Too many numbers! It was released on 12/13. I knew there was a 13 in there somewhere, okay?
At any rate, new drivers were released the day I made my post, and I tested to see if they fixed the problem, which they did not.
The catalyst Drivers number scheme has a purpose.
10.12 means = year 2010 and month 12 = december
cant be a 10.13 that would actually be 11.01
This issue with dynamic lighting and flickering shadows have been here since day 1 of open beta 1/14/10.
I dont expect this to fixed anytime soon. Minor annoyances like these been here since day 1, and probably be here until the servers shut down (whenever that is, if ever).
Anyways risking a warning for posting in an old, very very old thread, you should try this solution until the dx11 update arrives with season 4.
Set both the max lights and max shadows sliders to 1 less then the max settiing, for example if the sliders went to 10 then you should set them to 9 ok, this helped a lot of people back when the was happening 10-15 times a day, though i am also sure there were people that this did not help.
