I have since alleviated single GPU under-performance. It seems like Single GPU rendering is now performing better than AFR1 and AFR2. AFR1 and AFR2 appear to be negatively scaling. FPS at Dragonsreach Stairs:SLI 90-100FPS (Stable)1GPU 100-110FPS (Pretty Stable) Main Menu (This is where things stop making sense):SLI: 420FPS1GPU: 2000FPS escMenu:SLI: 450FPS1GPU: 2500FPS While the game is now playable, the fact SLI isn't working and my FPS could potentially be higher is still a problem. There must be a definitive answer as to why I am seeing intense negative scaling with AFR1 and AFR2 enabled. Edit:I'm not sure if it means much but does my PhysX setting matter?

I was so close to giving in... But then stuff got weird. So here's a little progress update for ya. First off, thank you so much for taking the time out of your day to help me with this. I can never thank you enough. Secondly, my next few tests garnered some really weird results. FPS was taken form the Dragonsreach stairs just so ya know. Its a good FPS ravine so you can get a idea of what minimum FPS to expect in game. The further you are form 60FPS, the more headroom for modding I say. Oh, and I'm not sure If I mentioned it here but It seemed like I was experiencing allot of under performance even on 1 GPU alone at first. Initial test: SLI 50-60FPS (Very sporadic/freq drops to 30-40FPS, 17%CPU)1GPU 50-60FPS (Very sporadic/freq drops to 30-40FPS, 17%CPU) After disabling hyperthreading:SLI 60-70FPS (Stable, 33%CPU)1GPU 60-70FPS (Stable, 33%CPU) Applying your profile settings and reinstalling the game (Latest test):SLI 90-100FPS (Stable)1GPU 100-110FPS (Pretty Stable) Main Menu (This is where things stop making sense):SLI: 420FPS1GPU: 2000FPS escMenu:SLI: 450FPS1GPU: 2500FPS ^These new numbers are just plain weird. 4-5 Times the FPS on one GPU? WHERE ARE THESE FRAMES COMING FROM!?? Scratch that. WHERE ARE MY SLI FRAMES GOING! On a serious note, I have no idea whats going on here but while SLI is screwy, It seems as though single GPU FPS is within normal boundaries for the card and no longer under-performing. Semi win? At least FPS keeps going up right? ^-^ I'd say we've got a lead now. We know my SLI can function on my system (and quite well at that). SLI negative-scaling is nothing new and probably has a definitive cause. Only question left is what's causing it and how to fix it so frames go up instead of down. I'll do my best to gather more data and mess around with SLI settings in the mean time. This may very well yield some promising results.

My GPU seems to have come somewhat stock overclocked. Its already boosting up to 2Ghz so I think I'll avoid touching it for now. So under-clocking had no effect. I don't know what I was thinking. Any chance you could send me your profile just so we can rule out any last possibilities before I decide to hang myself? I'm gonna re-install the game too while I'm at it.

>Does SLI work in any other game I've gotten it to work on multiple benchmarks. I figure that's proof enough. Here's my 3D mark SLI score: I also ran It on one card just to be sure and got about half the score. Also did Superposition with SLI on and off all the while using a Nvidia inspector profile for it.. >I rather suspect that you will not be able to mod Skyrim enough to overload a single card I wouldn't be here if that was the case. Just after a bunch of 4k retextures and SMIM and I'm down to 30-40 FPS average. I think I can safely conclude that even the single GPU is under-performing. Considering my Overkill setup, this game has no excuse not to run at 200FPS minimum... I recently had a theory though... What if my GPUs are too powerful for the the game, moreover the CPU itself? Considering the fact Skyrim only runs on 2 cores, what if the master GPU is stealing CPU time from the skyrim host process thus resulting in a slowdown of the game engine and the apparent lack of any SLI improvement. I don't know if this is logic but if I Undervolt/Underclock my Master GPU could this cut down demand for the CPU and reduce any bottleneck my Juiced up card may be creating? This would theoretically shift the bottleneck to the SLI bridge but allow the CPU to better Utilize the GPU performance and actually reap the benefits of SLI. i hope this just isn't the sleep in me talking.

I took a look at the manual. Turns out all my PCIEs are X16 capable and because I run a 28 lane CPU this unlocks x16 and x8. I put the Master GPU under load with sli off and the bottom cards fans started spinning up. Checked out which card was under load in GPU Z and it was the bottom one running in X16???I checked the slave (top card not under load) and it says it's running in x8??? Weird right? I'm as confused as you are. Apparently this motherboard has the capacity to run 3 way sli. I need to look more into this but It may just be a standard for 3 way SLI boards to make the middle slot master during SLI and configure the lane speeds accordingly. Even if the bottom card (middle slot) is the master and my monitors hooked into it, it says its running at x16 so there should be no performance loss right? On a side-note, I don't know who's Idea it was to place the third PCIE slot by the superhugeass motherboard power jack but they should be fired. Only wafer fin water block GPU's could ever dream to fit in that slot. Back to Skyrim: I disabled hyper-threading and i'm honestly surprised it did something. Apparently Skyrim is hard coded to run on two cores. It seems like Skyrim was using threaded cores rather than physical cores so only 1 physical core (two threaded cores) instead of 2 physical cores (4 threaded cores). Some others mentioned having this issue here. I retested and the earlier CPU usage of 25% was way off. I was looking at entire CPU usage and not the actual process usage. As a result of disabling hyper-threading CPU usage has gone form roughly 17% to 33% and average FPS has improved by about a third. Not exactly the double performance boost I was hoping for, but on the other hand fps is far more stable now and CPU usage is at what it should be considering the game should be running on 2 out of my 6 cores. Unfortunately running on one GPU vs SLI still does nothing. The fact the game is essentially using double the CPU power for only a third FPS improvement seems even more wrong than before imo, and the double GPU utilisation for 0% FPS increase still makes me feel like I'm getting scammed. How bout this. You think undervolt/underclocking my GPUs would do anything? It seems really counter intuitive, but what if my GPUs are too powerful for the the game, moreover the CPU itself? They might be stealing precious CPU time from the skyrim host process thus resulting in a slowdown of the game engine and the apparent lack of any SLI improvement. Stupid but worth a shot right? xD I could also try overclocking one GPU and see if that increases FPS when running off it.

From the looks of things, what this guy says probably holds true for my board. I'm going to try and find the manual so I can validate this but its plausible that my motherboard just runs the bottom GPU as the primary card when In SLI. It took some cheesing to get onto the bottom GPU but I did it. here Unfortunately this still didn't fix the problem. I figured I should try monitoring my CPU to see if there is any bottle neck. I'm no expert when it comes to these things so tell me what you think. https://ibb.co/gOpzFQ Now if this is a bottleneck, I have a 6core CPU with hyper-threading enabled. thread 0 and thread 2 seem to be doing most the work. This is just a theory and It may sound pretty dumb, but wouldn't disabling hyper threading essentially leave me with 6 twice as strong threads? This sounds like troll science to me but if the game needs more power per thread, recombining em seems like the most logical option.

Uhhh. I'm having what this guys having. https://forums.geforce.com/default/topic/951844/graphics-card-question-geforce-1080-sli-mixed-up-/

Weird. 1080 Ti (2) happens to be the top card on the motherboard closest to the CPU. I thought that was suppose to be the primary card. I have no idea why it's showing up as (2). Arrow pointing at the card my display is plugged in to: https://ibb.co/f1pSkQ When I try switching it to the lower card (1080 Ti (1)) and rebooting my monitor doesn't detect it. Edit: I suck at using hyperlinks. Sorry. Fixed it.

Sorry for the confusion. Im basically having this issue in both Oldrim and Newrim. Oldrim with nvidias settings, Newrim with the suggested reddit settings. I've been posting my issues all over the web for the past few days on either game, trying to reach as may people as I can who may be able to help. I forgot that this specific post was concerning Newrim and partially confused the two in the process, hence I edited my last reply in the hopes you hadn't seen it yet. You of course had beaten me to the punch but don't worry though, i saw your last reply before you deleted and it is still holds validity. Everything should be enabled: https://ibb.co/e07MUk Both cards under Load: https://ibb.co/koMY75 I've managed to get 3dmark benchmark to run in SLI. I think I can now safely assume this is specifically a settings based issue. The GPUs must not be in the right SLI config for the game. I must have goofed somewhere. Single GPU Score: https://ibb.co/euuRUkSLI Score: https://ibb.co/joyyaQ https://ibb.co/euz4FQ This is how I have 3dmark set up in Nvidia control panel: https://ibb.co/htJs25https://ibb.co/fLw1vQ I also did a Superposition4k benchmark in SLI using the method someone mentioned here: http://www.overclock.net/t/1627726/unigine-superposition-benchmark-now-available-for-download/230#post_26038574I won't lie. I f***ed the install and lost all my profiles but luckily I had em backed up. Here's the results anyhow.Single GPU: https://ibb.co/g3O9h5SLI: https://ibb.co/hkyWvQ Lets focus on Oldrim for a second because really, Nvidias own settings should be working and their not. I'll show you exactly how I have Oldrim set up. You may be able to deduce whether something looks f*#@y.

I'm using the SLI profile for skyrim from reddit that everyone uses: https://www.reddit.com/r/skyrimmods/comments/5ahj4m/heres_how_to_enable_sli_in_skyrim_special_edition/ The problem at hand is far worse than I had originally thought. My SLI isn't working in general. I tried numerous benchmarks and modern titles and got pretty much this every time: Running in SLI: GPU1 Average Usage: 90% GPU2 Average Usage: 90% FPS: 179.8 Running single GPU: GPU1 Average Usage: 90% GPU2 Average Usage: 0% FPS: 186.2 While both GPU's are performing at maximum capacity and frequency there's no FPS difference. Its apparent that my SLI isn't set up properly in general otherwise I'd see at least some gain form application to application. Inversely, if it was a bottleneck I should be seeing some down-clock from my GPU's. Do I need to enable SLI in bios or something? This is a new PC so I may have goofed the setup. Please help me fix this. You're my only hope. Side note - 1080TI sli does work in skyrim Furthermore, I know SLI is overkill for Skyrim but I do need it considering once I mega mod my game that will push my average fps down to 30 if I were to be running 1 card. I plan on capping my frames once I know SLI is actually working. I would have course rather get SLI In general for all my applications first however.

UPDATE: After some bench-marking in Unigine Heaven it seems like my SLI is f*#@ed up or something. I get the same FPS when running SLI with both GPU's maxed and not running SLI with a single GPU maxed. I'm going to try downgrading my drivers to see if that will work. EDIT 2: Old drivers didn't fix anything. I also tried the old uninstall everything, remove GPU's, and install one at a time trick but that didn't work. If anyone has any ideas as how to fix this please let me know!

Thanks for the reply! I have followed your instructions to the letter and while I do see a slight FPS increase the SLI still seems to be broken. After some more testing I have found the SLI to be acting far more peculiarly than I had originally thought. At first I had thought that It was simply halving the usage across both cards but from the looks of things It's actually putting in twice the work in order to put out same FPS (raw FPS that is with frame rate uncapped). This is GPU usage when running SLI through Nvidias Elder Scrolls V: Skyrim profile (60 to 70FPS): This is GPU usage when running on one GPU (60 to 70FPS): While I know I could just run the game off one card and still get 60FPS stable in vanilla, I plan on ultramodding my game down the line and I know this will tank the FPS and raise temps. Here's the profile i'm using. Maybe its wrong somewhere?:

Title says it all. I've been trying to enable SLI in Skyrim with my 1080Tis using Nvidia Inspector but nothing I do seems to work. OSWindows 10ProcessorI7 7800X (OC 4.4Ghz)Memory64GB DDR4 (3000Mhz)MotherboardAsuz TUF X299 Mk2Graphics Card:GTX 1080Ti SLI FPS in game varies from 60 to 100FPS (depending on location) which is very low for my spec. 1080TI SLI should be running at about double this for Skyrim. Changing resolution does very little to effect performance. Each GPU is only performing at at 35% usage and my CPU is at 20% usage. All my drivers are up to date and I am not using ENB. This is just straight vanilla skyrim. skyrim.ini skyrimprefs.ini It should also be noted that within Nvidia inspector I did enable Force AFR2 and in Nvidia control panel under SLI rendering mode I have Force alternate frame rendering 2. I can run other games 4k SLI no problem so I'm fairly sure this isn't a bottleneck issue. If you have a solution for this, questions, or any suggestions as to what should try please get back to me! skyrim.ini skyrimprefs.ini
