Does anyone else's copy of GTA V only offer 0.834x and not 0.883x scaling?

Hello! I hope it's okay to ask this here.
My copy of GTA V only gives me the option for 0.834x scaling, and not the 0.883x scaling that the documentation and .ini talk about (to get Ultra FSR). I am concerned that this might cause it to not work correctly. I checked the Debug output, and I can see that it is engaged, but it gets engaged at launch whether scaling is enabled in the game options or not. I'm otherwise running fullscreen, 60hz, 3840x2160 (4k).
Thank you!!!

Oh geez, I'm so sorry, once I actually got in-game, I could see the debug tool updating like crazy. I could also see that FSR was being toggled off when I hit F3...
