and I have to say I'm really dissapointed about the speed and snappiness. Maybe it's just my specific Mac (733, no L3, GF2MX), but resizing, scrolling, OpenGL, most applications and changing between windows is painfully slow, and in most cases SLOWER than 10.1.5... Photoshop (which is a carbon app, I assume) is about the same speed as in 10.1.5, IE (carbon too) is slower on rendering and the GUI is really slow. I tried Quake and got 30 fps avg. Almost one third of what i get in 10.1.5 (I'll have to test OpenGL in different games since it could just be a Q3 problem). Resizing of windows is slow as usually, and even slower that 10.1.5, and selecting icons insinde a window with click-hold-drag results in an inresponsive greyed-out-square which lags seconds behind where you move the mouse around... Well, that was about all the BAD news. The GOOD news is Ink, Audio MIDI setup, some other new utilities (Bluetooth file exchange, ODBC Administrator, etc.), window dragging (smooth as never seen before), popup dialogs, genie-effect, zooming windows, REALLY fast startup and login (!), application startup times and some new preferences here and there. But all in all, I'm dissapointed with the allround speed, and I really hope the problem is just my comp. If anyone others here on the boards have installed 6C85 as well, please report!
