Overall, like the Crimson setup but for my setup it's a massive step backwards for Eyefinity users. I prefer my setup as 3 merged screens plus an additional 1, the rest of the family prefer 4 separate screens, so I end up having to change between 3+1 and 4 frequently.
Previously with CCC I had to initially setup how I wanted my screens with Eyefinity enabled, then disable it and set my screens how I wanted them then. After that initial setup, I then simply enabled or disabled Eyefinity with a couple of mouse clicks and the screens would be how I wanted them.
With the new Crimson, I have to setup Eyefinity every single time I enable it. I realise this is only an additional 4 or 5 steps, but it's infuriating when going from a 2 mouse click process to a 9 click process. Also, each time I turn off Eyefinity, I now need to go into Windows settings and re-enable 2 of my screens, then rearrange them, then finally set which is the primary screen.
Setting and disabling Eyefinity still works, but as I said for me it's a massive step backwards in ease of use. I'm hoping I've missed something obvious and there's a shortcut, but I'm not seeing it. I did see a new option and tried setting in the game options to launch a particular game with Eyefinity, but sadly this did nothing and the game still launched in a single screen rather than activating Eyefinity and then launching the game.
Overall, like the Crimson setup, as I said, just this is annoying.
