First observation, they fixed the bug where if you have a G-Sync monitor, even though you had selected enable G-Sync for Full Screen mode only and not Windowed + Full Screen mode, you would still have G-Sync enabled all the time in both Windowed and Full Screen mode and because of G-Sync enabled in Windowed mode as in, for all applications, that used to cause screen tearing sometimes in Windows applications.
Now when I installed these driver after wiping the old ones with DDU and rebooted, I again saw that G-Sync was enabled everywhere, the trick is to disable G-Sync then re-enable it again for Full Screen Mode and this time you would actually have G-Sync enabled only for full screen apps.
