Maybe "exclusive fullscreen" works in new driver? Or maybe this new driver kind of broke Win10 Game Mode or "fullscreen optimizations" or did something to DWM. On my side of the things, I had nasty problem with multitasking since MS introduced Game Mode. Any time GPU was fully utilized by game (which was focused = controlable by keyboard/mouse), other windows requiring GPU became choppy of temporarily frozen. Clicking to non-game window/desktop allowed everything to run flawlessly (until focus is returned to game window). MS simply gave too high priority to game over everything else and disabling Game Mode did not help. With this new driver it works much better. It is not as good as when there was no Game Mode, but it is good enough. It is not Legacy Mode. It is like expecting HD 7970 to get opportunistic boost feature. Or get software feature for which it does not have HW support. In case of VSR it is AMD's fault that they can't do it for older cards. But only due to having that stupid implementation where image is sent at higher resolution to screen instead of being precisely downsampled by GPU. And then sending image at native screen resolution to screen. AMD's method is severely limited on IQ side by monitor's scaler and on available resolution side by GPU display output, display cable and scaler in screen. Should have been fully software solution. When SoftTH can do that, AMD should too.
