that's big "ATI users stay away" sign.

But then:

Critical Fixes:
o Do Halt by script stack corruption (game crashes in scripts)
o Inability to strafe (or other keyboard settings) with outer controller enabled (wheel, gamepad)
o Shaders 4.0 are working properly on ATi cards now.
o Wires can produce electric sparks, too.

Whaaat?!? So it actually has fixes specific to ATI cards too, as well as some general bug-fixes.

So it's not just Physix Pach?
Is it?

Should ATI users really stay away or not?

Will use of this patch with "advanced physics" turned off (only way "ment to be played" with ATI cards) even more degrade performance on ATI cards compared to unpatched game?

* New weapon available - water gun.
!!! Important! The jet of water from the water gun can be seen only on computers, equipped with nVidia cards with Physics Processing Unit.

If patch is to be used by ATI users (or with physics turned off), does it mean they are forced to have weapons with missing visual effects in the game? Is water gun enabled regardless of physics mode?


P.S.
If patch is not to be used by ATI cards, then when will those general fixes be available to ATI crowd?
