It is important to note that your servers or the servers you love to play on will not magicly be able to support over 32 players. As in the first post in this thread, you will need a beast of a processor that can chug through single threaded code to even think about going above 32, and even then not all maps will perform the same above that limit.
Like before tank maps will eat up more CPU cycles, so if you like to run tank maps, your limit will have to be lower. Infantry maps, especially smaller ones with lots of twists and turns that keep alot from being rendered all at once (Danzig), will perform the best with higher player counts. But then again aslo keep in mind the maps out there were not designed for 32+ players.
But we'll have more info on this closer to the patch release along with some guidelines for server admins.
