After getting past #2698 (by upgrading Mesa it seems), I am now observing that games with DLSS-FG support are unable to detect the feature as being available. When the AMD GPU is hidden, the games detect FG just fine.

This is the first 2MB of the log - the full log is 160MB and doesn't look useful. Within the first 10K lines there's a lot of nvapi and other nvidia related log lines, and I assume those are the interesting ones, but let me know and I will upload more log content if required.

In retrospect, this should have been filed under dxvk-nvapi, so I've done that.
