I have no problems with the D3D7 client, but as far as I know D3D9 and D3D11 won't work with 2010-P1.
If I am violating anything, please tell me, so I remove it ASAP....Thanks to Ripley, it is currently available here...
I know this thread is very old. But I got a question about the latest orbiter beta version. What is the latest orbiter beta version? I only saw the latest orbiter beta version is 121103. Thanks!
The difference with these beta packages is that they require an svn client to install.
They don't require it anymore, see here: http://www.orbiter-forum.com/showthread.php?p=500936&postcount=572
However, using the version control client is the preferred way of distribution, because it will only need to download deltas, not full versions as with the ZIP archives mentioned above.
