After spending the last two days trying to figure out whats been making my system dive headfirst into a memory leak, that eventually crashes my game or freezes it, I'm pretty sure I narrowed it down to this..
I remember I read somewhere a guy saying "Don't edit your ini, it's a bad idea" Well it kind of is..
Most of what people will tell you to do is very untested and very hypothetical..
I just did a fresh install of Skyrim and tested it with the ini adjustments for both files (skyrim and skyrimperfs), like shadow res increases and multi sampling, lod, etc.. I had an fps hit but they did not lead me into a memory leak situation.
I run very extensive mods for HD textures, lighting effects, giant giants and dragons, monster mod etc.
All the kind of things you know are going to hurt performance but none of them lead me into the memory leak..
uGridsToLoad=7 is what I have mine set to and it seems to be fine. I wouldn't go any higher or I bet you risk the same kind of memory leak issue.
Point is beware of the ini tweaks and if you run into some serious stability issues, Put the cell buffer back to default and try it out..
Put your inis back to default or some of the more obscure settings back to default and see what it is..
It's not always the mods making you crash or run bad, it's what your doing to the inis..
I was crashing like every hour or so until I did this so I hope it helps someone..lol..
Also If You are having the INVISIBLE WATER GLITCH.. Go back into your skyrimperfsini and enable dept of field
( bDoDepthOfField=1 ). If you disable it, water becomes invisible when you are submerged.
