No, nothing like that. No 'snow' at all.
I ran the ATI TEST.EXE program, among its other features it tells you
what the timings of your installed modes are. So, at some point I may
use that data to get 75MHz 1024x768 working properly. But, 65MHz is
fine for now. :-)
I'm tempted to try out those 1152x900 numbers though....
