ImmediatelyFast

• Fixed item lighting issue when using macOS

• Added support for Minecraft 1.21.6

• Fixed crash when Hey Wiki mod is installed

• Fixed font atlas resizing state inconsistency (Fixes rare JVM crash when using certain resource packs)
• Improved compatibility with mods which don't render into the batching buffer while batching
• Speed up buffer upload on Apple GPUs
  • This "reverts" an internal 1.21.5 change which caused a performance regression on Apple GPUs

v1.9.3

• Fixed linux AMD GPU flashing window issue caused by the framebuffer optimization
• Fixed Intel GPU graphical issue caused by the framebuffer optimization

v1.9.2

• Added new optimization: Avoid redundant framebuffer switching
  • This optimization reduces the number of framebuffer switches when rendering many different things in the world (entities, particles, block entities, ...) or the HUD to increase FPS.
• Fixed force draw handling (Fixes compatibility with Tweakermore and MiniHUD)
• Removed experimental universal HUD batching optimization
  • This optimization was disabled by default, but caused too many graphical issues when enabled, which are difficult to fix for a relatively small performance increase

v1.6.4

• Don't force draw the batch if the shader color changes, because that's already accounted for when collecting the data

v1.6.3

• Force draw batch if the scissor box or shader color changes (Fixes issue with Figura player list rendering)
• Clamp out of bounds shader color (Fixes issue with Dragon Survival "Magic Cast Meter")
• Disable experimental sign buffering if Effective is installed (Effective uses non-standard rendering which isn't compatible)

• Readded NeoForge support
• Added new experimental optimization: Avoid redundant framebuffer switching
  • It can be enabled in the config file (immediatelyfast.json) by enabling experimental_avoid_redundant_framebuffer_switching
  • This optimization shouldn't cause any issues and will be enabled by default in an upcoming release if no issues are reported
  • Any feedback regarding rendering issues or performance improvements is appreciated (You can find the discord link in the mod description)
