Improved game stability and "newly implemented full support" for anti-aliasing are among the major tweaks developer Bohemia has brought to the PC military simulator. The patch can only be installed over version 1.00 or 1.01 of the recently released game, but retains multiplayer compatibility with all past versions (1.00, 1.01 and 1.02). nope
"We believe [anti-aliasing] increases visual quality significantly without any major performance impact," said Bohemia.
The studio added that "it is not recommended to use any savegames created in versions 1.00 or 1.01," though saves created under the previous 1.02 patch should work just fine.
