Okay another update.
I've tried to compile for DirectX9 and ran into some unexpected problems which require me to install additional developer software and libraries, blabla, ipso facto, we won't be able to release the Directx9 client right away unless we are willing to delay the release of open beta for another few hours, which we are not going to do.
So, right now, I will upload the 1.19 patch (OpenGL only), and when the download is ready, the beta will open. Bear in mind my connection is <sarcasm> great </sarcasm>, so yeah, as soon as that uploads in 15-30(?) minutes, we're good to go.
The DirectX9 version should come a bit later, probably tomorrow or so. It was not in our intent to release Dx9 client at all (so early), but I'm gonna do this for the sake of all those unable to run OpenGL, so please don't complain, it's the best we can offer you right now in this testing stage. Thank you all and see you very soon, I'll keep updating this thread on the go!
