Star Trek Online continues to approach, the game's development team continues to make more last-minute polishes. As outlined in the most recent entry in the Path to F2P blog series, one improvement directly pertains to the game's graphics, putting in DirectX 11 support for players whose cards can support the display mode. While it won't offer a performance increase for every player, there are players who have reported big jumps in FPS with DirectX 11 on while testing on the Tribble server.
The other major improvement deployed to the test server is a change to the game's rank display. Previously, the game displayed levels by rank and grade -- a player would move from Commander 10 (level 29) to Captain 1 (level 30), which was evocative of the setting but a bit hard to process at a glance. So the display has been trimmed up and improved, with player level displaying as a rank followed by the level (the previous example would now display as Commander 29, then Captain 30). No actual levels have been lost -- it's just a change to ensure that new players have an easier time understanding the level differences.
