P3Dv3 and SLI

[YukonPete 586]

I have two GTX970's in SLI but they never reach more then 55% usage in P3Dv3. Anyone else experience anything similar or better? Any tips?

I'm in the same boat. I'm picking up a 4k Dell this week, I think that should put them to work a bit more efficiently.

Is that the case when you run SGAA4x or 8x in dense clouds in ORBX regional terrain?  

[YukonPete 586]

It's all the time.  It fluctuates between 45-55% usage in SLI. No matter what I change the settings to it remains the same.

Mine can hit 99% in heavy clouds, rain in dense areas like JFK, etc. Most of the time they're around 50%.

 

If you get it to 99% your fps will start to drop - ne happy they are coasting along.

Let's be clear as there are infinite variables.  You are saying w/ SGAA4x or 8x set in nVidia Inspector, in heavy clouds at maximum density out to 100miles you're seeing 45-55% and at what frame rate?

I find as soon as I open a second window, such as the GPS, FPS grinds to less than 5. The only solution was to disable SLI unless anyone knows a workaround?

I also have 2 x GTX970SC´s from EVGA and they can be pushed to 70-85% with 8x AA and some HQ shadows . Specially the Terrain shadows seems to push the cards .

 

Its correct that undocking panels is still a no go in SLI . Also i havent found the sweet smooth spot yet in SLI. Still better with one card i think.

 

But for 90% of my flights its no problem just using one 970SC even with 8x AA in 1920x1200. I just set terrrain shadows and buildings to off.

No workaround.

With v3 something has changed, with a second monitor in SLI the FPS collapse, with a single monitor the SLI is useless.

I can see my SLI 980's works only if i set SSGS at 4x or more, but i have some issue like fps drops sometimes using SLI that disappear after a system restart.. so i decided to disable it for now.
