Hi. I see nobody’s posted yet so as Ive felt your pain (and worse), I thought Id try to help and maybe save you some days of frustration trying to get the triples up to what you would expect. So, just as a quick reference Im running a 149000k processor, RTX 4090 but the fps killer is 3 65” LG Evo oled TVs (2 C3 and 1 center G3). I have struggled mightily getting the settings to where the TVs are stable, 4k or higher at 120hz. With these changes, I can run pretty much everything on Ultra and maintain 50+fps over NYC day or night even with the 3 TVs at 4k or higher in the special modes). Im not kidding, I spent many an overnight period messing with Windows 11 graphics, working with Nvidia 3d settings and all the other resolution settings. Okay, enough of the problems on to the solutions!
I found a couple guys videos that saved me and I actually have been running 6k and 8k inside msfs 2020. Im in uploading the screen shots. I have a video too but I don’t know if I can upload that.
The answers lay in the Nvidia 3d settings from this video.

and DLSS updates in this post: *** This video explains all about what DLSS is and how to update it. Atm it is 3/5/24 and a new version of dlss is out. ver 3.6. Great guidelines for setting up your Triple TVs. Don’t use the msfs performance settings, just how he sets up his 3 screens. also https://www.avsim.com/forums/topic/642554-how-to-get-the-best-image-quality-using-dldsrdlss/page/2/
Good luck. It’s worth it when it’s done. If you need cables I can point you to the ones I found (after spending hundreds of $$) on ebay
