A few days ago Windows did some updates and ever since I have been going round in circles trying to undo the damage.
This is a Windows 10 (home) PC which has a Intel(R) HD Graphics 630 on board GPU and a dedicated AMD Radeon (TM) RX 480 graphics card.
Before the upgrade all was perfect, images, video, icons, gaming was crystal clear. Since the upgrade everything has taken on a dark/dim theme and when I play my game it is night! (this game has no night).
I have gone on a massive merry-go-round of installing all AMD drivers, reinstall all AMD drivers, creating an AMD profile for the game, checking Windows settings to ensure resolutions, brightness, contrast, themes are all as they should be.
I have changed every known setting from eco friendly to burn the world. I have done a system restore (which did nothing) and allowed updates to run again. I have changed reg keys to stop windows automatically doing driver updates during windows updates. I have confirmed through the AMD/Radeon utility that my dedicated graphics card is the primary source. I have googled this to the moon and back. Is there ANYTHING I could have missed? System restore only seems to want to let me go back a couple of days so I am guessing that the install of the "features update" for windows was a line in the sand update?
