People using the word "replicated" are missing the point, completely. The resolution-switching controls in Windows are rudimentary, bare-bones. They are designed solely for changing the resolution of Windows and nothing else. But the resolution capability in the GPU drivers is there specifically for other reasons--for instance--to support
Game Resolution of 2d and 3d games, sometimes 30 years old or older--this is far and away different from what Windows needs to do when switching resolutions (let's not forget that GPUs have had resolution switching capabilities since day one--because when you have a GPU you use the GPU to change screen resolutions--not the CPU, etc.)
Here's a quick example of what I'm talking about: I have a game--more than one, actually--that insists on opening a 640x480 screen even though my native res is 1920x1200 atm. Windows *always* wants to open the screen at 60Hz--but I want the screen to open @ 75Hz because that is my preference (for other people it might be 144Hz, etc.) Right now the only way I can get that to happen is to manually open a 640x480 75Hz Windows screen and then run the game.
Wouldn't it be much better, say, if I could make a
game profile that would (a) open a 640x480, 75Hz screen and (b) then run the game--right from a GPU game profile? Of course it would. But the Crimson interface has stripped resolution switching right out of the AMD GPU driver interface! Now we have to depend on Windows or on a 3rd-party application simply to exert user control over screen resolution switching! A terrible idea. The Good News is that if you install the Crimson drivers into the 15.11.1 CCC shell that you have full resolution control returned to you. It isn't the drivers that don't allow you to switch your resolutions--it's the Crimson interface as it sits. Here's hoping they fix that soon.
The Catalysts provide far more resolution switching control to the user than Windows does--which they should since Microsoft doesn't make the gpus or write the drivers for them. I certainly don't intend to ever buy a GPU costing several hundred dollars with which I cannot even change my Windows desktop resolution unless I use Microsoft software to do it--or some other 3rd-party software! Bad, bad idea. If AMD cannot figure out how to greatly enhance resolution and refresh-rate control in its GPU drivers and use the Crimson QT interface at the same time, then Crimson needs to go and they need to start over. Simple as that. Nope, less is never more, imo, and it's really sad to see people
applaud the dumbing down of the products they use.
