Hmm, I thought there had been some tests by a certain individual whose name now appears as "Word Not Allowed" when typed into this forum, even back in the 1.x days showing there were gains under specific conditions (i.e. views outside the cockpit, scenes with high levels of AA especially with multiple cloud layers).

I believe it has a lot to do with individual setups. There are people who claim  no benefit, and I have no reason to doubt them but I've been running SLI for quite a while and I *DO* see a benefit. I notice it most when I am in a demanding situation, high density area with TStorms and very dark clouds, etc.

Flying in fair weather - very little noticeable difference. Considering that the majority of my flights are in severe weather, I'm a happy camper.  I also believe that some people are expecting a FPS increase through SLI - not going to happen. In my case I didn't get an increase BUT it took longer for performance to degrade when I overloaded my system.

Agree,  tested p3d-v3.5 and 3.4  with both 980 sli and 1080 sli , I have a single 1080ti strix oc bought it for xplane and p3d xplane not support sli. Think a get better performance in p3d with 1080SLI then single 1080TI

P3D-v4 ?

With my config I see a real benefit when I fly with medium scenery.

With light scenery all is perfect and SLI do not anithing better. 

With heavy scenery SLI is waiting the data from CPU, and work e few.

But with medium scenery, all the data send by CPU are treated by the SLI and here, I can see a real benefit with or wihtout SLI.

 

To be effective SLI needs a CPU able to give enough to it...

Too bad SLI doesn't use the VRAM of both cards :-(

I would think so because you may want to go SLI ant then what . I think SLI is working now that I have installed NVidia Inspector which I strongly suggest in order to tweeek SLI . An I7*8700k is the best you can get 1151 socket , but you well have to purchase a new MB.Z370 .YEAH your talking some major changes.

SLI works fine with V4.

With detailed scenery , or many clouds or rain I see a gain up to 60% ( triple monitor setup as 2 views ) compared to ine card ( both 1080 Ti OC ).

No NVI installed.

SLI is good but replacing my old 970s SLI for 1080TI was a good move. Dynamic lights and reflections now possible in 4k. Also higher ASP4 and Rex skyforce 3D settings. 

I have 4770K@4.6 and it goes. I have only hit 100% once with the GPU with ASP4 set to max overcast and 250nm draw. 

Night flying has become a blast. 

Thanks Michael Moe

Question for the computer guy, after reading this thread it got me thinking about SLI for VR.

I run a single titan XP with good results using VR. However when the clouds turn into thunderstorms I do notice a drop in FPS spoiling the experience.

Another XP is hard to come by but maybe 2 X 1080ti might help here?

thoughts?

I always got the impression that SLI pays off when there are more pixels. If you have triple screen 4K, most tests show that’s where SLI really makes a difference.  I saw an article about 8k with 1080ti SLI and it made a very noticeable difference.  So in P3Dv4 if you are pushing some extra pixels I bet you see a solid improvement.  For texture loading and autogen I bet it doesn’t do much.

Try this one. Your computer will never have a bottleneck again.

3x 1920x1080 and texture loading is quicker.

As I use terrain , clouds cast shadows icw buildings, vegetation and objects receive shadows it certainly makes a big difference.

LOL... rumor has it when they were testing this setup with P3Dv4.3 it was stutter free and FPS high but the blurries were terrible.
