550.40.81: DLSS is not accessible in Proton games

Graphics / Linux Linux
1

With the 550.40.81 driver, DLSS options are not accessible in games running under Proton-GE 9-20. For example, the issue reproduces in Horizon Forbidden West and Dragon Age The Veilguard. The _nvngx.dll and nvngx.dll libraries are symlinked into the wine prefix from their locations in the system and the symlinks are valid.

This issue is not present with the previous 550.40.80 driver on the same system, the same games, Proton-GE version and the same wine prefix. DLSS is present and selectable in game options.

I can add that DLSS is available in game settings with the 565.77 driver. This does look like a regression in 550.40.81.
