Luthier-Will SLI be fixed in the patch?

However, two GTX 580's SLI beat a 590 by 15-20%. It actually has a tough time beating 2 GTX 570's. I believe the GTX 590 is underclocked at about the same as a GTX 480 for heat issues, which is why it is so quiet.

Working SLI in CoD would make a fair difference to the 590 because you cannot turn off SLI.

The last word from Luthier on SLI was that Nvidia's next driver release would have a profile for CLOD in it, there have been at least 5 driver release since with no mention of CLOD. Luthier's track record with SLI is somewhat shady, I asked in 2009 if CLOD would support SLI, after many avoided posts Luthier finally answered and said ;why wouldn't it work' he then went on to say that he would talk no more about SLI.

Then on release he blamed the 'Epilepsy filter' for killing SLI, but when it was removed SLI still didn't work.... strange that. Since then Luthier claims that SLI as been fixed but now it's Nvidia's fault for not releasing a driver to support it. We know that Luthier would never tell us any pork pies he has stressed this on many occasions, so I guess he's just been unlucky with this particular problem in that other comapanies like Ubisoft with the epilepsy filter and Nvidia with no driver support effect the perfectly good code of Luthiers game.

2009? You've been here asking the same question since then? For real? Not been answered. Not fixed. And I thought I couldnt take a hint. Holy cow.

The example of another great simulator shows that even when SLI is fixed it can be broken again in the next patch. They managed to fix it again only after NVidia sent them some documentation after several unsuccessful requests for support. NV did not even talked to them, just sent doc files to figure out by themselves. This happened 2 years after the launch. They were not so lucky with ATI x-fire as ATI never responded to them.

Sim market is too small for both NV and ATI to bother.

Luthier tells on the forum only what graphics developer tells him. The previous graphics developer was fired.

SLI will probably not be available in the 1st beta but may be supported later. This would not mean that it can not be broken again in the following patch as it happened in competitor's sim.

It is reasonable to avoid SLI and x-fire setups at all cost unless it is a temporary solution of adding 2nd cheap 3-year old card to your old one.

It seems that anyone who can not handle his emotions blaming devs for not including SLI into the old graphics engine (before new is introduced) just does not know what he is talking about or deliberately trolls. 1st step - have a stable graphics engine (test beta and fix bugs), 2nd - talk to NV and ATI asking for support if face any difficulties, 3rd - wait till they pay any attention. At least this happened in competitor's camp.

Ataros,
All is not lost. I'm getting about double the fps with Sli as i'm getting with a single card. Those of us that are trying, are getting it to work reasonably well under the current situation. Most of my settings are on high with about 2 on medium working with 2xgts450's which most would laugh at with this sim, but for me it's working. I'm happy at getting 40--60fps with London Attack single player with Sli (only 25---34 with a single card working), over water around 80---90fps Sli. I'm waiting to see what happens with the new graphics patch and the quoted 50% approx improvement in fps. My biggest problem at the moment seems to be with the 1gig V/ram, my indications are that with CoD it is running at max, don't know what others are finding.

[III/JG53_Don]

Why are so many people here talking about an increase of 50%?
When the devs are talking about the patch that nearly doubles the fps, actually its an increase of 100% or near to that

We are talking about total numbers here! There would be even the mathematical possibility to get an increase of 200%, believe it or not

[JG5_emil]

What is the deal with SLI...does it not give any improvement at all?

I ask because I am planning a 2nd 3 Gig 580 GTX so that I can run a 3rd monitor for work.

Are there any negative implications running SLI?

No I haven't been asking since 2009, i raised the question in 2009. I was giving you a history of SLI events, but im sure you knew that.

My GTX590 on this Z68 rig is handily outperformed by my 3GB GTX580 on my X58 rig because SLI isn't working in CloD. If SLI is going to remain broken forever or a very long time I will hold out for the 4GB 680 or the phantom 685 but avoid the 690.
thanks,

SLI and AA will not be fixed in first beta.

[CWMV]

Thanks so much for the quick answer.

Thanks Blacksix, thats good news if the fix is coming at least in a follow up patch.
