Ok so I did full STEP: Core build and added Requiem, REGS, some weather mods and now i run into some problems like: 1. Sometimes game window turn black and go back to desktop, I can still hear game, after a while it goes back to game (sometimes don't) 2. Sometimes when I horse ride suddenly hooves sound mutes, after a while it goes back but its not playing repeatedly like it should, 3. Sometimes when for example I come back to Whiterun from dungeon or so buildings take long time to load, I had to stay still and suddenly buildings appear, until that I think I only see buildings distant models. And yeah sometimes I get random CTD/ILS - still trying to figure out why. Also my VRAM is almost always operating on 100%, but I get almost stable 60FPS most of the time. Any ideas how to deal with those problems? PC Specs: 8GB DDR3 1600MHz RAM ASUS GTX 560 Ti 1024MB Intel Core2 Quad Q8400 OC 3.2GHz Load order (managed by LOOT):
