Custom Resolution Utility (CRU)

[steve]

I have a FreeSync monitor with an advertised range of 48-144hz. The range limit meta-data in CRU confirms this is the case.

I am trying to use this monitor in g-sync compatible mode on an Nvidia RTX 2070. Overall it works okay, but I noticed some brightness flickering at the 60fps threshold. A little bit of troubleshooting with the OSD frame-rate display leads me to believe that the Nvidia driver is enabling LFC at 60hz/fps, and not at 48hz. This causes the monitor to oscillate between 60hz && 120hz, and presumably the panel brightness is quite a bit different between those frequencies.

I have tried both raising and lowering the min FreeSync value in CRU, but it has zero effect in my tests. This is a nuisance because a lot of games kind of assume 60fps is the sweet spot, so menus are capped right at the point that causes the most flickering.

Does anyone know if there is some trick to getting the driver to recognize the CRU FreeSync range? Alternatively feel free to just confirm that Nvidia ignores the stored range.
