Dumb question because I edited out an even dumber question as I didn't read the main post correctly: Does Physx acceleration help improve gameplay at all in terms of how physics preforms in your game? I mean will your car bounce around as much, etc in terms of physics? What about if you spawn 144 cars on each side and bombed them - that would seem like a situation in which physics acceleration would come into play. Now if you talk about a situation like that and its impracticality, well... you don't know me and the editor

I have to admit the point made above about Operation Flashpoint Dragon Rising... its only about 2 or 3 months away and if it runs fast, has similar features to ARMA2... I think it will take many people away.

No. Physx acceleration if I remember correctly is something that the game has to be coded to support, and even today I think only a handful of games are supporting it (granted a bigger handful than before Nvidia bought the PhysX tech from Aegia), and since ArmA2's physics engine is not that much different from ArmA1, I doubt you'll find any increase in performance for what physics the game does have.

If you bombed 144 cars, most of them would explode nearly identical with limited movement. No big flashy 2 ton spinning pieces of metal flying about, tumbling all over the place like you'd see in more physic heavy games like Crysis or CellFactor: Combat Training (Cellfactor had full PhysX support, and is quite spectacular to watch).

Alright cool. Also, I dont have a physx control panel like Dwarden talks about... What then? I went to Nvidia's website and looked up the Drivers for PhysX and went to install them but my PC said I have them installed and it asks to uninstall. I uninstalled and reinstalled.

Any idea how to get that menu so I can complete this process fully?

If you have an nVidia card from 8000, 9000 or 200 series, then all you have to do is download the latest GRAPHICS driver from nVidia. The physX drivers are included in the video-driver, so you don't have to do anything.
In the control panel from nVidia you will see a tab where you can enable or disable physX. But it is enabled by default, so no worries there.

I've checked latest beta drivers without any fps change.
Hover strange is, that on my config results don't depend on resolution nor fssa/aa.

I have tested with scene in the forest and get 19-21 fps for both drivers (most settings on normal, postprocessing disabled). When I changed resolution from 1920x1280 to 1600x1024 - nothing changed with fps. Postprocessing low eats about 5-7fps.

So.. My idea is, that bootleneck is the cpu. May C2D 6400@ 2.7GHz be too weak?

my config:
C2D 6400 OC 2.7GHz
Asus P5KC, 4GB DDR2/900 MHz
8800 320 GTS OC 600/950

are you using FRAPS? it doesn't work with ARMA if you are.. at least not for many here. some people think it might be counting the patched screen overlay for the Steam version.. which might explain why all of us with steam seem to get 21fps back regardless of settings.

just a thought.

What a load of missinformed nonsense. It works perfectly fine with both Arma 1 and 2.

What you are referring to would be using FRAPS to record video at the highest settings which does have an effect on FPS. Using FRAPS as a screen overlay to show FPS in game has no discernable impact on the game.

No. Physx acceleration does NOTHING for Frame rate, i checked with FRAPS.

I bought arma 2 from steam and im having a stutter problem at the main menu and in the game. Some times its so bad i cant even start the game up. Im getting 30-60 FPS for 2 min than it drops lower than 10 and just locks up and keeps doing it. Not playable for me right now. I have the latest patch. I also have 4gb ram but i guess this only says 2gb bc i have win vista 32bit. i would really like for people to give advice
