v0.11.12
What a Vulkan game is told is now correct. The refusal added in 0.11.8 pointed at "DLSS5-Feeder's Vulkan layer (layer-x64 in its zip)" — a path that does not exist, and it read as though Vulkan were a dead end. It is not: DLSS5-Feeder covers Vulkan. The part this tool cannot do is ReShade's side, because it installs ReShade as a dxgi.dll beside the exe and a Vulkan game never loads that file.
The message now says so, and gives the route: run ReShade's own setup, choose Vulkan, set AddonPath under [ADDON] in ReShade.ini, then install the Feeder files as for any 64-bit game, with run-with-feed-layer.bat as the fallback if the log reports missing interop entry points.
