OK, Here are my test results. Using a 144Mhz 28" monitor at 1920x1080 - FPS on Uncapped
My previous settings were on:
Medium, AA 2X - Getting 45FPS in my house
Went into inventory 3 times, not change, no blurred graphics.
Logged off the game, changed settings to:
Ultra, AA 6X - Getting 43 FPS in my house
Went into inventory 3 times, and ran around, no change.
My doll was there for the 1st look in the inventory, and not afterwards on both occasions.
There must be something else causing your issue mate. With PC’s all having different hardware, drivers and OS’s, the problems people are having could have any number of causes. Or maybe I’m the odd one out this time.
I don’t use Ultra most of the time because it does make my card run hotter, but does not cause any loss of FPS most of the time.
Just off to read your link.
Edit - Going to go out looking for a monster to see it the edges are blurred.
