ArmA and SLI

[Espectro (DayZ) 0]

Hi there

I'm running XP and have 2 GT7600 in my computer. Any other game works with my SLI support, but ArmA doesnt. I have tried renaming my exe to fear.exe and creating a new profile for arma etc. with no luck.

Any ideas?

There was a thread about this some time ago, but it never got an official response. I have two 8800GTX's but I can't use them for SLI because I get better performance with 1 card than with 2.

8800 GTX has known sli issues even with the latest drivers, so this is a different issue, seeing as Espectro is using 7600.

Have you made an SLI profile for Arma or just a profile?

Umm im not sure if this was for crossfire or for sli..

but have you tried renaming ArmA.exe to fear.exe ?

Or you could create a profile for ArmA using the fear profile or something like that...

I havent had any experience with SLI, im just recalling from memory

Gah sorry i really should have read the whole thing

I guess that trick only works for Crossfire.. :S

Jack-UK remembers correctly.

Renaming arma.exe to fear.exe indeed enables SLI. I found that the SLI-profile for FEAR worked the best. But now Nvidia have made a SLI-profile for Arma.

I'm using Forceware 165.01 for XP32 now which have that profile built in.

I grabbed them somewhere in this thread at Guru3d.

Originally they're only for GF88xx-series but plenty of people have modified them to support the 5, 6 and 7 series too.

I'm using a GF7950GX2.

These drivers give me a somewhat lower fps than 93.71+ my homemade SLI-profile, but the rendering is smoother and there is less/shorter pauses when terrain/objects/textures are loaded. So all in all they are alot better. FPS differences are minimal at best anyway (typical was 60 fps is now 55).

Anyone got an imporovement in FPS with x2 8800's now then?

Am i right in saying all the SLI isssues were the nividia drivers NOT BIH's fault?

Nice Tip !!

Now ii can play with my Triple Head in 3840x1024 faster then before with one TFT.

I donßt know whats wrong before but now it runs fine !

Ah forgot:

My RIG: E6600 + 2GB + 7950GX2 and additional running Systembooster for faster Loadings.

Yes, poor SLI-performance is always the drivers. Not sure if there is anything BIS could do at all about that. All they can work on is making the game manage larger VRAM-pools.

The xx10.97.xx drivers were the first to feature a SLI-profile for Arma from Nvidia. But ironicly enough, those drivers didnt detect SLI  

xx11.65.01 even work with nHancer so I might just try to tweak the Arma SLI-profile some to see if I can get a little more fps out of it.

I will report back if I see an improvement.

Any news about your SLI tweakings ?

I have a NIVIDIA 7950GX2 in quad SLI but i'd like to know if it would be safe to install these new drivers or are they only for the 8800 series. At the moment i'm probably only using 1 GPU out of the 4 when i'm playing ArmA because of the unoptimized SLI .
