RE: Performance problems while mouse over objects

I have the same issue: the game crawls at a single-digit FPS when mousing over an object (i.e. when it draws the pretty blue outline around objects in the game).
Some people on the game's forums reported the same issue. Some people claimed that changing the shadow quality setting fixed it, others claimed changing HardwareClass to 2 in D3Prefs.txt fixed it. Neither of these worked for me.
