I play on a 144Hz freesync display and haven't noticed anything like that and have about 10 hours logged in SP & MP. I have a vega 56. Been a few days since I played though so maybe a recent patch screwed things up?
No, the so-called 60Hz+ bug people are talking about and claim happens to everyone has not at all been technically verified.
People perpetuating this myth, including the article here, are just parroting a single reddit post where an alleged dev was careless enough to say that 'they might have seen something similar once on a machine where hdr was active without an hdr monitor'.
Now this pops up again and again as 'admitted by the devs', despite any proof or serious investigation from reputable sites. Digital Foundry, famed for graphic engine analysis, just covered this game without mentioning any of this.
It's just that some players claim to 'feel' it's less fluid than when locked at 60Hz, despite nominal fps and frametimes at 144Hz that correlate normally. They even attack or try to belittle people who state they have no problems of that nature.
I run a gtx970,1080p,144hz Gsync @120fps, and there are no problems seen or measured at my machine, and I can easily spot the difference between 120hz and 144hz. For me this game is just as fluid as for instance Everspace @ 120fps. Decreasing the game to 60Hz does not make it more fluid either, which is logical if you had no problems to begin with.
Now that's not saying there are no problems for others, but bold claims that all 60hz+ players are suffering from the same bug are just lies.
This seems exactly like the Poscap scandal a few weeks ago, where Reddit & Youtube 'investigators' cried hardware defect, parroted all the way to news sites posing it as truth, but which was fixed with a driver update a week later.
