May 24May 24 Ray, perhaps this could be pinned for future reference as people migrate to the newer video cards please? Edited May 24May 24 by Ian S Ian S

Also, I can't find these settings...Disregard, I had the latest stable version. The instructions require a pre-release version (v3 and higher).

May 27May 27 According to the Prepar3d forums Nvidia is aware of this and the fixed was supposed to be in their next Game Ready Driver version 610.47. Tried the new driver and it reset the Prepar3d profile and had to use the profile inspector to change it again to get the effects to work. Looks like a permanent fix is on the way though. Specs: black box thingy with spinning fans, lights and a bunch of wires that go to screens with pretty colours and a keyboard with many keys. The black box thingy also has a push button activated coffee cup holder. John C.
