Changelog

• Performance optimizations:
  • SSE2 is now enabled throughout the engine. This enables optimizations throughout the engine, but requires a CPU from at least 2003!
  • Character and object animation has been greatly optimized, increasing FPS during large team fights
  • Improved the performance of particle sprite rendering
  • Fixed an issue that caused some particles to do more collision calculations than required
  • Fixed an issue with some particle effects and other attachments causing extra animation updates on characters
  • Fixed unnecessary animation work being done on local game sessions
  • Reduced the performance impact of querying item data during gameplay, particularly for viewmodels and the HUD player model
  • fps_max now efficiently and accurately limits the FPS on all systems
  • Reduced GPU latency using DXD9Ex
  • Reduced the possibility of stutters when encountering new models during gameplay
  • Optimized various aspects of player and weapon rendering
  • Fixed an issue where collision was queried inefficiently during local player movement
• Load time optimizations:
  • Game startup has been improved by about 2x
  • Map load time has been improved significantly
• Sound improvements:
  • Increased the number of sounds that can play at once from 128 to 256 unique sounds
  • Added fully threaded sound: removes sound stutters, improves performance, greatly reduces latency and increases sound quality due to improved sampling
• HUD fixes:
  • Fixed the loading screen tip suddenly changing during map loads
  • Fixed various HUD exploits related to showing/hiding elements (should also improve performance)
  • Optimized how the HUD handles data updates
  • Optimized the rendering of text and fonts
  • Optimized the rendering of HUD elements in general and their animations
• Gameplay fixes:
  • Deploy time bonuses are now considered when applying the switch from bonus, commonly encountered with the Degreaser
  • Fixed the MvM bomb carrier announcer voice line playing when compression blasting a TFBot with the intel off of its path
  • Fixed class limits not being enforced during a respawn wave
  • Slows now apply consistently in all movement directions
  • Fixed the Baby Face's Blaster speed boost being removed while affected by a slow
  • Fixed the pre-round freeze not being applied properly on the first round of a matchmaking game
  • Fixed FPS over 1000 causing simulation issues in a local server
• Networking fixes:
  • Increased the default rate from 80000 to 131072
  • Set the default update rate and usercmd rate to be equal and aligned to the game tick
  • Reduced maximum lag compensation from 1 second to 0.5 seconds
  • Reduced maximum cl_interp value from 0.5 seconds to 0.2 seconds
