August 6 2011 Development Update

Hi luthier, you have stated recently that SLI is working but that we are waiting for an Nvidia driver, could you please tell in that case how do you know it is working? What driver are you using and how did you set a profile up to test SLI??

[Cataplasma]

Personally I'm waiting for sli just because my 3D vision setup needs a huge amount of fps. What I see and partially working of cod in 3D is very very cool.
Sli is now partially working (partially unworking) but with the latest patches and drivers a single gtx 470/460 works good with everything full (AA not working) in HD 1920x1080px.

And i hope you get it mate Would be nice to have that and others working.. I'm patient.

Regards

Nvidia dont make SLI work for games, they choose to add profiles in thier drivers, If SLI worked you can easily do this yourself with your Nvidia control panel or by using nHancer. So nothing to do with Nvidia.

I'd be curious what a HardwareMonitoring.hml reveals. You should fire up a MSI afterburner log and post the results.

Well, first of all, there are test builds and versions of the sim that we haven't yet seen. Those patches don't materialize out of thin air. Whether the dev team has a build that works with SLI under optimization (and thus, not yet suitable for release) is anyone's guess and for every negative guess there's a positive one too.

And now for the red text that some apparently can't get enough of...

Quit it with the point scoring. You come up with a valid question (however repetitive) and then figuratively spit in your own bowl of cereal out of spite. After all, if we wanted to keep track of apologies in an impartial manner you'd be one long overdue for claiming Ubisoft was not the publisher.

Generally speaking, expect a thread clean-up pretty soon if this goes on (some baiting and others responding to it)

Tree:


A while ago u asked Luthier "is Sli supported?", Luthier answered: "of course it is, why wouldnt it be" (like asking if headphones is supported hence Luthiers answer)

So far so good, you got the answer to your question.

Now u are wondering why Sli isnt working like it should for everyone (not the same thing as: is Sli supported) and THAT is a question you have to ask NVidia (and AMD/Crossfire). The answer to that is: because none of the company's have made a profile specifically for Cliffs of Dover, simple as that.

It works with global settings but its not working as well as it could, again, because there are no profile specifically for CloD. Its the same with virtually all games until NVidia and AMD see fit to add a profile. It was the same with IL2 Sturmovik. Sli and Crossfire has only become popular in the last few years and there where never a profile from either company that enabled this for IL2 Sturmovik. There where ways to get it to work. i personally had a hell of i time getting my 4870x2 to run even close to its potential simply because AMD felt they had better things to do than add a profile for a 8 year old game that no one outside the flightsim community ever heard of. Same thing now, NVidia and AMD are real guick adding profiles for Battlefield or Call of Duty or Crysis2 (witch took a couple of months iirc, same with DX11 in fact, Crysis was not released in DX11 if u wanna go into that debate to), a flight sim is another matter entirely.

I could be wrong but as far as i know it took RoF until May this year before even adding Sli/Crossfire support.

Read this if you somehow think CloD is the exception: http://simhq.com/forum/ubbthreads.ph...ml#Post3330564 (Btw not a dig of any sort towards RoF, just want to show that supported and working Sli/crossfire is not as given as many seem to think. RoF is just one example)

So the nvidia-created SLI profiles are more than just pre-defined settings that you can already make in the nvidia control panel? I thought that's all the profiles were...

[Baron]

Read this driver readme for ex: http://www.nvidia.com/object/win7-wi...ql-driver.html


For ex. performance boosts for specific card in specific games, those boosts just don't appear out of thin air. Sli and Crossfire implies that 2 or more gpu`s have to work together and not against each other, that doesn't just happen on its own. Not all games work the same way/is coded the same way hence different profiles to get maximum boost. Sli does work with global settings but not as good as it can with a specific profile. (witch in tales more than just pre defined settings made in the control panel)
