Hi folks,

 

I know there are plenty of performance threads out there. I have read through many of them. I know the game runs like garbage for a majority of people regardless of how beefy their computer is. And I have seen a couple of Crossfire threads here and on various forums, but nothing recently. I want to start a thread for performance issues and optimization for AMD Crossfire users with the new OMEGA drivers.

 

I have been able to get DayZ running okay using one of my cards on mostly low settings. However, I cannot seem to get the game to run well with crossfire at all. Here are some of my issues:

 

• Cannot run the game above anything but lower settings. Seems like crossfire doesn't do much besides split the load between the cards. Each card never runs above 60% or so, the the game chugs alone anywhere near a building. Does anyone know if the performance issues near buildings are VRAM related? or just poorly optimized rendering?
• Weird flashing problem in crossfire mode. The screen will flicker with a white strobe-like effect and then the whole thing goes bright white for a second and then quickly dims down to normalcy. This happens kind of randomly and then after a while of playing sometimes it start happening a lot, so much that it's kind of unplayable and really bad if in a high pop server.
• Tried running the game is 1x1 optimized mode and I get this weird delay issue. Almost like there is heavy mouse acceleration on. I guess this might be some kind of input lag? Strangely, this mode renders the game the best out of all of them, but the mouse movement is too sluggish to be playable.
• Tried both AFR friendly and tried using the ARMA 2 Crossfire profile. Neither of these seem to improve performance much, if at all. In fact, I almost think one card runs the game better at similar settings.
• Game generally runs like poop.

Some things I have tried:

 

• Turned off post processing, AA, edge smoothing
• Changed shadows and water to low
• Turned off motion blur, and greatly reduced bloom
• Changed textures and texture filtering to high (No reason I can see this would cause a problem with 2GB VRAM)
• Changed VRAM usage from auto to 2048MB (Does this really do anything?)
• Turned off alpha to coverage
• Tried running the game using the ARMA 2 crossfire profile, and all the other AMD Crossfire modes
• Set everything to low and turned down the resolution (This helps a lot, obviously. But a 5 year old laptop should be able to run these settings at 60FPS)
• Tried running AA from the AMD Catalyst software instead of in-game
• Tried frame buffering on and off
• Tried turning off surface format optimization and texture filtering.

Basically, turning all the options off or low is the only thing that makes the game run acceptable in an area with more than a few buildings. It's worth noting that The game runs REALLY well in the forest with one card, even with higher settings. The buildings really destroy the performance.

 

I would appreciate anyone who can give me their settings who also use Crossfire in a similar setup. Also, if anyone has specific .ini changes for a crossfire specific setup.

 

Thanks a lot!

strange, my old rig which was crossfired 5770's the only problem I had was every so often it looked like I had been flashbanged in slow motion, mainly in the trees (possibly something to do with the sunlight coming through trees?) they always performed ok other than that though

Your gpus are only reaching 60% load because the cpu can't pass enough information through to feed them half the time,  as DayZ is very heavy on the cpu.  Alot of settings when set to low actually offload to the cpu instead of the gpu and cause the bottleneck to be even worse. If you can't shut it off completely set it to normal or high and then mess with your object count until you see your gpu load actually start to go up.  This is true for arma 3 as well, you can sit at the settings screen and mess with object count and once you raise it to a certian point the gpu load actually starts to drop instead of raise as your cpu is no longer able to keep up passing info to the cards.  As for your crossfire specific issues (if there are any) I can't help you there I have nvidia sli.

Thnaks for you input. That is interesting.. I guess I am at a loss as to how my CPU can't handle it if what you say is true. My processor overclocked to 4Ghz can handle quite a bit. I've never come across any game that was bottle-necked by my CPU. And the PCI Exp 3.0 bus is in no way limited by any modern game. It's capable of pushing lots and lots of bandwidth. Anyways, how do I mess with "object count?" There is only the option for Object detail. Is this an .ini tweak? Thanks.

Optimism is not perfect currently for DayZ, but after the new engine, and renderer and such is added into the game, they will work on optimization. Until then I hope that you can get DayZ running smoothly! It's an amazing game it can only be truly played, when at the highest settings! ;) No, but seriously though, I hope you get it running!

xFIRE has never worked in bis games. 

 

I had to but three 7970's to figure that out

Something about using a ArmA2/CO profile, not an expert but I have seen this often.

I have same problem dude. 

 

System specs:

Intel Core i5 467K (overclocked to 4.4 Ghz)

16GB DDR3 2400Mhz  

2x MSI Radeon HD 7970 Twin Frozr III 

 

I use the ArmA2/CO profile. Game runs well in woods but like most peeps game really struggles in cities. In order to get payable fps in cities im forced to changing my Object settings from high to very low and disable Anti-Aliasing. Hopefully new render brings better optimization.
