November 19, 201411 yr I use only 1 screen 22 inch. That maybe explain less gpu usage. Does SLI target only on multyscreen, or also single screen can benefit in terms of FPS increase and performance in general?
November 20, 201411 yr SLI works quite well across all my 3 monitors, just need to be sure how you configure them.
November 20, 201411 yr All is done now with NV and AFR2. I will bring findings when more secure of the testings. That didn't work for me ... at least no significant difference vs. 1 GPU. If you can provide details of your exact settings and GPU, I'll certainly try again. Cheers, Rob .
November 20, 201411 yr Hey Rob, I will come back with more when I am back in the cockpit tonight. What I did basically was I tried the AFR friendly sliu way first and checked what I got, then keeping all same I tried with std prepar3d.exe plus settings in nVida conotrol planel and editing the parameters through NVinspector and got basically the same in FPS improvement, so I concluded that I could just stay with this. I moved as well to latest nVidia driver and no problems so far. My current focus is on keeping my VAS low as with prepar3d + 73xxx +orb x + some airports it can be a challange to avoid oom's. I use 3 monitors for my cockpit, one is view, and 1 for CDU+lower planel and other for PFD's+clock, so a total of 5 undocked panels.

Hello Rob, here are my settings, hope the link works: https://drive.google.com/folderview?id=0BxnM6kEWjktQaWdOQXJkUTl2ak0&usp=sharing
November 22, 201411 yr Hello Rob, here are my settings, hope the link works I'll certainly take another shot at these, swamped with work right now, but thank you for taking the time to post the settings. Cheers, Rob.
November 22, 201411 yr Migrated to P3D V 2.4 shall give this a try . Get my second 980 shall modify it like the first card first. Its gone be a very strong 2XGPU setup , approx 10% more gpu power than 3X Titan. http://
November 22, 201411 yr The AFR 2 setting can only be choosen in the NV Control Panel when NV Surround is off. And my setup uses NV Surround on a 3 monitor wide outside view. I have read that when choosing it and then reanabling NV Surround the setting is remembered even when it's hidden. That might do the same as LuisClement has done through NV Inspector. Did not try it yet as I am working on my cockpit right now. 5950x3d 5.4-5.7 GHz - Asus ROG 870 Crosshair Apex - GSkill Neo 2x 24 Gb 6000 mhz / cas 26 - MSI RTX 5090 Gaming Trio OC - 1x SSD M2 6000 2TB - 1x SSD M2 2800/1800 1Tb - Corsair 5400 case - Corsair 360 liquid cooling set - 3x 75’ TCL tv. 13600 6 cores @ 5.1 GHz / 8 cores @ 4.0 GHz (hypterthreading on) - Asus ROG Strix Gaming D - GSkill Trident 4x Gb 3200 MHz cas 15 - Asus TUF RTX 4080 16 Gb - 1x SSD M2 2800/1800 2TB - 2x Sata 600 SSD 500 Mb - Corsair D4000 Airflow case - NXT Krajen Z63 AIO liquide cooling - FOV : 200 degrees My flightsim vids : https://www.youtube.com/user/fswidesim/videos?shelf_id=0&sort=dd&view=0

Did not try it yet as I am working on my cockpit right now. Will be interesting to see your findings, I see that not always things work as they are said to be. For example if I read Nvidia Q/A for SLI it states that only 2 monitors are supported for multi-monitor in sli but I am using 3 monitors for my cockpit with no problem, the main view one with the focus selection to get most of the 3d acceleration, so we never know. I would like to try to add a 4th one and then have two for surround, main view and 2 for my nd/pfd/cdu views as I have.
November 25, 201411 yr Will be interesting to see your findings Unfortunately still no go for SLI on my single monitor setup ... performance is identical when using your settings on latest 344.75 drivers and latest NI. Will just have to hope nVidia deliver SLI drivers sometime in the future, LM have passed the ball to nVidia, so I continue to wait. Cheers, Rob.

November 28, 201411 yr @Luis, 1) Could you please provide a FLT file (scenario - location/scenery/aircraft - VC or not) setting where you get SLI improvement and with before/after FPS data ? 2) It seems that monitor #1 is your focus monitor - is that the only monitor that gets SLI acceleration? 3) Are the UNDEFINED values values that you entered in NI? (I don't have a second Nvidia video card myself yet to try these SLI settings) 4) Any chance you could try Surround (requires three equal monitors) and/or just three separate monitors with separate P3D 3D views? Thanks for your testing info! whitav8 PC=9700K@5Ghz+RTX2070 VR=HP Reverb| Software = Windows 10 | Flight SIms = P3D, CAP2, DCS World, IL-2, Aerofly FS2
