Hey everyone. I just upgraded to an ATI 4890 a couple weeks ago and since then I've been having the following problems:
-when I open up some windows like the contacts window or the flashback window, my entire screen starts flashing black a few times
-in the mission architect editor screen, if any animations play in the editor screen my game begins to lag to a crawl.
I'm on Vista. But none of these issues happened with my old 8800GTX. Is this a compatability problem because the 4890 is new? Can someone help me please?
