Shivering Isles Horrific Stutter FIx?
Anyone have any insight into why only Shivering Isles performs this badly, and how to fix it? Where as I am getting good frames most of the time in main overworld (120-130), I will very often stutter to frozen for a few seconds in the Shivering Isles overworld. Dungeons and interiors are fine.
