Hello I use x3 4K Tv and i run the sim between high/ultra settings. The LOD (set to 100) have the most impact in performance… i guess you know it!
My specs : 4080 RTX, 5800x3d, 32Gb ram
I plug x3 TV on my graphic cards, and i use x3 USB/video adaptator from Startech for PFD/ND/ECAM…
So yes you can run the sim in a good condition (25 (town) /45fps (sky)), Frame generation, DLSS only work on main screen, my main resolution was downgrade to 2880x1620 and my sides monitors have 1440p resolution (both) otherwise it’s impossible for only one graphic cards to run x3 4k TV on the sim…
