Operation Arrowhead performance optimizations/comparisons

[Operation Arrowhead performance optimizations/comparisons]

Hey guys I am one of the senior admin and technical expert from the BAttlegroup XTRA clan (host of the most popular ACE-warfare server). I have been tweaking the OA game to get maximum fps (as got horrible stuttering with the game at first).

There are two factors which need to be looked at;

1) If you have crossfire you will need to enable it as it OA does not have native support for Crossfire (at the moment).

- the two methods are, change the arma2OA.exe to Arma2.exe (but can mean that Arma2OA will startup as Arma2 instead sometimes) or use a program called ATI XFIRE XTENSION (http://forums.bf2s.com/viewtopic.php?id=121774) also found on the bohemia forum.

2) To reduce the stuttering you need to add -cpucount=2/4/6 -exThreads=7 to the start parameters (depending on number of processors as it states on the front page), this has noticable effects due to the OA not being optimised for dual/quad/hexcore processors.

3) The latest 10.6 drivers reduces performance and causes more LOD delays (i am currently using 10.4 drivers which help the LOD)

4) To increase the performance remove post processing (disable) and set memory to medium.

5) Depending on your setup i would recommend to use medium setting with high terrain for a GTX 460 or 5770, up the levels to high for 5850 or GTX 470 and very high for GTX 480 5870 or 5970.

6) for older cards you should still get good performance just make sure you set levels to medium or high not very high, AA has no major effect on the FPS, but allows for crisper graphics.

These are the setting that have been reported by other XTRA members and settings that i have tested. I have also tested on a old PC e8400, 2gb ram, 8800 GTX and with all setting at medium or high i get between 35-45 fps in towns.

My current spec is as follows

Core i7 920 4.4 GHz

6 GB ram (2000 MHz)

2*5870 (900/1250 XFX new bios)

1000w PSU

Custom Water cooling (dual and triple in a cosmos case:)

hey i just did that to my arma2 and arma2 now runs way better than before. i used to get 10-20fps all the time and now its 20-30fps in and out of towns. i did notice a big difference when i rolled back to old nvidia drivers. im using 197.45 and it runs smoother than before.

specs:

amd 64 x2 3.0ghz

9500gt 1gb 197.45 drivers

4gbs of ram

win7 64

settings:

100% 3d res

everything on normal

aa/af/pp all OFF

so far its enjoyable except playing OA. i tried everything for OA but no effect. modified cfg and launch commands and fiddles in my nvidia settings to no effect

lol nothing worked here, i feel left out. mostly everyones confirming fps gains with the launch command entries and cfg modifications and older nvidia drivers, except me. it sux i can only hope for a better patch for OA. in A2 1.07 however, it runs pretty smooth at 20fps. ill stick with a2 for now.

i got an amd64 2.6 x2

4gb of ram

9500gt 1gb

settings all on normal/high

playing on 40inch tv.

jus 20fps with lates nvidia drivers wid win7 64b

[NVIDIA video card(s) owners read here!]

ok i need help.

specs:

amd 64 2.6 x2

4gbs of ram

9500gt 1gb

latest drivers from nvidia and im using win7 64

i purchased a2 and oa through steam and using both current versions, im using dx11. for some reason im getting 10-20fps sometimes even 5-10fps only if im in a town or city. is there a way to speed this up? ive been reading all over the forum about rolling back to 197.45 drivers from nvidia and adding launch commands for both a2 and oa. also turning some settings to off in my nvidia control panel. i pretty much exhausted all options here and im running crysis on high settings and im using my native res for my hdtv 40inch and for some reason thia game hates my pc.
