I skimmed through you playing with settings. Did you ever try changing Anti-aliasing off of TSR?
That one can be problematic for certain GPUs.
Also if it not too much trouble, I'm curious if turning "Dynamic Resolution" off and back on again has any positive effect.
Thanks.

I switched to FXAA and it helped a little but shadows seem to be the most impactful thing so far, although I didn't notice any visual difference between medium and high. When I was disabling them during the stream it produced much less difference than off-line, but I guess this is something I have to figure out myself. I tried using the build shaders option but it didn't seem to do much. Dynamic resolution settings gives me no performance difference whatsoever, not sure how is it handled.
Is there any chance for FSR3 support (upscaling, don't really care about the frame generation) in the future? I used it while playing Ghost of Tsushima and it was very beneficial, could grant better results than the current scaling system.
I did some more "extensive" tests today and the culprit seems to be the 6GBs of VRAM my GPU has, which - no matter the settings, be it in game, or in Nvidia Control Panel - always stay at 5.5GB so it makes streaming impossible and GPU often has hiccups even if I am "just" playing. I think this is the bane of UE5 itself and I'm just unlucky. Doubtful this can be fixed, every game on this engine seems to just eat through the VRAM no matter what type of game is it or what settings are used.
From stuff that probably can be fixed, on save reload game seems to be constantly trying to load or unload some assets or post-process effects even if the build shaders option is chosen at the game's start. It causes stutters, drops frames noticeably and slows the game, Control Panel reports 100% 3D usage, can be manually "repaired" only by exiting the game and loading the save back from actual main menu.
