So I realize that this thread is almost a year old, but I just rebuilt my computer, and having played Skyrim for two years without too many graphical mods, I figured it would be relatively simple to just add some graphical overhauls to my current mod list and my computer would be able to handle it.
Well, having gone through the installation guides provided by STEP, my computer can in fact run the game in Ultra HD at around 60 fps even through the stress test of the Skyrim Performance Monitor (Everything except the final environment with over 100 actors all trying to fight which I could never get to load).
Similarly, when I have all of my content changing mods installed, the game runs just fine, but if at any point more than something like 1.7 GB of RAM is loaded in one continuous section the game will just hang at the loading screen. (The loading animation will often continue to play but I can see that it has stopped accessing my hard drive through the Performance Monitor, and no more RAM is being loaded).
Provided I load it in small enough chunks I have successfully gotten to 3.5 GB of RAM and 2.1 GB of VRAM loaded at one time at 60 fps, but even with many of my graphical mods disabled I cannot load games outdoors without first loading a game indoors, and with the graphical mods enabled I cannot even enter an outdoor environment at all.
I've been searching for a while for ANY sort of real solution to this problem. Obviously the game is LAA because it can access up to 3.5 GB at a time, and obviously my system can handle the mods...Â
