Distant Horizons

MC 1.21 support

API version increased 2.0.0 -> 2.1.0

Added "Auto" update branch that sticks to stable or nightly builds respectively.

Increased LOD generation speed for pre-generated worlds.

Reduced CPU usage when traveling over unchanged LODs.

Fixed some mystery OpenGL related crashes.

Reduced compression slightly to improve speed.

• If the jar is a nightly (unstable) build it will only update to nightly builds and if stable it will only update to stable builds
• This should fix issues with people accidentally updating to the nightly/stable build

• This should increase LOD generation speed significantly

• Should help some people diagnose why they're game is stuttering so bad
• This warning can be disabled via the DH config

• DH should crash if the database is determined to be locked

• This should fix a lot of random crashing issues and with Sodium/Steamdeck

• This should reduce CPU use when flying over already generated chunks/LOD

• Improved visuals

• This specifically references mods like chunky causing holes due to generating faster than DH can keep up

• Faster compression at a slight file size increase
• The speed difference between 3 and 4 is pretty big with only a very minor file size change.

• "I Paid For The Whole CPU" should no longer totally overload the CPU

• This is because Blendium is no longer supported

• No forge support for 1.20.6 due to Forge compiler issues
• Added NeoForge support for 1.20.6

• 1024 at medium can be loaded with 4 GB of memory

• Note: This will only affect new worlds, old databases will be migrated to the new format, but have to be manually vacuumed to shrink their file size.

• This means there were some breaking API changes

• World gen also starts faster after loading into the world.

• IE hollow structures will no longer render incorrectly at lower detail levels

• Added LZMA as the new default compression option
  • LZMA provides roughly 3x the compression vs the previous compressor
• Add lossy world compression, defaults to "visually equal"

• Fixes holes with world gen - James
• Overhaul the database format - James
• Add automatic DB migration - James
  • Migration progress can be seen in the log and f3 menu
• Removed DhRenderData - James

• Iris already hid DH rendering anyway, so this just makes it clearer

Fix holes in the world when using world gen - James

Fix world gen re-generating the same terrain - James

Fix world gen for extreme render distances - James

Fix ocean lighting grid issue - James

Fix C2ME support - James

• Changing C2ME's config should no longer be necessary to run it with DH.

Fix SSAO and Fog not applying when Optifine shaders are enabled - James

Fix BiomeWrapper warning about null level on startup - James

Fix missing indium crashing with a messy error when java.awt is headless - James

• The error message will now be much clearer and in most cases, should have a pop-up dialog explaining the problem.

Fix Z-fighting at very high heights - James

Fix red LODs rendering in random places

• IE Added a config which is disabled by default to render overlapping quad errors - James

Fix rendering holes (most of the time) - James

Fix F3 menu not removing levels after leaving when multiverse support is active - James

Fix LodRenderSections not stopping load futures when closed - James

Fix a rare concurrent lighting engine issue with ChunkWrapper.getBlockLightPosList() - James

Fix purple Chisels & Bits block rendering - Pierre Remacle

• IE make Chisels & Bits blocks transparent

Fix ThreadPool null pointer before world startup - James

Fix world gen lockup if the file system fails - James

Fix chunk break/place events not triggering fabric updates post MC 1.17 - James

Fix Optifine not running in the dev environment - James

Fix light engine out of bounds for MC 1.16 and 1.17 - James

Fix File handler repos not closing - James

Fix transparent ocean floors at low detail levels - James

Fix warning about BiomeWrapper null level on startup - James

Fix white grass/water if the biome is null - James

Fix optifine 1.16 support - James

Fixed mod auto-updating on quilt - coolGi

Fix thread pool error logging after shutdown - James

Fix corrupt data or moving data between MC versions causing monoliths - James

Fix #49 shaders render incorrectly - IMS

• This is specifically fixed for Iris 1.7.0+

Fix #94 Rendering issues with Immersive Portals

Fix #414 Added (nearly) unlimited vertical quality graphics option

Fix #449 LodNodeBufferBuilder crash due to index out of bounds

Fix #595 crash on save and exit - James

Fix #597 Show Create logo in DH's update menu

Fix #613 multiplayer failing due to folder not existing - James

Fix #615 lag when rapidly breaking/placing blocks - James

Fix #638 optifine not rendering on 1.16 + 1.17

Fix #640 world gen holes not filling in

Fix #641 seamless overdraw issues

Fix #650 Fix Indium missing messages not displaying correctly in some cases - James

Fix #663 Fix world gen holes - James

Fix #670 Remove outdated world gen options from tooltip - James

Fix #673 Chunks without a position are ignored - James

Fix #680 Massive Memory Usage by ColumnRenderSource#renderDataContainer - James

• The experiment was interesting, but ultimately failed. There were a number of issues rendering entities and it only ever worked on Fabric.

• Near fog was originally added back in DH 1.0 in case we couldn't remove vanilla fog, which has since proven to not be an issue.

• Unlimited quality is unnecessary and due to how the renderer is currently set up, unable to be run on any machine at higher render distances.

• Cave culling is currently bugged and to prevent holes in the ocean that show the void this is the temporary solution.
