-# TODO does this need updated for when a game has multiple APIs? See #580
+## Get rendering API from PCGamingWiki compatibility list
+## This is missing some supported games (such as NieR:Replicant and Monster Hunter World) but is generally a good reference point

+## For compatibility reasons we use d3d11.dll as the SpecialK DLL name for Direct3D 11 games, as this seems to be more compatible than dxgi.dll on Linux -- Mainly when it comes to using ReShade and SpecialK
+## ReShade and SpecialK work better together for Direct3D 11 games if we use d3d11.dll as the name
+##
+## Behaviour is this:
+## - If we find Direct3D 11 as the rendering API for our game, use d3d11.dll as the SpecialK DLL name
+## - If we find an unknown rendering API for our game, use dxgi.dll as a fallback
+## - If we cannot find our game in the list, assume D3D11 and fall back to d3d11.dll
