So i have a 27in Acer 1440p g-sync display can't care less about the model no. I think it's xb271 something. My point is that after the Creators update I started seeing some tearing and to be honest I don't think my g sync is working after the update.I first experienced this in Fifa 17. I see high frame rates but there's some weird lag and tearing. For now, i just put on V-sync. Which was working just fine before the update. The settings are exactly the same as before.
g-sync is enabled for full screen and windowed in the Nvidia Control Panel (will refer to this as NCP form here on). The 3d settings for the game has g-sync on too and the in game settings are no limit fps, these setting used to work before.
Now the thing is I could just roll back the update but I'll probably have to eventually since Microsoft is so pushy with the updates and due to the fact that I'm going to be upgrading to a Ryzen 1700X from my current 2700k (OC 4.7GHz, Not sure that matters but just in case it does, leaving it out there) in the next week or so, just waiting on the mobo and ram to ship. And I've read int he forums that this update is required for Ryzen to run well / stable.
I'm currently using a gtx 970 strix. My 1080ti should be delivered today so I'll switch out the card and see if the problem persists. I am running the latest WHQL drivers.
hope someone can clear the confusion on this situation.
