im not getting to bad sli performance 1600/900 all high no trees

any update on this?

I'm still only getting 40 fps in Hurricanes V He111 scenario, whether I turn on or off SLI in NVidia control panel ?? 2 x 580

I refuse to use Nvidia Inspector as it's full of SPAM software.

I have the latest Dvidia drivers 3.04 or something like that

I cannot find any game setup section in Nvidia Control Panel, other than in 3D section ??

Help!

.

Sorry He111,

There has been no further development with Sli from the team as yet so far as I can find out, BlackSix seems to be avoiding the questions that I have put to him. Lutier stated back in April 2011 that Sli would be their next big priority, this is a quote from him about 17 months ago: -

5. Resurrecting SLI support. This is our next biggest priority; it’s done by the same programmer now in final stages of optimizing buildings. We are really hoping this will be a quick task, but I don’t have an ETA at this point. It’ll either be a couple of days, or a much longer undetermined amount of time if we have to submit versions to card manufacturers and ask for their input.

The delay may be because of trouble they are having getting the graphics engine to perfom as they want, but no one wants to talk about it it seems.

I use Nvidia Inspector and have not found any spam software that you mention. My Sli system as you will see from my sig is far below your system but I'm getting good frame rates with it (nearly double that of one of my cards running with Sli turned off). I am only an off line player so can't comment for online performance. Try single player mission, London Attack and let me know what fps you are getting, with your 580's you should have fps at least 80fps with Sli with High settings on. You can make your own settings with control panel pointing it to the C.o.D exe file. I continue to try different things to see if I can improve the performance (especially the micro stutters that I'm getting but I even have those running just one card so can't put it down to Sli as some would suggest). Certainly the sim is very playable for me, try Nvidia Inspector along with EVGA Precision Tool. What are your system specs?.

Edit: - Opps sorry just noticed your sig with specs, I see that your m/b is 2x 16 pci-e similar to mine except my m/b is Amd. Check and make sure you have the Sli link seated correctly, if it isn't you won't get Sli performance. Are both the cards running at the same temps and usage?(within 2--5 deg temp and 5% usage, the peak usage will change from one card to the other depending on demand). If you have one of your cards running on idle there is something wrong with the setup.

Hi KeBraNto,

Sorry I haven't replied earlier, I have just sean your post and have tried the Dynamic tiling "on". Haven't had a chance to give it a good try as yet, maybe a slight rise in fps but still have micro stutters (don't notice them that much unless I'm looking down towards the ground chasing a target, certainly nothing during high altitude combat).

When playing Single Mission - LondonAttack i get 30-40 fps

I run the game at ultra graphics - Vsync on, Anti-alias off (BTW, how do you turn the trees off ????)

I think i should get better with 2 x 580s.

Will do further testing ...

He111,

I have all my video settings on high except for forrests and buildings which are on medium. Vert/ sync off, grass off, shadows off (this is a big fps hit). I'm getting the same fps asyou where there is a lot of flack etc but prior to and after that fps 50--70.min sometimes as high as 90. There must be a lot of difference in our video settings otherwise you should have better frame rates than what you are getting. The trees should be controlled with the forrests setting (there is an off selection there).

yeah, ok after quite a bit of testing, I agree with most of your findings except SLI (turning off / on SLI gives no difference to me)

Current released version of CLOD I get 25-30 fps with everything on max.

Beta 18956 version of CLOD I get ;

* everything on Max - 30-40 fps

* Med forrest / housing - 40 -50 fps

* shadows turned off - 50 -60 fps

* no forrests - 60 fps

SLI turned ON or OFF - same

Obviously SLI is not working for me running AttackLondon .. maybe it only kicks in at different loads, not tested in AttackLondon ???

I've tested SLI on my computer, it is running playing Shogun Total War.

He111,

Here's a recent screen shot from my system showing EVGA Precision Tools readout in the r/h top corner. you will see that my 1gb cards are running at near max V/ram, card temps are very close to being the same (the Asus card has always run a few deg cooler than the EVGA) the % of use is near the same with both cards and they are running the same clocks. The % of use does vary between the two cards depending on which card is carrying most of the graphics at the time but they are always within 5% of each other. Check and see if your cards usage are about even when running C.o.D. if they aren't your Sli isn't working. What will show is one card or the other is maybe using only about 10% while the other maybe using about 80% and the temp of the card using about 10% will be down also. Are you using EVGA Precision tool or similar? MSI also has a tool that does a similar thing and these are free downloads from the respective sites and are compatibile with all Nvidia based cards. I couldn't balance my cards succesfully without this tool as they came with different clock speeds and voltages. I know you have said that you don't want to use Nvidia Inspector because of spam but I have never had spam with that software.

I've uploaded another screen shot taken with Sli disabled, as you will see Card 1 is now running near max card 2 is idling. FPS are down also

ok, i used Gadget GPU meters on both cards. When playing Totalwar, both GPU gadgets showed both cards in action but when playing CLOD, only one gadget showed signs of life.

Gadgets may not be the best tools but they do show temp, gpu useage, gpu mem useage etc.

i'll wait and hope the team can look into SLI soon.

Graphics Bug on Replay
 

Please, I need some help here: on replay the engine acts as if the fuel pump has gone out and it revs up and slows down and sometimes cuts out with the prop stalled. There are other minor details presenting problems but this engine issue is the one that most bothers me. Thank you so much.
