Yes, this is the behavior that I see. I will disable the unified slider for now and look forward to your changes. Hopefully, they can be applied in-place without having to revert to stock first.

Refresh rates above 99Hz don’t work at all on SDC. This also means that locking the framerate to anything between 50 FPS and 60 FPS doesn’t work, since the corresponding refresh rates are higher than 99Hz. HDR doesn’t seem to work at any unsupported refresh rate, even if it’s below 90Hz.

I personally don’t see myself using this mod any longer based on these observations.
