I have an issue with when G-Sync is on and my in-game resolution does not match my desktop resolution with my S2417DG. I get horrible alt+tab lag where I sit at a blank screen for like 4-5 seconds, then I hit the desktop and it's like my PC is frozen for another 2-3 seconds when playing Overwatch. For instance, my in-game resolution is 1920x1080 @ 165, my desktop is 2560x1440 @ 165. If I turn off G-Sync, the problem games away. If I set my in-game resolution is set to match my desktop resolution, the problem goes away. It only happens when the in-game resolution doesn't match the desktop resolution, or if G-Sync is completely disabled.
I've tried downloading the latest drivers and doing a clean install with DDU and have the scaling set to the GPU.
W10 x64
GTX 1060
Dell S2417dg
Edit: Maybe it's an issue with Overwatch? I have other games where in the same scenario (G-Sync enabled, my in-game resolution is 1920x1080 @ 165, my desktop is 2560x1440 @ 165) and alt+tab takes 2-3 seconds and there is no freezing.
G-Sync ALT+Tab really slow?
Re: G-Sync ALT+Tab really slow?
I tested this in Overwatch with an in-game resolution of 1080p @144Hz, and a desktop resolution of 1440p @144Hz, G-SYNC + V-SYNC (NVCP) enabled; alt+tabbing out took about 1-2 seconds with a couple of black flashes, same with alt+tabbing in.
It must be specific to your configuration/monitor. Do you have the Windows 10 Game Mode or Game bar enabled? Also, have you tried disabling fullscreen optimizations for the game's exe? Other than that, the only suggestion I have is to switch to borderless windowed mode (G-SYNC and in-game).

Re: G-Sync ALT+Tab really slow?
Looks like disabling "Full Screen Optimizations" fixed the issue.

Oh, nice. Glad that fixed it.
Windows 10 Creators Update settings seem to have random effect on different setups currently. I have fullscreen optimizations enabled for the Overwatch exe, and I have no such issues. Go figure.
