Unable to select upscaling, it is grayed out. If I try to do it from settings in the main page, it has an information saying it can only be enabled in a RTX world. If I start a RTX world (official NVIDIA ones), it is still grayed out, but no information why it is grayed out.
Tested in both 1080p and 2k resolution, full screen and windowed mode.
Windows 10
RTX 2080 TI
Intel Core i9
64GB RAM
