I found strange issue in my game.
I start new game at prison, look at the torch on the wall and my FPS goes down to 8 (from 40).
FPS drops if I look exactly in that direction !!!
If i move my "head" at some degrees to any direction, FPS return to normal.

I uncheck in OBMM all mods, but nothing was changed.
I remove whole "meshes" folder - nothing.
I remove whole "textures" folder and bug has gone !
After that, I remove "characters" and "dungeons" folders only (from "textures" folder) and bug was solved.

How I can define which textures exactly cause this bug ?
How I can define all broken textures ?

PS: my video card is: Geforce 8800GT / 512,
my processor is: Core2Duo 2,8Ghz.

Some bug was occurred and my topic started twice.
This one must be closed, sorry.
