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 ! > "OK"

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

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

Spoiler:

---

2a.
NVIDIA SLI owners shall try use NVIDIA beta SLI profile ARMA 2 support for 186.18:
http://www.nvidia.co.uk/object/nvidi..._patch_uk.html
Anyone who install nVidia's fix should deinstall/remove the EVGA fix before installing nVidia's, if its previously installed!

2b.
NVIDIA SLI owners may gain additional performance when using EVGA SLI enhancer

http://www.evga.com/articles/00463/Default.asp

more info and feedback about EVGA SLI enhancer here: http://forums.bistudio.com/showthread.php?t=76369

3.
VISTA (64b) users may get way faster/smoother framerate in windowed mode with 186.18 drivers
*windowed mode is now available by just selecting ARMA 2 in STEAM client gameslist and right mouse button clicking on it and choose Launch in windowed mode

4a.
force VSYNC off in drivers

4b.
Alter RenderFramesAhead in ARMA2.cfg


---

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


NOTE:

on some OS (e.g. Vista64) with 4+> GB there is need to startup game with -winxp commandline paramater
(STEAM games list>right mouse button on ARMA 2 > Properties > Set Launch Options)
or/and limit windows memory in startup paramaters to <4GB memory
this vary by driver builds / other system variables, please try first the commandline option

fixes and improvements are in work ...

thanks dwarden!

No thanks from me:

Asus A8N32-SLI
Toledo 939 4200X2 @266*11=2933Mhz STOCK VOLTAGE
EVGA 8800GTX @621/1566/1900Mhz STOCK COOLER (with 186.08 but tried also 182.50)
2GB of DDR1@SYNC 266Mhz 3-3-3-8 @2,75V or 4GB of DDR1@ASYNC 210Mhz 2,5-3-3-7 @2,8V
SATAII RAID0
Vista64 SP2

In-game bench (1680*1050 low details):
PhysX ON: 22 FPS
PhysX OFF: 22 FPS

So bad.

No changes in FPS for me.

driver: 186.18

I have just read update... but what if 4GB RAM (so no more than 4GB)... do we have too to limit the amount used by O.S.?

[Dwarden]

punisher that fix is mainly to these who got that ugly 'no textures' corruption caused by incorrect VRAM values returned for detection

[b101uk]

the demo runs ok with PhysX ON for me

will try turning it off later just to see!

win XP pro SP3 (32bit with PAE)
i7 920
gigabyte EX58-UD4
6gb DDR3 (3 * 2gb)

GTX260 (Device ID = 05e2)

drivers: 186.18 WHQL xp32 or 190.15 beta xp32

PhysX: PhysX_9.09.0428

Probably your cpu that's the problem. The game really likes a powerful cpu more than anything.

Yeah it could be.

appreciate the effort Dwarden but this made no difference for me, none of them.

8800GTX 768
AMDX264 6000+ @3.1ghz
Vista X64
186.18

it seems no matter what i do apart from the post effect detail i hover around 20fps. even if i drop the render resolution - no change.

it's as if it is capped at 20fps which is obviously absurd and not what's going on - but i have no other way to explain it. it's as if all settings apart from post process have NO effect on my FPS (always 20-22 in the area I test) then with post-process cranked I lose about 5-7 fps.

i am sincerely baffled. i should be able to run this with a super low resolution and all settings on low with more than 20fps - but i get ZERO increase in going from all settings on very high (post process disabled) to all setting LOW and render window at lowest settings.

something strange is going on.... that's for sure.

-just tried the -winxp, no change.

[Baleur]

No change.

punisher, do you have the same framerate when you drop the render resolution as well? just curious because we have a similar setup.

try dropping it to the lowest render resolution possible and let me know if you still get 22fps (which is my average as well).

if you're getting the same thing then something is definitely wrong here. we should see marked improvements in framerates when dropping our resolution.

Similar hardware configuration to mine you have and same problem. Yours has a faster CPU\RAM too and no changes.

The game is definetely the problem.

Yeah mate, already tried @ 1024*768 with 50% render resolution and what I got was just 24-26FPS! (with all the rest on MINIMUM)!


(We had same ideas too lol)
