I think that's mostly just NVIDIA RandR returning bogus refresh rates. At some point you could fix that by disabling the "DynamicTwinView" option, but it's been several years now since I last used the proprietary NVIDIA driver.
Running just 'xrandr' does correctly report 144Hz though, is there something else I should run to confirm that it's an Nvidia bug?
