Copy-pasting from the other thread, and I appreciate the response from SChin. Many devs do not take these issues seriously, and figure that because it's a small portion of their audience having the problem, it's not worth fixing. I hope that's not the case here.
Anyway, here's my post:
Having the same issues. I have G-Sync turned on and setup properly (as tested by Blur Busters -- in game V-Sync off, Nvidia control panel V-Sync on, G-Sync set for fullscreen only, etc.), I have the game running in exclusive fullscreen, I have the latest drivers, and I'm running an 8700K and 1080 Ti system with 16GB of RAM. Nothing is overheating, nothing is dangerously overclocked.
Some other details that may or may not help the devs:
The game is running on an SSD.
Even when the game is set to fullscreen, I'm still able to quite easily alt-tab out and perform other actions, with the game still running and displayed on my first monitor. This seems to be somewhat abnormal behavior for fullscreen games, at least in my experience. Typically, alt-tabbing is quite an ordeal, and can risk crashing a game (or at least causing some annoying screen flickers). Is the game truly running in exclusive fullscreen?
I have two monitors, both 144Hz, but only one (the one the game's running on) with G-Sync compatibility.
I'm playing through the Xbox Game Pass for PC.
I've completely uninstalled my drivers using Display Driver Uninstaller (performed properly -- I ran it in Safe Mode and as an Administrator), and then re-installed the latest ones.
I do not have GeForce Experience. The only overlay tool I have is Rivatuner Statistics Server, for capping the FPS at 141. I've tried without that software as well.
At 1080p with my current system, I see frequent FPS drops into the low 80s, and out in the wilds, it's usually well above 100. However, even at high framerates, the stuttering is constant. I'm not exaggerating. Every few seconds, stutter. Standing still but turning the camera, stutter.
And yes, I've tried with G-Sync off, too, as well as with normal in-game V-Sync on (that just made things worse).
I would be more than happy to record a clip of the stuttering in action, or provide any other details needed by the devs.
