Did disabling gsync also improve your frame time?

Not the frame time but the fps goes much more high. Before that with SLI enabled with JustuLM profile, fps stay on 50-60 and disabling g-sync goes to 70-80 fps.
What I noticed is in Horseshoe Camp frame time is more bouncing and far from that is better. Even with only one card, frame time in the camp is very bouncing.
I hope someone find a setting that makes frame time more smooth.

Last 3 games I have played all have working SLI profiles, albeit hacks from the community. Borderlands 3, The Outer Worlds and now RDR2 (all working for Pascal though The Outer Worlds and Borderlands 3 are bandwidth limited so I don't think you'll get good performance on Pascal at 4k unless you're on a 16x/16x motherboard).
 
This is the profile that worked for me in RDR2: 
 
Edit: ah, it won't let me post a link, just search on RDR2 reddit for 'RDR2 SLI Settings' by u/SupremeSpez.

i have 30-35 fps too with one card. not at ultra everything tho. Never seen 60 at max settings whatever i do. What cards have u got? think 2080 works better then pascals with vulkan and so on. When i run with sli i get huge frametimes that makes it feel like 20 fps. I tested both drivers with around 4 diffrent profiles. .08 driver has mgpu on as default no need to change anything and it flickers like mad. Found one setting that seemed promising but then game crashed every 10 mins instead. Ill just stick with 1 gpu untill they fix it. Just played for like 4 hours without a single hickup so i guess ill settle for waiting.

 
I went from just under 40-45fps on balanced to 55-60fps on ultra. Both cards sitting at 97+% utilization. Are you running at 4k on Pascal? I'm on 1440p with 1080 SLI and it feels pretty damn smooth. I'll check the frame timings and get back to you.

Hey guys... so, there's a reddit topic about SLI: /r/RDR2/comments/dssli4/rdr2_sli_settings/
 
and I posted there but might as well post in here, maybe get some fresh new ideas
Ill paste it below and, well, if anyone has a slightest idea of what could work in my case, please feel free to respond and at least give me some ideas to work with.
 
2 x GTX 1080 Ti in SLIi9-790016gb ram could run the game on mixture of ultra-high-medium using one card with some decent framerates. Decided to look for ways to enable SLI. Found this topic.Started with the steps from the main post. That indeed enabled SLI. I maxed everything out in game, I could even reach 100+ framerates on 1080p. Both cards working, one on 99%, other one on around 45%- enough to have a beautiful lookin game on full hd. Note here: had to use Vulkan, DX12 with the SLI settings crashes while loading story mode (I can turn on the game, get in the main menu, settings, everything. if I try loading the story mode, it takes forever to load (my loading times on Vulkan are really short) and then crashed to desktop.But- there is a problem. I reach those beautiful framerates on two cards working while I'm on TAA off. And for some reason then everything is so damn bright I can barely see anything. Nights (with all the lights and details and everything) stay smooth. Days are just so bright (overexposure or how do you call it) that its just, well, unplayable.WIth TAA on, my fps drops to around 30 (everything maxed out on full hd)- 31 most of the time, 25 close to the water- and everything feels like a slideshow.I've spent few hours testing multiple settings (which is hard as there's another problem, while using this SLI profile, changing options in game leads to many, many crashes. I actually had barely any problems on the release two days ago, only had one CTD, I think. Here, while tweaking settings, I was actually forced to change some of them through system.xml since I was getting so many crashes) and found no solution to fix that overexposure thingy or leaving the TAA on but without those fps going so low for some reason.Does any of you actually have some suggestions for me? I am willing to spend another couple of hours testing stuff (and hopefully find the solution for myself and others) but I dont really know what else I could do. I thought of disabling the TAA ingame and forcing some AA method through the Nvidia settings or nvidia inspector? Or perhaps something else? Any suggestions are welcome.Oh, one more thing- I've changed few things in that rdr2 profile in the Inspector, everything as it was in the original post and also changed some things here and there but I believe they didn't really affect anything anyway.And, by the way, I actually do not encounter any visual glitches. Nothing flickers in my game, everything loosk beautiful while on SLI. But that damn TAA just makes it a slideshow and without TAA- like staring into a sun.

Still haven't found a fix for my crashing issue in SLI on my 2080 Ti's the moment I continue the story or try to run the benchmark. Tried both profiles, just changing to the strange brigade entry, DDU my drivers just in case and deleting the rockstars red dead folder from documents. SLI just causes me in this game only to crash to the desktop or locks up on a black screen forcing me to end the task.  I'm completely stumped
 
This is with vulkan and 441.12.

I dont even see the HDR option under display settings.

Single card runs perfectly the moment I restore the profile. I don't use HDR so that's off anyway. Even tried launching the game in safe mode and it also crashes when continuing the game in SLI. Tried Vsync on/off same with TAA. Really confused why it doesn't like something on my system in SLI mode as no other SLI game has issues even GTA 5, other games in SLI run very nicely without issues.
 
Only thing I haven't done is wipe and reinstall the game so may give that a go as that's pretty much my last resort.

Good luck. Hope it works. Only other thing I can think of is if your running any overclocks on CPU/GPU/RAM as some games don’t respond well to certain overclocks. For example I have some crashes in Overwatch when I run my GPUs at an overclock that most other games can handle. Another game didn’t respond well to my ram being at 4600mhz so had to bring it down to 4200. Are both of your GPUs the same? I’ve heard of people having issues when doing, for example, two 1080s but one was from Zotac and one from EVGA.

Unfortunately wiping the game fully and downloading it again didn't fix it, both 2080 Ti's are the reference models that I've left stock as they auto boost to 1.9ghz out of the box. RAM is 3000Mhz which is it's stock speed with XMP (small chance the game has an issue with my XMP profile even if it's the first game to do so), and my 9900k is at 5Ghz. I've given up for now  . Even hellblade with a modified nv inspector profile is great in SLI, will have to wait for another game patch and try again.
