Thanks for the welcome.
GeForce GTX 1080 Ti
Yes, and yes.
Very close to the latest. I think there's some brand new drivers recently that I haven't updated, but pretty recent.
I actually did some testing myself based on your questions.
After changing my refresh rate on my monitor down to 60Hz from 165Hz, the problem persisted. However, after disabling G-Sync, all of my problems seemed to vanish. Even when I set my monitor back to 165Hz, the problems did not exist. So, the issue seems to lie with G-Sync on the monitor causing the problem for some reason. Any idea why this might be the case?
