ViewSonic XG270 - G-SYNC black screen issue [VRR Range Fix]

[Zealot]

Enabling Adaptive Sync on my XG270 sometimes causes my screen to turn black for a second when gaming.
This happened most often in Destiny 2 and Borderlands 3, I did not get a black screen while playing Overwatch.
I suspect this happens during <60fps frame drops since Overwatch never drops that low, whereas Bl3 is quite demanding and it happens often enough.
Google suggests to use CRU and turn VRR off at 40, however the XG270 already defaults to 48.
Others reported this to be a Nvidia Driver issue that was non existent pre Driver Version 399, but I do not want to roll back that far.
I have G-SYNC set to Full Screen and limited fps to 237 through control panel. Im running this monitor of a 1070.

This makes G-SYNC pretty much unusable currently, what can I do to fix this?

I think I may have found a solution; using CRU to set Vrate to 55 seems to have eliminated the black screen issue. So far ive played ~6hrs of Destiny2 and have not gotten a single black screen.

This actually worked for me and has stayed working for a good month now, thank you!

Just wanted to ask if this is still working for either of you. I might now have been doing it right the first time but I believe that the CRU fix didn't work for me.
