My game runs fine in general. Have 45-100 FPS usually, but in the cities like Mournhold, or any other crowded city gets my game stutter, sometimes it happens for no apparent reason but that's not that annoying because it goes as fast as it comes. In the cities though i have to hang around for a bit for it to go away, for it to load everything i assume. What I also noticed is that latency sometimes goes to red point when it happens.
Already tried changing values of these:

SET RequestedNumJobThreads "-1"
SET RequestedNumWorkerThreads "-1"

to zero. While it helped it caused another annoyance. Everything loads fine and fast, but when i try to hit something with a staff, there is no animation what so ever, and it doesn't even hit, just plays the sound and that's it, and while spells do hit, they miss the animation, character waves his hands and such but there is nothing beyond that.

I tried everything I could think of, I tried all the guides, did some tinkering myself, but nothing helps. I know i meat the requirements, not maximum, but I'm somewhere in the middle.
Just wondering if I'm missing something, thanks.
