I think in theory it’s less effort for them because they only need to build the server side engine that the client connects to, instead of also building a local version.
They actually already implemented Vulcan. Though in true CIG fashion it’s pretty unstable compared to DX11. Also those free fly events are ironically a terrible time to play the game because the fragile ass servers get super bogged down. Outside of those events it’s usually decently stable.
