I'm glad you are happy with the patch AndroidVageta. Makes me all warm and fuzzy inside. XD

Hell yeah...I mean, just overall, the game is like 1000% better...the Physx really adds a lot to the game play and graphics...Im happy that 1C finally got it right...I still look at them as some greasy mofo's...but what game company hasn't done something horribly bad?

[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?

The only thing the patch fixes for ATI cards is the SM4.0 issue.

Other than that, if you want better Physx performance your ONLY option is to get a new Nvidia graphics card or try to find an old Ageia PPU. ATI could do Physx, but ATI has chosen to not support this like Nvidia has, instead they are going with the Havok physics engine that was developed by Intel.

The Ageia PPU would be your best option as they are PCI and they should be found pretty cheap now a days...I got mine off of Craigslist for a measly $30...and I can confirm from first hand experience that the Ageia PPU is more than enough to handle to Physx inn Cryostasis...and does so quite well at that!

One little problem with that, no biggie though. Havok was bought by Intel, not made by them. Originally they were their own company.

Anyway, just get a PPU, they can be found pretty cheap now. I'd recommend getting a high-end nVidia GPU myself, but if you already have a high-end ATi then you probably will not want to fork out the additional cash.

EDIT: Oh and ATi is also looking into using OpenCL as a physics solution which nVidia is as well.

PS. ATi could not use the existing version of PhysX as it uses CUDA, an nVidia exclusive architecture.

CUDA is not an architecture of the Nvidia card it's just their own API...ATI could run CUDA and Physx if ATI wanted to develop drivers for the cards.

CUDA = Compute Unified Device Architecture

Concerning FPS, my highs are not as high as pre-patch, but so far much smoother and constant (not as many of those horrific drops). That performance article linked to in the other thread helped me achieve better performance as well. I'm running a q6600 at 3.0 and gtx 280 sli and the most recent physx driver released a couple of days ago. Overall, I'm happier but i hope another patch really focuses on performance because two 280s should still be doing better than what it is.

Also, the 360 gamepad lost all support for me; it had partial support before the patch, and now? Xpadder works fine though.
