As you can see i edited the post after testing with stock cpu settings, same thing, i still have annoying lag spikes. CPU clock makes no difference I updated my SKSE to 1.7.1 ENB? Like RealVision ENB? I thought this only makes your game more performance hungry? It maybe helps with visual effect but are you sure this is going to help for lag spikes?I watched some video on youtube and maybe i should mess with uGridsToLoad so i won't be able to se objects rendering because it is happening further away from me. I have no lag spikes in dungeons, i have no lag spikes in cities, i have no lag spikes while i am inside house, i have lag spikes only while i am outside in open world. So my sentence about lag spikes appearing with enemies may be wrong. While i played yesterday, snow storm started and my game freeze for 2s then during storm my fps was stable all the time at 60fps. Maybe it is problem with some of mods who affects open world. So it might be Climates Of Tamriel or Skyrim Flora Overhaul. I am not sure how to check this, should i reinstall game, try game without mods, see if i have lag spike, them install mods one by one and see which one of them is making lag spikes, it will take some time but i don't know other way how to check this, what do you think?
