Well, if you could get me the other apps that cause this - I could attempt to duplicate those, too.
As I mentioned, DW squeals, SC does not. Using ALMOST the same engine, too - just different versions. Which is beaucoup odd.
EDIT: ADDENDA
Just tried tinkering with settings again and I got the squeal to go away on the X800XL. If I *force* 4xFSAA and 4xAniso, it stops.
Note that these settings did NOT fix it for the X800XT, but it appears to on the XL. Go figure.
I mean, it was clear from the get-go the problem was some weird un-anticipated interaction between the video card and application...I just wish the details of that might be clearer.
And, of course, on either card, SC is just fine.
