Distant Horizons

Highlights:

• Dedicated/LAN Server support

• Changed the DH logo
• Removed Multiverse Similarity percent
• Fixed vertical fog
• Up API version 3.0.1 -> 4.0.0
• Massively reduced memory requirements and GC stuttering
  • DH can now run with as little as 2-4 GB of memory (depending on CPU settings)

Full Changelog

Additions:

• Server support - pshsh
  • Server LOD generation
  • Server Multiverse handling
  • dedicated servers
  • LAN servers
• Add DH/Vanilla fading
• Add support for N-sized world generation
• Add recalculate heightmap config
  • for use with world painter worlds or whenever the heightmap is incorrect
• Add Oculus 1.7 to the list of incompatible mods
  • Oculus needs to update to use the new DH API
• Add pshsh to the author list
• Add partial mod incompatibily chat warnings
  • Chunky, WWOO, and Alex's Caves
• Re-added INTERNAL_SERVER distant generator model
  • This mode will ask MC's server to generate the chunks.
  • This mode allows for more accurate generation at the cost of world size and server thread lag
• Add config assumePreExistingChunksAreFinished
  • This may help with situations where pre-existing chunks were created by third-party program and are incorrectly running world gen.
• Dyanimc Thread allocation - Pshsh and James
  • DH now has a single thread count config
  • This should reduce the chance of DH using 100% CPU with lower CPU presets
  • The CPU preset has also been increased from LOW -> BALANCED
• Add options to show/hide some DH F3 screen info
  • memory pools are hidden by default since they aren't needed unless debugging said pools is needed
• Add logs for when a repo has finished closing
  • If Sqlite is taking a long time flushing the WAL file, this should help show that
• Add validateBufferIdsBeforeRendering Config
  • Enabling this drastically reduces FPS but can be helpful for troubleshooting
• Add a chat warning if the vanilla render distance is higher than recommeneded
  • DH can be more easily overwhelmed if the vanilla render distance is too high
  • And vanilla CPU use is much higher
• Add world gen/import progress overlay
• Add automatic overdraw config
  • when overdraw is set to "0.0" DH will determine the best overdraw based on the vanilla render distance
  • this also affects vanilla fading and will make the vanilla render distance appear a bit further when fading is enabled
• Add the ability to change beacon beam heights - zJannyAT

Improvements:

• Optimize ChunkWrapper getBlockState - Builderb0y
• Optimize sky light for LODs - Builderb0y
• Improve adjacent chunk lighting logic - CreepermeYT
• Reduce file handler task count when updating QuadTree nodes
• LOD updates will happen around the player instead of FIFO
• Optimize DH cloud rendering
  • Cull behind the camera
  • Change cloud model to smooth transition
  • Slightly increase cloud speed
• Improve generic object render profiling
• Cache arrays used during Generic Object Rendering
• Move some LOD Building logic off of the render thread
• Improve Buffer upload speed and remove buffer upload threadpool
  • Buffer uploading is now handled on the Lod Builder threadpool
• Rewrote object pooling to massively reduce memory use and generated garbage
  • DH can now run with as little as 2 GB of ram (depending on CPU load) and in MC 1.21.4 memory per second with world gen was between 500 MB and 1 GB per second, in comparison to 6 GB/s previously
• Reduce garbage generated when interacting with Sqlite
• Added number formatting to migration progress logs
• Reduce duplicate warnings when loading old worlds

Changes:

• Changed the Logos
  • new logos created by Pankakes
• Hide "Distant Horizons Overloaded" chat message
  • message can be enabled via config for testing
• Vertical quality dropoff is slower
• Split the config into: Client, Common, Server
• Increase far clip plane distance slightly
• Increase default render distance 128 -> 256
• Added brown mushrooms to the list of ignored blocks
  • fixes some swamp rendering issues
• Removed world gen timeout
  • It was originally added to prevent locking up world gen threads that got stuck in an infinite loop, however it never solved that problem so it was just an annoyance.
• Rename world gen thread pool in F3 screen "World Gen" -> "World Gen/Pull Chunk"
  • This thread pool has always handled both pulling pre-existing chunks and generating missing chunks, however there was some confusion where some people thought it only generated chunks
• Increase Default thread preset LOW -> BALANCED
  • due to the addition of dynamic thread allocation the number used for each prest was changed slightly
• Change CPU Preset config default values

Bug Fixes:

• Hide closed database warnings
• Fix some instances of extremely high file handler job counts
• Fix config file handler corruption due to concurrent reading/writing
• Fix F3 menu showing the same level multiple times
• Fix the near clip plane appearing when zooming
• Fix JOptionPane causing Mac's with other mods freezing during load
• Fix generic renderer not using material type for shader use
• Fix a few logs not showing positions correctly
• Fix unnecessary JarUtil error logging
• Fix GLProxy skipping some render thread tasks
  • This may solve some memory leaks or rendering holes
• Fix height fog
• Fix crashing when other mods null the MVM or Projection matricies
• Fix crashing when setting some config values to 0
• Fix pack.mcmeta warnings
• Fix DH preventing server shutdown in some cases
• Fix an EXCEPTION_ACCESS_VIOLATION rendering crash
• Fix Sqlite memory leaks
• Fix infinitely growing memory when changing dimensions
• Fix auto updater failing in some cases and improve logging
• Fix rare concurrent modification when changing generic rendering cubes
• Fix beacons disappearing in some situations
• Fix stairs, slabs, and glass sometimes not appearing in LODs
• Relocate Sqlite under a DH namespace to prevent interference with other mods shading or adding SQLite - pshsh
• Fix rare concurrency error on world gen shutdown

Removals:

• Multiverse similarity percent
  • Levels will now use the hashed seed in their folder name instead
  • This is a significantly more relyable method for differentiating levels.
