G-Sync issues

[Sn8ke]

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!

Edit: This seams to be a problem for many people with new/updated drivers. I did a revert/clean install of Nvidia's 353.03 drivers, and G-sync seams to be be working perfectly. Others have reported G-sync to work in drivers 355.82 and possibly others respectively. It appears G-sync either works or it doesn't with certain driver releases. Is this a known issue?

on my side G-Sync works only with vsync OFF (in nvidia settings AND game settings)

I have an Acer XB280HK 4k monitor btw.

Thanks for the reply. My G-sync has been working most of the time; I did some reading, and it is more than likely an issue with Nvidia's drivers and not DCS. I'm using Nvidia driver 353.06, which I found g-sync works 95% of the time. The newer drivers...good luck getting g-sync working. My performance with 1.5.3 is insanely smooth so far.

worked on all latest drivers last months, VSYNC is OFF tho usually

 

EDIT: I see you run Win7. With 10 Gsync is always on as soon as you log into GUI.

 

My monitor has an indicator LED that changes color to RED when in Gsync mode, since 10 its always red, desktop or game or youtube.

 

I have found that scrolling text is one of the bonuses of Gsync, it reads so much better when scrolling, even better than this Mac I am typing on.
