I've had zero issues so far and the game runs stable and buttery smooth. I'm getting ~70FPS on average at 1440p, with occasional drops down to the mid 60's, but never below 60.
I'm using a mixture of Ultra and High settings (everything Ultra, except shadows, clouds, and reflections at high), with motion blur turned off. FOV is set to 90, frame rate set to unlimited, fullscreen mode, and V-Sync off within the application (I've got G-Sync and V-Sync enabled in NVIDIA control panel [yes, both are enabled, as is suggested by NVIDIA, which works flawlessly for me in all games], along with a frame limit of 141 for my 144Hz monitor).
I haven't experienced any artifacting, crashing, stuttering, or excessive frame skipping during gameplay. My system is an R5 3600 paired with a 2070 Super, 16GB RAM at 3600 MHz, and the game is installed on an NVMe SSD.
Edit: Also, dynamic resolution is disabled, 16X AF is enabled through NVIDIA control panel, and anti aliasing is set to TAA; I forgot to mention that
