Installed and working on our server... works great, with no issues or problems (yet).
However, playing on a more populated server such as Bloodedge (he also installed ACE today), i have noticed severe lag when joining the server. After about 15-20 sec the lag is gone and it is pretty much playable. Occasionally bouts of lag throughout games though, that were never there before running UTDC.
Nothing outrageous but maybe getting fixed anywyas in v0.7... at least i can join and play now on Win7 x64!! Great work guys.
