Does anyone know if the new v4 will finally make full use of SLI?

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 :-(
