Specs are: RTX 3070, Viewsonic XG2401, latest driver (551.86), latest Windows 11 build (23H2).
My driver settings are simple and as follows: "Enable for fullscreen mode"
Frame cap used in the video belongs to Special K, which I also used to monitor refresh rate of the screen (I don't know how it does it but it reflects the monitor OSD readout). I've tried a driver 1 year prior and I had a similar problem, so I wonder if it is a mix NVIDIA/Windows 11 issue.
I've tried disabling/enabling HAGS, MPOs, different combinations of both to no avail. I've also tried enabling driver vsync, no help.
With 30-146 range, game appears stutter free on the pysical screen. With 48-146 range, game constantly looks stuttery on the physical screen and quite horrible. Default range is 48-146 however and 30 FPS should just be able to sync to 60 hz without any problem. Increasing LFC range to something like 67-72 makes this problem even worse somehow (in that case, it shoots upwards of 93 hz constantly instead of syncing to 90 hz)

These are the default, non modified monitor settings as seen in CRU. When I tweak V rate to 30 or 36 from the 48, LFC starts working as it should at low framerates.
