  Thursday bug bash

  G'day Rat Racers!This new update fixes bugs, improves performance and adds some goodies that didn't initially make it into the last major update. This update also updates the Game Manual significantly to bring it up to date with the Anniversary update!Improvements:Improved GPU performance in cases where the GPU was pixel shader or texture fillrate bound.Increased the brightness of Beach's night time lighting.Improved responsiveness of the game's dynamic resolution scaling under high GPU load. This should resolve performance issues at high GPU load on some older PCs.Added an approximate latency measurement to the in-race HUD; this displays how delayed online race interactions may be, in ms, and is affected both by the system performance and the network latency of all players in the lobby. NOTE: This value may be different across systems in the same lobby; this is normal and is no cause for concern.Improved disconnection detection for players in lobbies with mixed Direct/relay network connections.Changes:CPU players now use random names instead of a CPU number & Rat fur colour.Bugfixes:Fixed a bug where the LOADING indicator could vanish too early on game boot while the game was still prewarming shaders.Fixed a bug where the game's in-race HUD would become stuck on in the background of the results scoreboard if a player changed their race POV to spectate another player after finishing their race.Fixed a bug where Shields would sometimes be instantly destroyed when used in replays made from online races.Fixed a bug where Missiles that would target a player behind another player in online mode and score a hit could visually appear to miss on the thrower's screen.Fixed a bug where it was possible for all players in an online lobby to get stuck in an infinite "Waiting for Players" loop if the lobby master's client disconnected before the race fully began.Fixed a bug where it was possible to accidentally load into a Quick Race while exiting an online race while playing Rat...

  Rattus Velocitas hotfix released.

  G'day again, Rat Racers! This small hotfix resolves an issue where CPU players would overzealously avoid obstacles that were well out of the way, making them comically easy to beat in cases where they should have been pressuring a well-performing player a lot more. In particular, Forest races should be completely fixed now!

Don't get caught snacking!Added a new Stage Hazard to Forest: Lightning Strikes. Only appearing during storms, these powerful bolts slow players on contact. Thruster Classes are now in the game.

  Rattus Velocitas hotfix released

  G'day Rat Racers,If you found Laps and Finishes sometimes not counting in online multiplayer, this hotfix resolves this issue. Changes:Fixed a bug where laps/finishes weren't counting when crossing the finish line if at least one player in the lobby had high latency. NOTE: This does introduce a slight delay sometimes when completing a lap or finishing a race. This is intentional.Improved the client-side prediction implementation.
