Crossfire/SLI or dual GPU Card Arrowhead Issue (4870x2, 5970 etc).
The thread comparing performance of the game between Arma2 and Arrowhead seems to be swamped with discussion about the performance issue with Arrowhead and more than one GPU.
I'v seen a few posters with 2 GPU's describing that Arma2 is running great but Arrowhead is stuttering and dropping frame rate. The renaming of the Arrowhead .exe and V-sync disabling etc have been attempted unamously without improvement. Can BIS provide any support/encouragement? Anyone else with this issue please also post.
Would be nice with some official feedback, though I'd like to add the problem also seems to be very closely tied in with the Core i7 users, as 90% of the users having major stuttering and micro-freeze problems have a CPU in this class.
Do we really have to go back to square one, performance wise every time?
Same here I7 920 @3.8 and sli 480 gtx's have average framerate in that bench normally around 55 ish all at mostly very high settings, i renamed my exe to arma2 which helped with the cards utilization percentages but thiers a hickup with this ever so often frame drop and stuttering.
Just to update i set my render frames ahead from 3 to 0 and that actually seemed to smooth things out alittle, still needs work though awesome game, love how they have elcans on the scars love that sight although they need to have the switchable magnification on it like in real life. mk-17 scar is the bomb
Run the patch with the vanilla file names for the arma2.exe and arma2OA.exe files to have it install ok. I also changed my arma2.exe file name to arma1.exe and arma2OA to arma2.exe, after the update, as per previous advice about driver recognition.
Not sure which of the above helped, but it's certainly running better on the very high settings with AA disabled or low with a 5970. High AA setting reverts the game to low frame rates again. I suspect it was the patch update rather than the driver rollback that helped. But I'll try some combinations another time.
Where do i set the "render frames ahead" on the ATI 5970 ?
I can't find it anywhere in the CCC.
Anyway, i did some testing, and found slightly interesting fact:
I ran the benchmark mission 10 times with 75Hz refreshrate, and then again 10 times with 60Hz refreshrate, and i got smoother game (higher minimum FPS) with 60Hz refresh rate instead of 75Hz.
The difference is very little, but maybe for some of you the difference between various refresh rates can be more significant - maybe its worth a try.
Settings i used for the test: Spoiler:
Texture detail: Very high
Video memory: Default
Anisotropic filtering: Very high
Both resolutions: 1280x1024
Terrain detail: Normal
Objects detail: High
Shadow detail: Very high
Postprocess effects: Disabled
My HW config: Spoiler:
Intel Core i5-750 @2.67GHz
ATI HD 5970
Windows 7 64bit
I downloaded ATI Catalyst™ 10.6 Profiles Update and renamed "arma2OA.exe" to "arma2.exe",
and from now on i can see the "ATI Crossfire X" logo when i run it as "arma2.exe".
BUT, there was only very slight imporvement in FPS.
I ran another 10 benchmarks (same settings as last time) with these results:
47, 47, 45, 47, 48, 46, 49, 44, 49, 45 => avg. 46.7 FPS; min. 44 FPS
So, maybe the game EXE needs to be specially optimized, AND/OR my processor is too weak (Intel Core i5-750).
Anyway - if your game wont run in Crossfire, make sure you downloaded and installed the last profiles (and also rename/copy the game EXE).
Hello, I finish proving my copy of arrowhead, and I am with the surprise that runs bad, it does not run well as it arma 2. runs to pulls, is not possible to be played, the game feels heavy and fps raises and lowers without knowing so that: S.
Arma 2 it game to full without problems, even recording with fraps, and now with patch 1,07, the game practically is a pen as it runs, but I cannot say the same of OA: (
i7 920 2.66ghz
crossfire xfx ati 4890
6 gb ram 1600 mhz
win7 64 bits.
drivers catalyst 10.4
OA VERSION 1.52
Similar issues with both games: Arma2 runs badly with both cards, lots of stutter etc, but with one card it's massively improved. I get 60 FPS on the benchmark regardless of whether I have one or two cards active.
With OA, running two cards I get FPS of 28ish on the benchmark and truly terrible performance, even on normal settings (stuttering, poor draw, texture pop in etc). With one card, FPS increases to high 50's on benchmark and runs like a dream.
O'clocked Core i5's at 3.7gig (ish), 2 x Radeon 5770, 4gig Corsair DDR3. ATI Cat drivers @ 10.4
Don't get this issue in any other game, would be nice if OA could utilise multiple GPU's successfully... but is this only an issue with ATI cards? Btw OA is Steam version, but A2 is on-disc.
Anyone had any joy with the 1.52 - 1.52 hotfix idea?

Just turned my mipmap detail level in ATI cataylst software from high quality to performance and its working a treat at very high settings on a single player mission. 45-60fps on the Hike in the Hills Mission with smooth game play as in arma2.
So, not isolated which the 'fix' for me was out of;
1. Updating from sprocket version 1.52 to 1.52.71816. (With the original names for armed assault 2 and operation arrowhead as the .exe files - see no. 3).
