I have the same problem and would be interested in a solution or a hint how to further troubleshoot this.
Vorpx does not attach to the vanilla wow client (v1.12.1).
It works just fine for the retail and the wowclassic client but not for the vanilla client that is used for most private servers running the real vanilla wow.
Only the latest official build is supported (in DX11 mode), sorry.
Thanks for the quick reply! Would it be possible to also support the vanilla client in the future? Can I submit this as a feature request somewhere? :)
There is a quite active community of players e.g. on everlook.org which has 5-10k active players currently and I have seen some other people on this board here that tried to play vanilla too.
I’d like to second the request to enable dx9 support for WoW. I found what seems like the exact WoW experience I’ve been looking for and I was really sad to find out I couldn’t hook the game because it uses the older client with dx9. I was under the impression that most dx9 games worked with Vorpx. Is there any reason it won’t work for older versions of WoW? I’m thinking of trying out tridef just to see if I can get a similar stereo 3D effect but I’ve heard it’s not near as polished/good as vorpx.
