So what good is it to fix the problems NVIDIA cards were having but make it so the ATI cards have problems instead? I also am having trouble with the new V3 and Firestorm releases. I have not only no shadows but no clouds and royal blue fake water as well. I never had trouble running any other viewers. One of the reasons I have the ATI card is that previously I had a NVIDIA card that gave me lots of trouble with SL. Maybe there are some folks out there who can change computers with every new viewer release but I'm not one of them and I suspect neither are most other people. I do hope this gets resolved for viewing with ATI cards very soon.
