-1. DISABLE AMBIENT OCCLUSION in NVIDIA Driver Control panel !

0.
You shall try first NVIDIA 195.xx beta drivers or later ! Up to 12% performance increase in ARMA 2

1.
NVIDIA videocard owners with newer cards and drivers supporting PhysX when disabling PhysX acceleration:
* this works mainly for 260 and newer GPU serie resulting into performance boost for NVIDIA users in ARMA 2 , yet some 9800/8800 users experiencing smoother gameplay


A. Control Panels > NVIDIA PhysX control panel > Settings > switch to NO PHysx acceleration ! > click on "OK"

B. Right click on desktop > NVIDIA Control Panel > Set Physx configuration > Select "Disabled" > Click on "Apply"

2. SLI profile should be part of latest drivers ,
so following applies for old drivers only

2a.
NVIDIA SLI owners shall try use NVIDIA beta SLI profile ARMA 2 support for 186.18:

Anyone who install nVidia's fix should deinstall/remove the EVGA fix before installing nVidia's, if its previously installed!

2b.
NVIDIA SLI owners can gain additional performance by using EVGA SLI enhancer

3.
VISTA (64b) users may get way faster/smoother framerate in windowed mode with 186.18 drivers

4a.
force VSYNC off in drivers

4b.
Alter RenderFramesAhead in ARMA2.cfg

5.
Try turn off Threaded Optimization in the nVidia control panel to resolve
crashes with "V-buffer creation error" & "Vertex Buffer out of memory" etc.

please when posting feedback into this thread add what driver version of PhysX and NVIDIA (both are standalone packages) You have

Spoiler:

on some OS (e.g. Vista64) with 4+> GB there is need to startup game with -winxp commandline paramater (arma2.exe -winxp)
or/and limit windows memory in startup paramaters to <4GB memory
this vary by driver builds and other system variables so please try first the commandline option
fixes and improvements are in work ...

Thanks for the update.

Hope it helps....!

Yes, I can confirm that it works. I have a single nVIDIA GeForce GTX 280 and I tried disabling it in the nVIDIA Control Panel. Worked like a charm. My FPS increased by about 10 to 20 FPS.

Turn PhysX off? For real?

:O

I'm in for a try though, so thanks..
Also DLed the SLI enhancement, will try that later too.

thanks again

***EDIT***
Have now DLed the SLI enhancement. This made Nvidea control panel recognize the ARMA2.exe (which i renamed again from Crysis64.exe to Arma2.exe). With standard settings I started playing, which seems to work very good for me.
have yet to try SLI settings + turn PhysX off

***EDIT***
Have now tried using SLI ---> works great (about 36-38 fps)
With physX off I find video goes a little bit less though.

Still keep crashing, though not so much anymore (in MP). When I do get an answer about the origin of error, it's always nvidea..... So hopefully THEY will provide new driver (newer than 186.xx) soon
