SLI config working again in V4.1

Not that I noticed Stephen. Of course, I lock at 20 so I wouldn't see any increase and smooth is smooth at any FPS. What I do notice is that the Ti doesn't seem to work as hard as the SLI 1070's. Same situation wher the SLI would giver me 50% usage on both, the Ti is around 35 or 45%. That card is a beast.

I imagine so!

With SLI you have nearly double the noise, heat, and juice running. I bought a reference GTX1080 which easily overclocks with MSI Afterburner that runs the core clock at 2100Mhz and memory at 5500Mhz but temps seldom exceeds mid 60s C.

The thing is, when I analyse the 8 (4+4HT) CPU threads (2700K at 4.935Ghz) they are running at or near 100% as is the GPU which is showing 100% fully utilized. I theorize that if I drop in another GTX1080 in SLI I have room for it's output to grow quite a bit.

If I had your processor, or some of the new ones coming up I expect that a 2080 (or 2x1080) :) might be needed! 

Kind regards,

PS: What does happen to your FPS and smoothness when you set unlimited? I expect it would be going so fast your watch runs backwards...

I'm running 1070 SLI mode now with good performance.  I think SLI was a NVidia marketing effort to get you to buy 2 GPU's instead of one.  Tech today is good enough to do a single good card like the 1080ti so I will dump the SLI soon.  Lower Hard / Soft resource requirements also with less noise.

 

Cheers

I gave up on SLI "performance mode" as it seemed too dependent on nVidia driver versions ... it also has some strange side affects generating incorrect z-order where I would see building/ground objects render in front of clouds or in some cases PAPI lights wouldn't render at all.  Not to mention I had to disable it for use with XP11 and other flight sims.

BUT, it's great to see some positive reports on SLI.  I would love to see someone post some timeframe data with and without SLI using SSAA and DL (same flight scenario) ... Vsyn On/Off.  Who knows, maybe I'll buy two V100 GPUs instead of one when available.

Cheers, Rob.

Hello Rob, 

Quick question for you if you have a moment. I’ve always found your 4K settings very handy as a basis for my system. Would you by chance have an updated version posted somewhere for V4.0 or V4.1? I checked your website but didn’t see anything new there. Thanks for your time.

Yes, take a look at my signature below... P3DWiki or this link: http://p3dwiki.com/graphics.html

Select one of the 8 situation/tabs that best fit's your type of flying (GA Rural Night, GA Rural Day, etc. etc).

You may also want to try 8XMSAA rather than 2XSSAA or 4XSSAA.

Cheers, Rob.

I saw Titan Pascal 0.0 : Are you in SLI titan XP ?

Hi Pete, I’m the Dutch guy you met at Cosford Flighsim show at Prosim stand.. ( remember the selfie haha ) May I ask you why you have decided not to go for your original plan to use 1 card per projector  but rather use them in SLI?

Simply because first we tried one card per projector, and we saw more stutters and overall poorer performance. We are just guessing that this is because the data needed for the displays has to be fed separately to each one through a possibly limited channel, so afftecting CPU performance. By having them all on the one card and using SLI to allow that card to use also whatever resources it could to help, and such data transfer is taken off the processor.

It definitely appears that no matter what clever visual technology you throw at P3D, at present it still ends up being processor limited. Maybe that will change eventually, but I expect it would mean a move to DX12.

Many moons ago yes, but I've gone thru many nVidia driver updates since then and new P3D Version ... I haven't bothered to re-test with V4.1 and latest drivers.  Lost the desire to continue with SLI because it was so driver dependent and problematic.  That's why I was asking if someone would do some timeframe testing with and without SLI using SSAA and DL and post all their results and data.

It's pretty rare to see people bother to go thru the detail analysis (showing all the settings, add-ons, result files, etc. etc.) that I go thru ... not a criticism because I know it can take many hours and even days to run thru apples to apples testing to get accurate information. But maybe someone else can take the task on and run with it?

Cheers, Rob.

LOL, strangely enough, it induces stutters. If I lock at 20 or 30 I'm good to go but unlimited or over 30 locked gets choppy. Did the same with the SLI setup.
