I'll make this brief and to the point:
I have an Acer 28" 4K G-Sync monitor with the correct cable attached directly between the primary of (2) Titan X video card and the monitor. Latest drivers. In Nvidia control panel global settings, G-Sync is enabled for both F/S and windowed mode, v-sync is 'On.' Nvidia Inspector profile had G-Sync on, V-Sync to 'Application setting.' In-game menu has V-sync 'Off.'
This should be the standard setup to use G-Sync instead of V-Sync in DCS.
The result: After the sim begins in an A-10C, I press the 'alt + enter' key combination to get into full screen mode. Instead of the advertised "Buttery smooth" performance, I have very noticeable screen tearing. Additionally, my 60hz 4k monitor is indicating FPS between 125-135 FPS, more than twice its capable refresh rate.
I've searched the forum, as well as Nvidia's forums, and the forum for my monitor. Can any of you G-Sync-savy folks who are having perfect G-Sync performance tell me how to fix this? Thanks much in advance!
