I wish you good luck finding another 780 Mike, i found one by chance after bumping into an ASUS rep at a computer store and asked him if could help out, hence my second card, i see all sorts of lessor known brands on ebay for outrageous prices, no thanks..

 

Thanks  B)  . Still 2 GTX780SC would be pretty nice i guess , even in P3D when the official SLI optimize version is released.

 

Can i mix 2 different GTX780ér ? ASUS and EVGA or 2 different EVGA´s ?

2x 780`s from any company is ok, its when you mix different models up it becomes pointless, i have 1 780 reference card and the other is a windforce 780, works fine. doesn't look good but neither does my wife.

No, the prior nVidia profiles do NOT have these Prepar3D SLi entries ... I did check.  I'm 99% certain this IS the driver.

 

Cheers, Rob.

We have an option to select in NVI in SLI : NVIDIA predefined mode in directx 10 : 0x0000002 (contains prepar3d in the long list...)

 

after setected, of course 0x080040F5 (Daylight, Evolve, Monster Hunter Online Benchmark, Squadron 42 - Star Citizen, Ryse: Son of Rome, Lichdom: Battlemage, Prepar3D, Far Cry 4) in : compatibility : SLI compatibility bits DX1x

Again, I refer everyone to the release notes. The new sli options could very well just be a precursor for the profile LM has been anticipating.

Here, finally, a logical comment.

 

Sitting with a 1st gen Titan card and thinking of going SLI but I'm not very tempted getting a second 1st gen Titan card considering it's age vs cost ratio.

 

When Titan X was released I first played with the thought getting one but later decided it probably wouldn't be worth it looking at the expected performance increase vs the high price. I thought a better option would be to wait for 980Ti which will probably perform like a Titan X but at a considerable lower cost.

 

However now with SLI support coming for P3D (or might even already be here) I'm thinking maybe 2 970s would give a very nice boost and at a very reasonable cost. And maybe the boost would be so good that waiting for the 980Ti and use that card for an SLI setup wouldn't justify the extra cost (and waiting).

 

What do you guys think?          

Hi

 

I have just installed 2 x Asus GTX 970 DirectCU Mini ... factory overclocked cards running in SLI and I must say I have seen an amazing difference in performance

 

Smooth as butter and I have cranked my settings up quite a bit more

 

Running P3D over 3 x 26" NEC 16.10 ratio screens

 

I have been trying to get the SLI indicator to show up in P3D but alas no joy  ...... it might be something I am doing but having said that it's definitely SLi'd because I get the green bar indicator up when running a graphical benchmark programme from Unigine

NVidia Control Panel, Manage 3D settings (select a program to Prepar3D), 3D Settings (in menu Bar), Tick Show SLI Visual Indicator?  Shows on next start

What card(s) were you using before this?

 

I'm still wondering if two 970s in SLI is enough to get the best you can get in P3D or would it be worth waiting for 980Ti? Very tempting to go for 970s since that would be a much lower cost and also that is something I could get already today.

 

Of course the 980Ti will be a much faster and more powerful card than the 970 but if 2 970s running in SLI mode will already take you as far as you can get in P3D from a graphics card perspective I don't see any reason spending lots of extra money on a more powerful card.

Another question for you already running SLI, are you able to use SGSS in NI without a serious impact on FPS and smoothness when entering dense clouds?

 

If yes that's great news because that would mean running SLI doesn't only give you better FPS and a more smooth ride but it would also give you a cure for the bad AA in P3D. In my case using SGSS removes the bad AA almost 100% but unfortunately I'm not able to use it with my single 1st gen Titan card because the FPS drops like a stone as soon as I'm entering dense clouds...

hmm - I have a single EVGA GTX780SC ACX which is hard to come by these days and was just wondering if i can have my setup intact if i fing another card to go SLI.

 

Current I have :

 

1 x 1920x1200 (main)

1 x 1280x1024 (for PFD,ND,GTN750 etc)

1 x CDUII 1024-768

 

Thanks

Go to Neweggs store in Ebay. $269 right now free shipping sans tax.

Well shall we say .. I am in the business so I get to try practically anything I want but the last card I had in the system was the full sized Asus DirectCU II Strix overclocked card

 

I decided to try the 'mini card'  versions of the Asus GTX 970 and I love the fact that they neatly fit into an ATX case with ease  .....

 

Bang for buck I really do not think you can go wrong with this configuration!!! and .. without blowing my own trumpet I do know what I am on about!!   

 

They are running well .. not getting hot and hardly any noise from them

 

Cheers

Sounds great Paul but when you say these cards run very cool and will give you a great bang for buck are you then talking specifically about the mini version of the 970 or 970 in general?

 

Also I'm hoping someone will be able to answer my question if you're able to enable SGSS when running 2 970s in SLI without a severe FPS drop when entering dense clouds.

 

And last and again...if going for 980Ti in an SLI setup when that card is released would likely give me a huge performance boost over a 970 SLI setup I might decide to wait for that card and be willing to spend the extra money. However if the difference between a 980Ti SLI setup and a 970 SLI setup is likely to be minimal simply because P3D won't be able to make use for the added power in the 980Ti of course I will go for 970 cards instead.

If you are not getting the green bar in P3D - you are not in SLI mode in P3D. Verify this - install EVGA PrecisionX or MSI Afterburner. OPen the graphs and run p3D - you SHOULD see TWO distinct lines, one for each GPU - they should move roughly equally as the load increases. If one is high and the other flatline - SLI is NOT activated for P3D

End result. I am turning off SLI but keeping this driver. It is not there yet http://www.prepar3d.com/forum-5/topic/v2-5-flashing-lightning-effect-gone-wrong-or-video-memory-problems/

 

That is the issue I am having.

SGSS without a serious FPS drop?

I am smooth at 20 so I am not concerned with FPS drop. If I ran at unlimited or possinly 30, I might see some but why would I do that if 20 works?

 

Interesting indeed if we had the possibility to run proper SLI all the time by just using the correct settings choosing 2 rather than auto.

I've been doing just that for almost a year.

 

That said - this drive *IS* different - it takes longer to get the GPU's up to max than prior drivers. When the gpu's maxed out is when I has fps drop - with the GPU's maxed, cycles were taken from the CPU which impacted FPS. This is with pretty much everything maxed and some heavy ASN thunderstorms.

It's not a "placeholder" there is no such thing in a driver.  But the proof is simple ... when you enabled SLI in NVCP go over to the Manage 3D application settings and you will see SLI selected by default.  If this wasn't "the" driver, then it would NOT default to SLI.  Since it does, this IS the driver.  Now that doesn't mean future optimization will not happen on both sides (LM/nVidia) but like I said, I'm now 99.9% certain this IS the driver.

 

As for the performance difference ... well ... I'm still testing that (will provide some data later).  Testing really needs to be done against a BASE v2.5 12945 as some add-ons cause stutters regardless because of how they design specific elements (i.e. runway lights).

 

I'm not seeing any of the visual issues in SLI mode like others have reported, all visually looks good.

 

The Titan X's do overclock well "as is".

Energy used for my entire PC (including 4K monitor) is about 740-760 Watts under full load when benchmarking.

@Rob:

So are you recommending we deactivate things and slowly reenable to see where SLI is/isn't helping or getting caught up on something then?
