Crash on alt tab when using DX11 native resolution /w Full Screen enabled
I'm playing on a 1440p 144hz GSync monitor and noticed that GSync wasn't working after the latest patch. I alt tabbed to see if there was anything on the forum, and when alt tabbing back to the game the display driver crashed and then recovered. This is when using DX11 mode with my native refresh rate (2560x1440). DX12 mode works fine with GSync and no crashes on alt tab.
If i delete my settings in the My Documents folder, the default 1920x1600 resolution works fine with GSync and no crash on alt tab. As soon as i change up to native 1440p, the GSync and crashing issue is back. This issue was not present before the latest patch and there has been no changes to my hardware or drivers since i started playing, using the latest NVidia driver on a GTX 1070.
Looks like a solution has been found by another user! (MisterGarzok)
On Windows 10, go into Settings, Gaming and make sure the ''Record Game Clips, screenshots, and broadcast using Game Bar'' is set to OFF.
Then uncheck both ''Open Game bar using this button on controller'' and ''Show game bar when i play full screen games Microsoft has verified'' <-- most important one.
I can now alt tab without issues on DX11 and GSync works again. Awesome.
