This may be known all ready but ill repost here just in case its not. I may have alluded to this in my other thread, but ive learned a bit more about it in the mean time. Gsync seems to randomly start being disabled entirely. I haven’t nailed down exactly the cause, but over time I seem to lose it entirely and the only thing that fixes it is to toggle adaptive sync on the monitor itself. It does seem to be related to low power state system boots (IE after sleeping). I have mine configured to sleep after 10 minutes of non use. Initially it was ok, and gsync worked fine, but over time (Not sure what i did) it seemed to just lose it entirely.
Just posting about this issue here in case it hasn’t been reported yet. Perhaps you’re aware of it and a firmware update will help fix it.
